San Francisco
–
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

Bus
–
A bus is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers, many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare, in many jurisdictions, bus drivers require a special licence above and beyond a regular drivers licence. Horse-drawn buses were used from the 1820s, followed by steam buses in the 1830s, the first internal combustion engine buses, or motor buses, were used in 1895. Recently, interest has been growing in hybrid electric buses, fuel cell buses, as of the 2010s, bus manufacturing is increasingly globalised, with the same designs appearing around the world. Bus is a form of the Latin word omnibus. The first horse-drawn omnibus service was started by a businessman named Stanislas Baudry in the French city of Nantes in 1823, Nantes citizens soon gave the nickname omnibus to the vehicle. The omnibus in Nantes was a success and Baudry moved to Paris, a similar service was introduced in London in 1829. The first mechanically propelled omnibus appeared on the streets of London on 22 April 1833, in parallel to the development of the bus was the invention of the electric trolleybus, typically fed through trolley poles by overhead wires. The Siemens brothers, William in England and Ernst Werner in Germany, sir William first proposed the idea in an article to the Journal of the Society of Arts in 1881 as an. arrangement by which an ordinary omnibus. The first such vehicle, the Electromote, was made by his brother Dr. Ernst Werner von Siemens and presented to the public in 1882 in Halensee, Germany. Although this experimental vehicle fulfilled all the criteria of a typical trolleybus. Max Schiemann opened a trolleybus in 1901 near Dresden, in Germany. Although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system, in the early days, a few other methods of current collection were used. Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911, in Siegerland, Germany, two passenger bus lines ran briefly, but unprofitably, in 1895 using a six-passenger motor carriage developed from the 1893 Benz Viktoria. Another commercial bus line using the same model Benz omnibuses ran for a time in 1898 in the rural area around Llandudno. Daimler also produced one of the earliest motor-bus models in 1898, the vehicle had a maximum speed of 18 kph and accommodated up to 20 passengers, in an enclosed area below and on an open-air platform above. With the success and popularity of bus, Daimler expanded production, selling more buses to companies in London and, in 1899, to Stockholm

Trolleybus
–
A trolleybus is an electric bus that draws power from overhead wires using spring-loaded trolley poles. Two wires and poles are required to complete the electrical circuit and this differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there have been, currently, around 300 trolleybus systems are in operation, in cities and towns in 43 countries. Altogether, more than 800 trolleybus systems have existed, but not more than about 400 concurrently, the trolleybus dates back to 29 April 1882, when Dr. Ernst Werner Siemens demonstrated his Elektromote in a Berlin suburb. This experiment continued until 13 June 1882, after there were few developments in Europe. In 1899, another vehicle which could run either on or off rails was demonstrated in Berlin, routes followed in Eberswalde and Fontainebleau. Max Schiemann on 10 July 1901 opened the worlds fourth passenger-carrying trolleybus system, although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system. In the early days there were a few methods of current collection. The Cédès-Stoll system was operated near Dresden between 1902 and 1904, and in Vienna, the Lloyd-Köhler or Bremen system was tried out in Bremen, and the Cantono Frigerio system was demonstrated near Milan. Throughout the period, trackless freight systems and electric canal boats were also built, Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911. Apparently, though it was opened on 20 June, the public was not admitted to the Bradford route until the 24th, Bradford was also the last to operate trolleybuses in the UK, the system closing on 26 March 1972. The last rear-entrance trolleybus in Britain was also in Bradford and is now owned by the Bradford Trolleybus Association, birmingham was the first to replace a tram route with trolleybuses, while Wolverhampton, under the direction of Charles Owen Silvers, became world-famous for its trolleybus designs. There were 50 trolleybus systems in the UK, Londons being the largest, by the time trolleybuses arrived in Britain in 1911, the Schiemann system was well established and was the most common, although the Cédès-Stoll system was tried in West Ham and in Keighley. Smaller trackless trolley systems were built in the US early as well, the trackless trolley was often seen as an interim step, leading to streetcars. Buses and trolleybuses in particular were seen as entry systems that could later be upgraded to rail as appropriate, some trolleybus lines in the United States came into existence when a trolley or tram route did not have sufficient ridership to warrant track maintenance or reconstruction. In a similar manner, a proposed tram scheme in Leeds, worldwide, around 300 cities or metropolitan areas are served by trolleybuses today. See also Trolleybus usage by country, for example, new systems opened in Lecce, Italy, in 2012 and in Malatya, Turkey, in 2015

Light rail
–
Light rail, light rail transit or fast tram is urban public transport using rolling stock similar to a tramway, but operating at a higher capacity, and often on an exclusive right-of-way. A few light rail networks tend to have closer to rapid transit or even commuter rail. Other light rail networks are tram-like in nature and partially operate on streets, Light rail systems are found throughout the world, on all inhabited continents. They have been popular in recent years due to their lower capital costs. The term light rail was coined in 1972 by the U. S, Urban Mass Transportation Administration to describe new streetcar transformations that were taking place in Europe and the United States. In Germany the term Stadtbahn was used to describe the concept, and many in UMTA wanted to adopt the direct translation, however, UMTA finally adopted the term light rail instead. Light in this context is used in the sense of intended for light loads and fast movement, the infrastructure investment is also usually lighter than would be found for a heavy rail system. The Transportation Research Board defined light rail in 1977 as a mode of urban transportation utilizing predominantly reserved, electrically propelled rail vehicles operate singly or in trains. LRT provides a range of passenger capabilities and performance characteristics at moderate costs. Light rail is a generic international English phrase for these types of rail systems, the use of the generic term light rail avoids some serious incompatibilities between British and American English. The word trolley is used as a synonym for streetcar in the United States. A further difference arose because, while Britain abandoned all of its trams except Blackpool after World War II, when these cities upgraded to new technology, they called it light rail to differentiate it from their existing streetcars since some continued to operate both the old and new systems. Conventional rail technologies including high-speed, freight, commuter/regional, and metro/subway/elevated urban transit systems are considered heavy rail, people movers and personal rapid transit are even lighter, at least in terms of capacity. Monorail is a technology that has been more successful in specialized services than in a commuter transit role. Due to varying definitions, it is hard to distinguish between what is called light rail, and other forms of urban and commuter rail, a system described as light rail in one city may be considered to be a streetcar or tram system in another. Conversely, some lines that are called light rail are in very similar to rapid transit, in recent years. Some light rail systems, such as Sprinter, bear little similarity to urban rail, in the United States, light rail has become a catch-all term to describe a wide variety of passenger rail systems. There is a significant difference in cost between these different classes of light rail transit, tram-like systems are often less expensive than metro-like systems by a factor of two or more

Streetcar
–
A tram is a rail vehicle which runs on tracks along public urban streets, and also sometimes on a segregated right of way. The lines or networks operated by tramcars are called tramways, Tramways powered by electricity, the most common type historically, were once called electric street railways. However, trams were used in urban areas before the universal adoption of electrification. Tram lines may run between cities and/or towns, and/or partially grade-separated even in the cities. Very occasionally, trams also carry freight, Tram vehicles are usually lighter and shorter than conventional trains and rapid transit trains, but the size of trams is rapidly increasing. Some trams may also run on railway tracks, a tramway may be upgraded to a light rail or a rapid transit line. For all these reasons, the differences between the modes of rail transportation are often indistinct. In the United States, the tram has sometimes been used for rubber-tired trackless trains. Today, most trams use electrical power, usually fed by a pantograph, in some cases by a sliding shoe on a third rail. If necessary, they may have dual power systems — electricity in city streets, trams are now included in the wider term light rail, which also includes segregated systems. The English terms tram and tramway are derived from the Scots word tram, referring respectively to a type of truck used in coal mines and the tracks on which they ran. The word tram probably derived from Middle Flemish trame, a Romanesque word meaning the beam or shaft of a barrow or sledge, the identical word la trame with the meaning crossbeam is also used in the French language. The word Tram-car is attested from 1873, although the terms tram and tramway have been adopted by many languages, they are not used universally in English, North Americans prefer streetcar, trolley, or trolleycar. The term streetcar is first recorded in 1840, and originally referred to horsecars, when electrification came, Americans began to speak of trolleycars or later, trolleys. The troller design frequently fell off the wires, and was replaced by other more reliable devices. The terms trolley pole and trolley wheel both derive from the troller, Modern trams often have an overhead pantograph mechanical linkage to connect to power, abandoning the trolley pole altogether. Conventional diesel tourist buses decorated to look like streetcars are sometimes called trolleys in the US, the term may also apply to an aerial ropeway, e. g. the Roosevelt Island Tramway. Over time, the trolley has fallen into informal use

Cable car (railway)
–
A cable car is a type of cable transportation used for mass transit where rail cars are hauled by a continuously moving cable running at a constant speed. Individual cars stop and start by releasing and gripping this cable as required, the first cable-operated railway, employing a moving rope that could be picked up or released by a grip on the cars was the Fawdon railway in 1826, a Colliery railway line. The London and Blackwall Railway, which opened for passengers in east London, England, the rope available at the time proved too susceptible to wear and the system was abandoned in favour of steam locomotives after eight years. In America, the first cable car installation in operation probably was the West Side and Yonkers Patent Railway in New York City, the cable technology used in this elevated railway involved collar-equipped cables and claw-equipped cars, and proved cumbersome. The line was closed and rebuilt, and reopened with steam locomotives, beauregard demonstrated a cable car at New Orleans and was issued U. S. Other cable cars to use grips were those of the Clay Street Hill Railroad, the building of this line was promoted by Andrew Smith Hallidie with design work by William Eppelsheimer, and it was first tested in 1873. The success of these grips ensured that this became the model for other cable car transit systems. In 1881 the Dunedin cable tramway system opened in Dunedin, New Zealand, both of these innovations were generally adopted by other cities, including San Francisco. In Australia the Melbourne cable tramway system operated from 1885 to 1940 and it was one of the most extensive in the world with 1200 trams and trailers operating over 15 routes with 103 km of track. Sydney also had a few cable tram routes, Cable cars rapidly spread to other cities, although the major attraction for most was the ability to displace horsecar systems rather than the ability to climb hills. Thus, for a period, economics worked in favour of cable cars even in relatively flat cities, for example, the Chicago City Railway, also designed by Eppelsheimer, opened in Chicago in 1882 and went on to become the largest and most profitable cable car system. As with many cities, the problem in flat Chicago was not one of grades and this caused a different approach to the combination of grip car and trailer. After 1896 the system was changed to one on which a car was added to each train to maneuver at the terminals, while en route. On 25 September 1883 a test of a cable car system was held by Liverpool United Tramways and Omnibus Company in Kirkdale and this would have been the first cable car system in Europe, but the company decided against implementing it. Instead the distinction went to the 1884 route from Archway to Highgate, north London, the installation was not reliable and was replaced by electric traction in 1909. Other cable car systems were implemented in Europe, though, among which was the Glasgow District Subway, the first underground cable car system, in 1896. For a while hybrid cable/electric systems operated, for example in Chicago where electric cars had to be pulled by grip cars through the loop area, due to the lack of trolley wires there. In the last decades of the 20th century cable traction in general has seen a revival as automatic people movers, used in resort areas, airports, huge hospital centers

San Francisco Municipal Transportation Agency
–
The San Francisco Municipal Transportation Agency is an agency created by consolidation of the San Francisco Municipal Railway, the Department of Parking and Traffic, and the Taxicab Commission. SFMTA was established by the passage of Proposition E in November 1999, the measure, promoted by the transit riders group Rescue Muni, among others, established service standards for the agency and made a number of changes to the laws governing it. Prior to the passage of Proposition E, the Muni was governed by the Public Transportation Commission, both bodies were dissolved upon the full implementation of Proposition E. Board members are limited to three terms. The SFMTA Board of Directors is responsible for, among other things, at its inception, the SFMTAs Director of Transportation was Michael T. Burns. On July 15,2005 he left the SFMTA for a position with Santa Clara VTA, ford, Sr. previously the general manager and CEO of MARTA in Atlanta, took over as the new executive director. Johnson would take over as acting director until a permanent replacement was selected by the SFMTA Board. The board selected Edward D. Reiskin, the head of the San Francisco Department of Public Works, as the permanent executive director, the first chair of the SFMTA Board of Directors was H. Welton Flynn, he was succeeded by Cleopatra Vaughns. When Vaughns left the board, James McCray, Jr. was elected chairman, like two of his then-colleagues, McCray previously served on the Parking and Traffic Commission, which was abolished when the department merged into the SFMTA. The Board of Supervisors rejected Stern by a 7–4 vote on September 27,2005, Stern was an official with the International Brotherhood of Electrical Workers. Proposition E also established a 15-member SFMTA Citizens Advisory Council which must review the agencys budget, the mayor appoints four members of the SFMTA Citizens Advisory Council and each member of the Board of Supervisors appoints one. Proposition E allowed for the SFMTA to take over the functions of the Taxicab Commission, in 2009, the agency did so, as a result of legislation passed by the Board of Supervisors and signed by the mayor. In November 2005, the voters of San Francisco rejected, by a margin of 35%–65%, in November 2016 San Francisco voters rejected by 45%–55% a second ballot measure that would have split appointments between the mayor and the Board of Supervisors. The measure would also have made it easier for the supervisors to reject the SFMTA budget. In November 2016, The SFMTA was hit by hackers, using ransomware, demanding $70,000 in bitcoins, with fare machines reading “OUT OF SERVICE”, in February 2006, the MTA Board adopted a resolution adding CEO to the title. When Edward D. Reiskin took office in 2011, he opted to use only the official title. * Although the city charter specifies that the MTA Board shall have a chair, Flynn, Vaughns, McCray, and Nolan have all opted for the style chairman

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

Standard gauge
–
The standard gauge is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge, all high-speed rail lines, except those in Russia, Uzbekistan, and Finland, are standard gauge. The distance between the edges of the rails is defined to be 1435 mm except in the United States. It is also called the UIC gauge or UIC track gauge, as railways developed and expanded, one of the key issues was the track gauge to be used. The result was the adoption throughout a large part of the world of a gauge of 1435 mm. In North East England, some lines in colliery areas were 4 ft 8 in. All these lines had been widened to standard gauge by 1846, parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. However, until well into the half of the 19th century, Britain. The American gauges converged as the advantages of equipment interchange became increasingly apparent, notably, all the 5 ft broad gauge track in the South was converted to standard gauge over the course of two days beginning on 31 May 1886. See Track gauge in the United States, snopes categorized this legend as false, but commented that. It is perhaps more fairly labelled as True, but for trivial, the historical tendency to place the wheels of horse-drawn vehicles approximately 5 feet apart probably derives from the width needed to fit a carthorse in between the shafts. Others were 4 ft 4 in or 4 ft 7 1⁄2 in, the English railway pioneer George Stephenson spent much of his early engineering career working for the coal mines of County Durham. He favoured 4 ft 8 in for wagonways in Northumberland and Durham, the Hetton and Springwell wagonways also used this gauge. Stephensons Stockton and Darlington railway was primarily to transport coal from mines near Shildon to the port at Stockton-on-Tees. The initial gauge of 4 ft 8 in was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made to 4 ft 8 1⁄2 in gauge, George Stephenson used the 4 ft 8 1⁄2 in gauge for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830. The success of this led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Monkland and Kirkintilloch Railway, authorised 1824 and opened 1825, used 4 ft 6 in, Dundee and Newtyle Railway, authorised 1829 and opened 1831, used 4 ft 6 1⁄2 in

3 ft 6 in gauge railways
–
Railways with a track gauge of 3 ft 6 in/1,067 mm were first constructed as horse-drawn wagonways. From the mid-nineteenth century, the 3 ft 6 in gauge became widespread in the British Empire, there are approximately 112,000 kilometres of 1,067 mm gauge track in the world. 1795 One of the first railways to use 3 ft 6 in gauge was the Little Eaton Gangway in England, other 3 ft 6 in gauge wagonways in England and Wales were also built in the early nineteenth century. 1862 In 1862 the Norwegian engineer Carl Abraham Pihl constructed the first 3 ft 6 in gauge railway in Norway,1865 In 1865 the Queensland Railways were constructed. Its 3 ft 6 in gauge was promoted by the Irish engineer Abraham Fitzgibbon,1868 In 1868 Charles Fox asks civil engineer Edmund Wragge to survey a 3 ft 6 in railway in Costa Rica. 1871 In 1871 the Canadian Toronto, Grey and Bruce Railway,1872 In January 1872 Robert Fairlie advocated the use of 3 ft 6 in gauge in his book Railways Or No Railways, Narrow Gauge, Economy with Efficiency v. Broad Gauge, Costliness with Extravagance. 1872 also saw the opening of the first 3 ft 6 in gauge railway in Japan,1873 On 1 January 1873, the first 3 ft 6 in gauge railway was opened in New Zealand, constructed by the British firm John Brogden and Sons. Earlier built 4 ft 8 1⁄2 in and broad gauge railways were converted to the narrower gauge. Also in 1873 the Cape Colony adopted the 3 ft 6 in gauge, after conducting several studies in southern Europe, the Molteno Government selected the gauge as being the most economically suited for traversing steep mountain ranges. Beginning in 1873, under supervision of Railway engineer of the Colony William Brounger, the Cape Government Railways rapidly expanded and the gauge became the standard for southern Africa. 1876 Natal also converted its short 10 kilometres long Durban network from 4 ft 8 1⁄2 in broad gauge prior to commencing with construction of a network across the colony in 1876. Other new railways in Southern Africa, notably Mozambique, Bechuanaland, after 1876 In the late nineteenth and early twentieth century numerous 3 ft 6 in gauge tram systems were built in the United Kingdom and the Netherlands. In Sweden, the gauge was nicknamed Blekinge gauge, as most of the railways in the province of Blekinge had this gauge. An alternate name for this gauge, Cape gauge, is named after the Cape Colony in what is now South Africa, the term Cape Gauge is used in other languages, such as the Dutch kaapspoor, German Kapspur, Norwegian kappspor and French voie cape. After metrication in the 1960s, the gauge was referred to in official South African Railways publications as 1065 mm instead of 1067 mm, the gauge is sometimes referred to as CAP gauge, after C. A. The gauge name Colonial Gauge was used in New Zealand, in Australia the imperial term 3 foot 6 inch is used. In some Australian publications the term medium gauge is also used, in Japan 1,067 mm gauge is referred to as kyōki, which directly translates as narrow gauge.

Minimum railway curve radius
–
The minimum railway curve radius is the shortest allowable design radius for railway tracks under a particular set of conditions. It has an important bearing on costs and operating costs and, in combination with superelevation in the case of train tracks. Minimum radius of curve is one parameter in the design of vehicles as well as trams. Monorails and guideways are also subject to minimum radii, the first proper railway was the Liverpool and Manchester Railway which opened in 1830. Like the trams that had preceded it over a hundred years, among other reasons for the gentle curves were the lack of strength of the track, which might have overturned if the curves were too sharp causing derailments. There was no signalling at this time, so drivers had to be able to see ahead to avoid collisions with previous trains, the gentler the curves, the longer the visibility. The earliest rails were made in lengths of wrought iron. Minimum curve radii for railroads are governed by the speed operated, for handling of long freight trains, a minimum 717-foot radius is preferred. The sharpest curves tend to be on the narrowest of narrow gauge railways, as the need for more powerful locomotives grew, the need for more driving wheels on a longer, fixed wheelbase grew too. But long wheel bases are unfriendly to sharp curves, various types of articulated locomotives were devised to avoid having to operate multiple locomotives with multiple crews. More recent diesel and electric locomotives do not have a wheelbase problem and this is particularly true of the European buffer and chain couplers, where the buffers extend the profile of the railcar body. For a line with maximum speed 60 km/h, buffer-and-chain couplings reduce the radius to around 200 m. A long heavy freight train, especially those with wagons of mixed loading, may struggle on sharp curves, common solutions include, marshalling light and empty wagons at rear of train intermediate locomotives, including remotely controlled ones. Easing curves reduced speeds reduced cant, at the expense of fast passenger trains, equalizing wagon loading better driver training driving controls that display drawgear forces. And c2013 Electronically Controlled Pneumatic brakes, a similar problem occurs with harsh changes in gradients. To counter this, a cant is used, ideally the train should be tilted such that resultant force acts straight down through the bottom of the train, so the wheels, track, train and passengers feel little or no sideways force. Some trains are capable of tilting to enhance this effect for passenger comfort, because freight and passenger trains tend to move at different speeds and weigh dramatically different, a cant cannot be ideal for both types of rail traffic. The relationship between speed and tilt can be calculated mathematically, the values used when building high-speed railways vary, and depend on desired wear and safety levels

Railway electrification system
–
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure, selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas, some electric locomotives can switch to different supply voltages to allow flexibility in operation, Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network, some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own lines, switches and transformers. Power is supplied to moving trains with a continuous conductor running along the track usually takes one of two forms. The first is a line or catenary wire suspended from poles or towers along the track or from structure or tunnel ceilings. Locomotives or multiple units pick up power from the wire with pantographs on their roofs that press a conductive strip against it with a spring or air pressure. Examples are described later in this article, the second is a third rail mounted at track level and contacted by a sliding pickup shoe. Both overhead wire and third-rail systems usually use the rails as the return conductor. In comparison to the alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions. Electric locomotives are usually quieter, more powerful, and more responsive and they have no local emissions, an important advantage in tunnels and urban areas. Different regions may use different supply voltages and frequencies, complicating through service, the limited clearances available under catenaries may preclude efficient double-stack container service. Possible lethal electric current due to risk of contact with high-voltage contact wires, overhead wires are safer than third rails, but they are often considered unsightly. These are independent of the system used, so that. The permissible range of voltages allowed for the voltages is as stated in standards BS EN50163. These take into account the number of trains drawing current and their distance from the substation, railways must operate at variable speeds. Until the mid 1980s this was only practical with the brush-type DC motor, since such conversion was not well developed in the late 19th century and early 20th century, most early electrified railways used DC and many still do, particularly rapid transit and trams

Overhead line
–
An overhead line or overhead wire is used to transmit electrical energy to trams, trolleybuses, or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks, the feeder stations are usually fed from a high-voltage electrical grid. Electric trains that collect their current from overhead lines use a device such as a pantograph and it presses against the underside of the lowest overhead wire, the contact wire. Current collectors are electrically conductive and allow current to flow through to the train or tram, non-electric locomotives may pass along these tracks without affecting the overhead line, although there may be difficulties with overhead clearance. Alternative electrical power transmission schemes for trains include third rail, ground-level power supply, batteries and this article does not cover regenerative braking, where the traction motors act as generators to retard movement and return power to the overhead. To achieve good high-speed current collection, it is necessary to keep the wire geometry within defined limits. This is usually achieved by supporting the wire from a second wire known as the messenger wire or catenary. This wire approximates the path of a wire strung between two points, a catenary curve, thus the use of catenary to describe this wire or sometimes the whole system. This wire is attached to the wire at regular intervals by vertical wires known as droppers or drop wires. It is supported regularly at structures, by a pulley, link, the whole system is then subjected to a mechanical tension. As the contact wire makes contact with the pantograph, the insert on top of the pantograph is worn down. The straight wire between supports will cause the wire to cross over the whole surface of the pantograph as the train travels around the curve, causing uniform wear. On straight track, the wire is zigzagged slightly to the left. The movement of the wire across the head of the pantograph is called the sweep. The zigzagging of the line is not required for trolley poles. Depot areas tend to have only a wire and are known as simple equipment or trolley wire. When overhead line systems were first conceived, good current collection was only at low speeds. Compound equipment - uses a second wire, known as the auxiliary

Volt
–
The volt is the derived unit for electric potential, electric potential difference, and electromotive force. One volt is defined as the difference in potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. It is also equal to the difference between two parallel, infinite planes spaced 1 meter apart that create an electric field of 1 newton per coulomb. Additionally, it is the difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can also be expressed as amperes times ohms, watts per ampere, or joules per coulomb, for the Josephson constant, KJ = 2e/h, the conventional value KJ-90 is used, K J-90 =0.4835979 GHz μ V. This standard is typically realized using an array of several thousand or tens of thousands of junctions. Empirically, several experiments have shown that the method is independent of device design, material, measurement setup, etc. in the water-flow analogy sometimes used to explain electric circuits by comparing them with water-filled pipes, voltage is likened to difference in water pressure. Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure. A resistor would be a reduced diameter somewhere in the piping, the relationship between voltage and current is defined by Ohms Law. Ohms Law is analogous to the Hagen–Poiseuille equation, as both are linear models relating flux and potential in their respective systems, the voltage produced by each electrochemical cell in a battery is determined by the chemistry of that cell. Cells can be combined in series for multiples of that voltage, mechanical generators can usually be constructed to any voltage in a range of feasibility. High-voltage electric power lines,110 kV and up Lightning, Varies greatly. Volta had determined that the most effective pair of metals to produce electricity was zinc. In 1861, Latimer Clark and Sir Charles Bright coined the name volt for the unit of resistance, by 1873, the British Association for the Advancement of Science had defined the volt, ohm, and farad. In 1881, the International Electrical Congress, now the International Electrotechnical Commission and they made the volt equal to 108 cgs units of voltage, the cgs system at the time being the customary system of units in science. At that time, the volt was defined as the difference across a conductor when a current of one ampere dissipates one watt of power. The international volt was defined in 1893 as 1/1.434 of the emf of a Clark cell and this definition was abandoned in 1908 in favor of a definition based on the international ohm and international ampere until the entire set of reproducible units was abandoned in 1948. Prior to the development of the Josephson junction voltage standard, the volt was maintained in laboratories using specially constructed batteries called standard cells

Direct current
–
Direct current is a flow of electrical charge carriers that always takes place in the same direction. The current need not always have the magnitude, but if it is to be defined as dc. This contrasts with alternating current which varies the direction of flow, sources of direct current include power supplies, electrochemical cells and batteries, and photovoltaic cells and panels. The intensity, or amplitude, of a direct current might fluctuate with time, in some such cases the dc has an ac component superimposed on it. An example of this is the output of a cell that receives a modulated light communications signal. A source of dc is sometimes called a dc generator, batteries and various other sources of dc produce a constant voltage. This is called pure dc and can be represented by a straight, the peak and effective values are the same. The peak to peak value is zero because the instantaneous amplitude never changes, in some instances the value of a dc voltage pulsates or oscillates rapidly with time, in a manner similar to the changes in an ac wave. The unfiltered output of a wave or a full wave rectifier. In 1820, Hans Christian Orsted discovered that electrical current creates a magnetic field and this discovery made scientists relate magnetism to the electric phenomena. In 1879, Thomas Edison invented the light bulb. He improved a 50-year-old idea using lower current electricity, a vacuum inside the globe and a small carbonized filament. At that time, the idea of lightning was not new. Edison not only invented an incandescent electric light, but an electric lighting system contained all the necessary elements to make the incandescent light safe, economical. Prior to 1879, direct current electricity had been used in lighting for the outdoors and it was in the 1880s when the modern electric utility industry began. It was an evolution from street lighting systems and from gas and it was located in Lower Manhattan, on Pearl Street. This station provided light and electricity to customers in a one square mile range, the station was called Thomas Edisons Pearl Street Electricity Generating Station. This station introduced four elements of an electric utility system, Efficient distribution, competitive price, reliable central generation

Public transit
–
Public transport modes include city buses, trolleybuses, trams and passenger trains, rapid transit and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail, high-speed rail networks are being developed in many parts of the world. Most public transport runs to a timetable, with the most frequent services running to a headway. Share taxis offer services in many parts of the world. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service, there are distinct differences in urban public transit between Asia, North America, and Europe. In Asia, mass transit operations are run by profit-driven privately owned and publicly traded mass transit. In North America, mass transit operations are run by municipal transit authorities. In Europe, mass transit operations are run by both state-owned and private companies. Public transport services can be profit-driven by use of pay-by-the-distance fares or funded by government subsidies in which flat rate fares are charged to each passenger. Services can be profitable through high ridership numbers and high farebox recovery ratios, or can be regulated. Fully subsidized, zero-fare services operate in some towns and cities, for geographical, historical and economic reasons, there are differences internationally regarding use and extent of public transport. It has 3,400 members from 92 countries, conveyances designed for public hire are as old as the first ferries, and the earliest public transport was water transport, on land people walked or rode an animal. Ferries appear in Greek mythology—corpses in ancient Greece were buried with a coin underneath their tongue to pay the ferryman Charon to take them to Hades, the omnibus was introduced to London in July 1829. The first passenger railway opened in 1806, it ran between Swansea and Mumbles in southwest Wales in the United Kingdom. In 1825 George Stephenson built the Locomotion for the Stockton and Darlington Railway in northeast England, the usability of different types of public transport, and its overall appeal, can be measured by seven criteria, although they overlap somewhat. These are speed, comfort, safety, cost, proximity, speed is calculated from total journey time including transfers. Proximity means how far passengers have to walk or otherwise travel before they can begin the public transport leg of their journey, timeliness is how long they have to wait for the vehicle. Directness records how far a journey using public transport deviates from the shortest route, an airline provides scheduled service with aircraft between airports

San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Bay Area Rapid Transit

Bay Area Rapid Transit is a public transportation system serving the San Francisco Bay Area. The rapid transit elevated and subway system connects San Francisco with cities in Alameda, Contra Costa, BART operates 5 routes on 104 miles of track connecting 45 stations, plus a 3. 2-mile automated guideway transit line to the Oakland International Airport which adds an additional station. A spur line in eastern Contra Costa County will utilize other rail technologies, with an average of 433,000 weekday passengers and 128.5 million annual passengers in fiscal year 2016, BART is the fifth-busiest heavy rail rapid transit system in the United States. The systems acronym is pronounced Bart, like the name, BART is operated by the San Francisco Bay Area Rapid Transit District, formed in 1957. As of 2017, it is being expanded to San Jose with the consecutive Warm Springs, some of the Bay Area Rapid Transit Systems current coverage area was once served by an electrified streetcar and suburban train system called the Key System. This early 20th-century system once had regular trans-bay traffic across the deck of the Bay Bridge. By the mid-1950s, that system had been dismantled in favor of highway travel, a new rapid-transit system was proposed to take the place of the Key System during the late 1940s, and formal planning for it began in the 1950s. Some funding was secured for the BART system in 1959, passenger service began on September 11,1972, initially just between MacArthur and Fremont. All nine Bay Area counties were involved in the planning and envisioned to be connected by BART, before the system began revenue service, serious problems in the design and operation of the Automatic Train Control system were observed. Three engineers working for BART, Max Blankenzee, Robert Bruder, BART management was dismissive of their concerns, so the three took the issue to the board of directors. All but two of the directors voted in February 1972 to support management and reject the safety concerns, management retaliated against the engineers, firing them in March 1972. The IEEE later filed the first amicus brief in its history to support the engineers. The California Society of Professional Engineers reported to the California State Senate in June 1972 that there were serious safety risks with the ATC. Legislative analyst A. Alan Post, opened an investigation immediately, an ATC failure caused the train to run off the end of the elevated track and crash to the ground, injuring four people on-board, and drawing national and international attention. The “Fremont Flyer” led to a redesign of the train controls. The California State Public Utilities Commission imposed stringent oversight over train operations, the legislative analyst issued the first of three “Post Reports” in November 1972. The report was “sharply critical” of BART, finding that the ATC system was unreliable, the ATC program was mismanaged, and “no solution was in sight. ”The report accused BART of paying excessive fees for engineering services. BART’s general manager called the indictment of safety in the Post Report “not only disappointing, telephone calls were placed manually between stations, instead

Caltrain is a California commuter rail line on the San Francisco Peninsula and in the Santa Clara Valley. The northern terminus of the line is in San Francisco at 4th, extra trains were often run for special events held in AT&T Park in San Francisco, Stanford Stadium in Palo Alto, and SAP Center in San Jose. Caltrain operates 92 weekday trains,6 of which are extended to Gilroy, weekday ridership in February 2016 averaged 62,416, up 83% since 2010. Caltrain is governed by the Peninsula Corridor Joint Powers Board which consists of agencies from the three counties served by Caltrain, San Francisco, San Mateo and Santa Clara, each member agency has three representatives on a nine-member Board of Directors. The member agencies are the City and County of San Francisco, SamTrans, Caltrain has 29 regular stops, one football-only stop, and two weekend-only stops. As of October 2012 Caltrain runs 92 weekday trains,36 Saturday, the original commuter railroad built in 1863 was the San Francisco and San Jose Rail Road, it was purchased by Southern Pacific in 1870. Southern Pacific double-tracked the line in 1904 and rerouted it via Bayshore, after 1945, ridership declined with the rise in automobile use, in 1977 SP petitioned the state Public Utilities Commission to discontinue the commute operation because of ongoing losses. To preserve the service, in 1980 Caltrans contracted with SP. Caltrans purchased new locomotives and rolling stock, replacing SP equipment in 1985, Caltrans also upgraded stations, added shuttle buses to nearby employers, and dubbed the operation CalTrain. The Peninsula Corridor Joint Powers Board was formed in 1987 to manage the line, subsequently, San Mateo and Santa Clara Counties commissioned Earth Metrics, Inc. to prepare an Environmental Impact Report on right-of-way acquisition and expansion of operations. With state and local funding, the PCJPB bought the right of way between San Francisco and San Jose from SP in 1991. The following year, PCJPB took responsibility for CalTrain operations and selected Amtrak as the contract operator, PCJPB extended the CalTrain service from San Jose to Gilroy, connecting to VTA Light Rail at Tamien Station in San Jose. In July 1995 CalTrain became accessible to passengers in wheelchairs, five months later, CalTrain increased the bicycle limit to 24 per train, making the service attractive to commuters in bicycle-friendly cities such as San Francisco and Palo Alto. In July 1997 the current logo was adopted, and the name became Caltrain. A year later, VTA extended its rail service from north Santa Clara to the Mountain View Caltrain station. In June 2003, a connection for the Bay Area Rapid Transit. In 2006, Caltrain announced that wireless internet access would be available on trains at no additional charge, Caltrain invested more than $1 million in researching and testing WiFi in 2006. Caltrain still hopes to offer the service eventually as part of a comprehensive communication package

SamTrans is a public transport agency in and around San Mateo, California, in the San Francisco Bay Area. It provides bus service throughout San Mateo County and into portions of San Francisco, SamTrans also operates commuter shuttles to BART stations and community shuttles. Service is largely concentrated on the east side of the Santa Cruz Mountains, SamTrans is constituted as a special district under California state law. The district was established in 1976 and consolidated eleven different municipal bus systems serving the county, one year later, SamTrans began operation of mainline bus service to San Francisco. In addition to fixed bus and paratransit operations, the district participates in the administration of the San Jose-San Francisco commuter rail line Caltrain. Most routes provide connecting service to BART, Caltrain, or both, there is also regular scheduled service to San Francisco International Airport and Transbay Terminal in downtown San Francisco. Unlike most large transit operators in the Bay Area, SamTrans outsources to private contractors the operation of a number of its routes, the current contract operator for Peninsula mainline, Coastside and paratransit services is MV Transportation. SamTrans previously operated special service for a couple of Bay Area events such as San Francisco 49ers home football games, since SamTrans reorganized its bus routes in August 1999, it adopted a new route designation system to identify service types, geographical coverage, and connections to rail services. Express bus routes are designated by a letter and X, in December 2009, seven express routes were eliminated due to budget constraints, route KX is the only remaining express route. Local routes have two or three digits or a special designation. Most of these routes do not connect with rail and operate on school days, SamTrans offers bus tokens for adult and youth local fares, US$16 and US$10 respectively, in packages of ten. Multiple tokens or combinations of tokens and cash are accepted for journeys requiring higher fares, tokens are promoted as being easier to handle than cash, and also include discounts. For example, a package of tokens includes 2 free rides assuming the others are worth $2 each or $1.25 each, SamTrans does not provide transfers but offers a Day Pass which allows unlimited rides on local routes and a credit on higher-cost routes. The cost of the Day Pass is three times the one-way fare on the routes for adults, youth, and seniors/disabled/Medicare cardholders. Clipper cards come in four varieties, adult, youth, senior, adult Clipper cards may be obtained from a wide variety of vendors, but youth, senior and disabled Clipper cards must be obtained from SamTrans or another Bay Area transit agency. Each Clipper card contains some sort of stored value and the history of recent trips using the card, Clipper cards generally confer an approximately 10% discount relative to cash fares. With the exception of youth summer passes, all SamTrans monthly passes must be loaded onto a Clipper card, youth, senior and disabled monthly passes may only be loaded onto a corresponding Clipper card obtained from SamTrans or another Bay Area transit agency. To ride SamTrans with Clipper card, the card must be tagged by the Clipper card reader installed at the front of the bus near the farebox

Golden Gate Transit is a public transportation system serving the North Bay region of the San Francisco Bay Area in California, United States. It primarily serves Marin and Sonoma counties, and also limited service to San Francisco. Funding for cross-bridge Transbay bus service is subsidized by Golden Gate Bridge tolls in addition to traditional federal. GGT provides some bus service within Marin County under contract with Marin Transit, Golden Gate Transit is constituted as a special district under California State Law, as evidenced by Assembly Bill 584, creating the Golden Gate Bridge, Highway and Transportation District. Napa, Mendocino, and Del Norte,1 Director each, Golden Gate Transit has alleviated congestion on the Golden Gate Bridge and along the Golden Gate Corridor since 1972. A history of service is listed below, with average annual increase in traffic of 70% over 30 years, the Bridge was close to reaching its saturation point. As congestion mounted, several studies were undertaken to identify alternate means of travel between Marin County and San Francisco, the San Francisco-Marin Crossings report of May 1967 looked at the possibility of building another bridge. The District also considered adding a second deck to the Bridge, the Marin County Transit District considered taking over the existing Greyhound system as a commute service to San Francisco. Greyhound provided transit between Marin County and San Francisco at the time and it was unprofitable, so Greyhound management planned to abandon it. As air pollution increased and congestion took its toll on commuters, San Francisco, Marin, the plan called for bus service from neighborhoods in Marin and Sonoma Counties to the San Francisco Financial District and Civic Center areas. By the late 1960s, the Bridge was operating at capacity during the commute period. Original Bridge construction bonds were due to be retired in 1971, and this included any and all forms of transit, including buses and ferries. The word Transportation was added to the Districts name at that time to indicate its new commitment to public transportation, the legislature did not give the District the authority to levy taxes. Legislation also restricted the use of Bridge tolls to support only regional transit services, on 10 December 1971, Assembly Bill 919 was passed, requiring the District to develop a long-range transportation program for the corridor. Bus service began in December 1970 when the District initiated a service to the Sausalito Ferry Terminal using 5 buses leased from Greyhound on 4 bus routes driven by 4 drivers. The District soon bought 132 buses to start its operations, in September 1971, the District hired 30 experienced Greyhound drivers to operate the new bus service. GGT began operating bus service in December 1971 under contract with MCTD. The initial GGT system was operated with 152 buses and facilities in Novato and Santa Rosa, in 1974, the District opened its permanent bus administration and central maintenance facility at 1011 Andersen Drive in San Rafael

AC Transit is an Oakland-based public transit agency serving the western portions of Alameda and Contra Costa counties in the East Bay of the San Francisco Bay Area. AC Transit also operates Transbay routes across San Francisco Bay to San Francisco and selected areas in San Mateo, AC Transit is constituted as a special district under California law. It is governed by seven elected members and it is not a part of or under the control of Alameda or Contra Costa counties or any local jurisdictions. Buses operate out of three operating divisions, Emeryville, East Oakland, and Hayward, the Operations Control Center is located in Emeryville. The Richmond operating division closed in 2011, the District is the public successor to the privately owned Key System. The Districts bus lines also serve parts of some other East Bay communities, including Milpitas, Pinole, most routes connect with regional train service, primarily BART, in addition to ACE and Amtrak, including the Capitol Corridor. While most AC Transit service consists of lines throughout the East Bay. Most of these run across the San Francisco–Oakland Bay Bridge to connect communities as distant as El Sobrante, Bus service is also provided across the San Mateo and Dumbarton bridges to the south. AC Transits primary hubs include BART stations, major shopping centers, and points of interest, most routes serve and/or terminate at BART stations, providing convenience for transit users. The hubs include, See also AC Transits page on fares and passes or AC Transits page on bus fares, on July 1,2014, AC Transit introduced a Day Pass, designed for customers taking more than two local buses in a day. The pass is good for unlimited rides on local routes from 3,01 a. m. to 3,00 a. m. Customers can obtain a Day Pass in one of two ways, Using Clipper, Customers keep cash value on their card. Once fares equalling the Day Pass price have been deducted, the Day Pass automatically activates, on subsequent rides, the card is tagged but no additional fare is deducted. On-Board, Customers deposit the amount in the farebox and request a Day Pass from the bus operator. On subsequent rides, the pass is swiped at the farebox, AC Transit fares are structured to promote the use of Clipper. Not only are local bus rides cheaper, but certain interagency transfers and day passes are easier to obtain, monthly passes are only available on Clipper. Local BART-to-bus transfer, $0.25 cash discount to and from BART with paper transfer issued at BART, applied as $0.50 Clipper discount on bus trip away from BART only. To transfer from AC Transit to another bus agency without Clipper, to transfer from another bus agency to AC Transit without Clipper, ask the other bus driver for a transfer. Notes, All fares are in USD,1 Issued upon request when full price is paid

Trolley bus
–
A trolleybus is an electric bus that draws power from overhead wires using spring-loaded trolley poles. Two wires and poles are required to complete the electrical circuit and this differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there have been, currently, around 300 trolleybus systems are in operation, in cities and towns in 43 countries. Altogether, more than 800 trolleybus systems have existed, but not more than about 400 concurrently, the trolleybus dates back to 29 April 1882, when Dr. Ernst Werner Siemens demonstrated his Elektromote in a Berlin suburb. This experiment continued until 13 June 1882, after there were few developments in Europe. In 1899, another vehicle which could run either on or off rails was demonstrated in Berlin, routes followed in Eberswalde and Fontainebleau. Max Schiemann on 10 July 1901 opened the worlds fourth passenger-carrying trolleybus system, although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system. In the early days there were a few methods of current collection. The Cédès-Stoll system was operated near Dresden between 1902 and 1904, and in Vienna, the Lloyd-Köhler or Bremen system was tried out in Bremen, and the Cantono Frigerio system was demonstrated near Milan. Throughout the period, trackless freight systems and electric canal boats were also built, Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911. Apparently, though it was opened on 20 June, the public was not admitted to the Bradford route until the 24th, Bradford was also the last to operate trolleybuses in the UK, the system closing on 26 March 1972. The last rear-entrance trolleybus in Britain was also in Bradford and is now owned by the Bradford Trolleybus Association, birmingham was the first to replace a tram route with trolleybuses, while Wolverhampton, under the direction of Charles Owen Silvers, became world-famous for its trolleybus designs. There were 50 trolleybus systems in the UK, Londons being the largest, by the time trolleybuses arrived in Britain in 1911, the Schiemann system was well established and was the most common, although the Cédès-Stoll system was tried in West Ham and in Keighley. Smaller trackless trolley systems were built in the US early as well, the trackless trolley was often seen as an interim step, leading to streetcars. Buses and trolleybuses in particular were seen as entry systems that could later be upgraded to rail as appropriate, some trolleybus lines in the United States came into existence when a trolley or tram route did not have sufficient ridership to warrant track maintenance or reconstruction. In a similar manner, a proposed tram scheme in Leeds, worldwide, around 300 cities or metropolitan areas are served by trolleybuses today. See also Trolleybus usage by country, for example, new systems opened in Lecce, Italy, in 2012 and in Malatya, Turkey, in 2015

Muni Metro

Muni Metro is a light rail/streetcar hybrid system serving San Francisco, California, operated by the San Francisco Municipal Railway, a division of the San Francisco Municipal Transportation Agency. With an average ridership of 128,500 passengers as of the fourth quarter of 2014. Muni Metro operates a fleet of 151 light rail vehicles made by Breda, Muni Metro is the modern incarnation of the traditional streetcar system that had served San Francisco since the late 19th century. Recently, the system has undergone expansion, most notably the Third Street Light Rail Project, completed in 2007, other projects, such as the Central Subway, are underway. Muni Metro descended from the traditional streetcar system started on December 28,1912. The first streetcar line, the A Geary, ran from Kearny and Market Streets in the Financial District to Fulton Street, the system slowly expanded, opening the Twin Peaks Tunnel in 1917, allowing streetcars to run to the southwestern quadrant of the city. By 1921, the city was operating 304 miles of trolley lines and 25 miles of cable car lines. The last line to service before 2007 was the N Judah. However, five heavily used streetcar lines traveled for at least part of their routes through tunnels or otherwise reserved right-of-way, as a result, these lines, running PCC streetcars, continued in operation. The new tunnel would be connected to the existing Twin Peaks Tunnel, the new underground stations would feature high platforms, and the older stations would be retrofitted with the same, which meant that the PCCs could not be used in them. Hence, a fleet of new rail vehicles was ordered from Boeing-Vertol. The K and M lines were extended to Balboa Park during this time, on February 18,1980, the Muni Metro was officially inaugurated, with weekday N line service in the subway. The Metro service was implemented in phases, and the subway was served only on weekdays until 1982. The K Ingleside line began using the Metro subway on weekdays on June 11,1980, the L Taraval and M Ocean View lines on December 17,1980, and lastly the J Church line on June 17,1981. Meanwhile, weekend service on all five lines continued to use PCC cars operating on the surface of Market Street through to the Transbay Terminal, finally, on November 20,1982, the Muni Metro subway began operating seven days a week. At the time, there were no plans to revive any service on the surface of Market Street or return PCCs to regular running. However, tracks were rehabilitated for the 1983 Historic Trolley Festival, Muni criticism had been something of a feature of life in San Francisco, and not without reason. The Boeing trains were sub-par and grew crowded quickly, Muni did take steps to address these problems

San Francisco cable car system
–
The San Francisco cable car system is the worlds last manually operated cable car system. An icon of San Francisco, the car system forms part of the intermodal urban transport network operated by the San Francisco Municipal Railway. Of the 23 lines established between 1873 and 1890, only three remain, two routes from downtown near Union Square to Fishermans Wharf, and a route along California Street. While the cable cars are used to an extent by commuters. They are among the most significant tourist attractions in the city, along with Alcatraz Island, the Golden Gate Bridge, the cable cars are listed on the National Register of Historic Places. The cable cars are not to be confused with San Franciscos heritage streetcars, which operate on Market Street, the first successful cable-operated street railway was the Clay Street Hill Railroad, which opened on August 2,1873. The promoter of the line was Hallidie, and the engineer was William Eppelsheimer, the line involved the use of grip cars, which carried the grip that engaged with the cable, towing trailer cars, the design was the first to use grips. The term grip became synonymous with the operator, the line started regular service on September 1,1873, and its success led it to become the template for other cable car transit systems. It was a success, and Hallidies patents were enforced on other cable car promoters. Accounts differ as to exactly how involved Hallidie was in the inception of the line, the next cable car line to open was the Sutter Street Railway, which converted from horse operation in 1877. This line introduced the side grip, and lever operation, both designed by Henry Casebolt and his assistant Asa Hovey, and patented by Henry Casebolt. This idea was brought about because Casebolt did not want to pay Hallidie royalties of $50,000 a year for use of his patent, the side grip allowed cable cars to cross at intersections. In 1878, Leland Stanford opened his California Street Cable Railroad and this companys first line was on California Street and is the oldest cable car line still in operation. In 1880, the Geary Street, Park & Ocean Railway began operation, the Presidio and Ferries Railway followed two years later, and was the first cable company to include curves on its routes. The curves were let-go curves, where the car drops the cable, in 1883, the Market Street Cable Railway opened its first line. This company was controlled by the Southern Pacific Railroad and was to grow to become San Franciscos largest cable car operator. At its peak, it operated five lines all of which converged into Market Street to a terminus at the Ferry Building, during rush hours, cars left that terminus every 15 seconds. In 1888, the Ferries and Cliff House Railway opened its initial two-line system, the Powell-Mason line is still operated on the same route today, their other route was the Powell-Washington-Jackson line, stretches of which are used by todays Powell-Hyde line

Tram
–
A tram is a rail vehicle which runs on tracks along public urban streets, and also sometimes on a segregated right of way. The lines or networks operated by tramcars are called tramways, Tramways powered by electricity, the most common type historically, were once called electric street railways. However, trams were used in urban areas before the universal adoption of electrification. Tram lines may run between cities and/or towns, and/or partially grade-separated even in the cities. Very occasionally, trams also carry freight, Tram vehicles are usually lighter and shorter than conventional trains and rapid transit trains, but the size of trams is rapidly increasing. Some trams may also run on railway tracks, a tramway may be upgraded to a light rail or a rapid transit line. For all these reasons, the differences between the modes of rail transportation are often indistinct. In the United States, the tram has sometimes been used for rubber-tired trackless trains. Today, most trams use electrical power, usually fed by a pantograph, in some cases by a sliding shoe on a third rail. If necessary, they may have dual power systems — electricity in city streets, trams are now included in the wider term light rail, which also includes segregated systems. The English terms tram and tramway are derived from the Scots word tram, referring respectively to a type of truck used in coal mines and the tracks on which they ran. The word tram probably derived from Middle Flemish trame, a Romanesque word meaning the beam or shaft of a barrow or sledge, the identical word la trame with the meaning crossbeam is also used in the French language. The word Tram-car is attested from 1873, although the terms tram and tramway have been adopted by many languages, they are not used universally in English, North Americans prefer streetcar, trolley, or trolleycar. The term streetcar is first recorded in 1840, and originally referred to horsecars, when electrification came, Americans began to speak of trolleycars or later, trolleys. The troller design frequently fell off the wires, and was replaced by other more reliable devices. The terms trolley pole and trolley wheel both derive from the troller, Modern trams often have an overhead pantograph mechanical linkage to connect to power, abandoning the trolley pole altogether. Conventional diesel tourist buses decorated to look like streetcars are sometimes called trolleys in the US, the term may also apply to an aerial ropeway, e. g. the Roosevelt Island Tramway. Over time, the trolley has fallen into informal use

E Embarcadero
–
The E Embarcadero is a light rail line that is the San Francisco Municipal Railways second heritage streetcar line in San Francisco, California. Trial service first ran during the Sunday Streets events on The Embarcadero in 2008, the line initially ran on weekends only, but expanded to weeklong service in late April 2016. The initial routing of the line is identical to the 32 Embarcadero bus line. Since there is no loop at the Caltrain station, only double-ended streetcars are able to operate on the line until the 19th Street loop is built, in the future, the line may extend northwest past Aquatic Park and through an unused railroad tunnel to Fort Mason. For this reason, existing sidewalk-level stops adjacent to each raised central light-rail stop will be utilized for the E line, for stops north of Market, the new line will use those of the existing F Market & Wharves line. Munis original E streetcar line was the E Union line, running north from the Ferry Building via The Embarcadero to Washington/Jackson streets and this line was discontinued in 1947. Proposals for historic streetcar service along The Embarcadero were first put forward in 1974, and this temporary line was designated E Embarcadero, and it was discontinued when it was replaced in August 1998 by an extension of the N Judah line. In 2007 the new T Third Street line also began operating on this extension, historic streetcar service on The Embarcadero north of Don Chee Way began in March 2000 when the F Market & Wharves line was extended to Fishermans Wharf. The new E Embarcadero line operated on a temporary basis during the 2013 Americas Cup racing, weekend operation officially began on August 1,2015, and weeklong service began on April 23,2016.

F Market
–
The F Market & Wharves line is one of several light rail lines in San Francisco, California. Despite its heritage status, the F Market & Wharves line is an part of Munis intermodal urban transport network, operating at frequent intervals for 20 hours a day. It carries local commuters and tourists alike, linking residential, business, unlike the San Francisco cable car system, standard Muni fares are levied. The streetcar line was discontinued in 1951 and was replaced by the 30-Stockton route, the F-line designation was therefore available for use by the current line, although that service is over a completely different route from the F-line of 1915 to 1951. Market Street is a major artery for the city of San Francisco. In the 1960s construction began on the Market Street Subway, which would carry BARTs trains on its lower level, all streetcar lines currently operating in the subway previously ran on the surface of Market Street, and were eventually diverted into the upper level of the tunnel. This diversion, together with the provision of new rail cars. The diversion of the Market Street streetcar lines into tunnel and the replacement of the existing streetcars with new rail cars was completed by November 1982. However, the trackage on Market Street was retained. In 1982, San Franciscos cable car lines were shut down for almost two years to allow for a major rebuild, to provide an alternative tourist attraction during this period, the San Francisco Historic Trolley Festivals began in 1983. These summertime operations of vintage streetcars on Market Street were a joint project of the San Francisco Chamber of Commerce, the trolley festival route went from the Transbay Terminal at First and Mission Streets to Market, then up the retained Market Street tracks to Duboce Avenue. From there, it followed a temporary streetcar detour built in the 1970s to bypass subway construction under Market, Duboce, Church Street, the Trolley Festival proved so successful it was repeated every year until 1987. In that year, preparation began for the introduction of a permanent F line, after that year’s festival finished, Muni replaced the old Market Street tracks with new ones, restoring tracks to upper Market Street and recreating a line to Castro. Different types of streetcars were evaluated to provide the backbone of the F-line fleet, resulting in the decision to use the PCC car. Fourteen such cars were acquired second-hand from Philadelphia to add to three of Muni’s own retired double-ended PCCs, at that point in history, this was a rare instance in which a streetcar replaced a bus line in operation, rather than the other way around. Ridership exceeded expectation, and the need for extra cars resulted in the acquisition of ten Peter Witt style cars just being retired in the city of Milan, Italy. These cars were built in the 1920s to a once common in North American cities. The Embarcadero is the eastern waterfront roadway of San Francisco, along San Francisco Bay, at one time busy with port and ferry related traffic, it fell into decline as freight transferred to the container terminals of Oakland and the Bay Bridge replaced the ferries
