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

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Caltrain
–
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

Island platform
–
An island platform is a station layout arrangement where a single platform is positioned between two tracks within a railway station, tram stop or transitway interchange. Island platforms are popular on twin-track routes due to pragmatic and cost-effective reasons, an alternative arrangement is to position side platforms on either side of the tracks. The historical use of island platforms depends greatly upon the location, the island platform layout is a popular, cost-effective and practical solution in modern railway systems. Island platforms allow facilities such as escalators, elevators, shops, toilets and this is essential for wheelchair accessible stations. An island platform makes it easier for users and the infirm to change services between tracks. Additionally, an island platform layout eliminates the need to construct a crossover or subway between two platforms, however, island platforms may become overcrowded, especially at busy stations, and this can lead to safety issues such as Clapham Common and Angel on the London Underground. However, for the tracks to diverge around the platform, extra width is required along the right-of-way on each approach to the station. Track centers vary for rail systems throughout the world but are normally 3 to 5 meters, if the island platform is 6 meters wide, the tracks have to slew out by the same distance. While this is not a problem on a new line that is being constructed, in addition, a single island platform makes it quite difficult to have through tracks, which are usually between the local tracks. A common configuration in busy locations on high speed lines is a pair of island platforms, high-speed trains can therefore pass straight through the station, while slow trains pass around the platforms. This arrangement also allows the station to serve as a point where trains can be passed by faster trains. The purpose of this design was to reduce unnecessary passenger congestion at a station with a high volume of passengers. Many of the stations on the Great Central Railway were constructed in this form and this was because the line was planned to connect to a Channel Tunnel. Island platforms are a normal sight on Indian railway stations. Almost all railway stations in India consist of island platforms, in Toronto,29 subway stations use island platforms. A slight disadvantage is that crossovers have to be rather long, in southern New Jersey and Philadelphia, PATCO uses island platforms in all of its 13 stations, to facilitate one-person train operation. Most elevated stations in Singapores Mass Rapid Transit system use island platforms, the exception is Dover MRT Station, which uses side platforms as it is built on an existing rail line. The planned Canberra MRT Station will also use side platforms, as it also be built on an existing rail line

Side platform
–
A side platform is a platform positioned to the side of a pair of tracks at a railway station, tram stop, or transitway. Dual side platform stations, one for direction of travel, is the basic station design used for double-track railway lines. Side platforms may result in a wider overall footprint for the station compared with a platform where a single width of platform can be shared by riders using either track. In some stations, the two platforms are connected by a footbridge running above and over the tracks. While a pair of platforms is often provided on a dual-track line. Where the station is close to a crossing the platforms may either be on the same side of the crossing road or alternatively may be staggered in one of two ways. With the near-side platforms configuration, each platform appears before the intersection, in some situations a single side platform can be served by multiple vehicles simultaneously with a scissors crossing provided to allow access mid-way along its length. Normally, the facilities of the station are located on the Up platform with the other platform accessed from a footbridge. However, in cases the stations main buildings are located on whichever side faces the town or village the station serves. Larger stations may have two platforms with several island platforms in between. Some are in a Spanish solution format, with two platforms and an island platform in between, serving two tracks

22nd Street station (Caltrain)
–
22nd Street is a Caltrain commuter rail station on 22nd Street beneath the I-280 freeway in San Francisco, California. It is the only station in the Caltrain system. The only way for passengers to reach the platforms is by stairway, like all Caltrain stations except San Francisco 4th & King and San Jose Diridon, the station is unstaffed, passengers buy tickets from machines. In Southern Pacific days the station was called 23rd St, Ticket Machines Caltrain 8-Ride Ticket Validators MUNI48 Quintara-24th Street Media related to 22nd Street at Wikimedia Commons Caltrain 22nd Street station page

Tamien Station
–
Tamien Station is an intermodal passenger transportation station served by the Santa Clara Valley Transportation Authority light rail system, two bus routes, and the Caltrain commuter rail line. The station has two distinct elevated rail platforms – one for Caltrain, the other for light rail, each is a center platform with two trackways. The two platforms are connected by a walkway at ground-level that is below the two platforms, currently, Caltrain does not serve this station during the middle of the day on weekdays. On weekends, a Caltrain shuttle bus instead of a train connects Tamien to the San Jose Diridon station, the station is named after the Tamien who were some of the Ohlone, a Native American people. The Caltrain platform is located between Lick Avenue and State Route 87, just north of Alma Avenue, menlo Park, CA, Ballena Press Publication,1994.

Gilroy station
–
Gilroy is a Caltrain station located in Gilroy, California. It is the southernmost terminus on the Caltrain line, and is served during commute hours on weekdays. It is located in Fare Zone 6, Gilroy is a former Southern Pacific Railroad depot that was adopted by the Peninsula Corridor Joint Powers Board. Amtraks Coast Starlight passes through Gilroy between Salinas and San Jose Diridon, but does not stop, once every year, Caltrain operated a special limited-stop train from San Francisco to Gilroy that operated during the weekend of the Gilroy Garlic Festival in Christmas Hill Park. Shuttle buses would take passengers from the Caltrain station to the festival, when weekend service resumed in 2004, Caltrain opted to end the annual Garlic Train. The Golden Gate Railroad Museum chartered weekend trains to Gilroy during the festival for a few years, Caltrain announced that the Garlic Train would resume service for the 2013 Garlic Festival. The Gilroy Rail Station is one of two sites that California High Speed Rail is considering for its Gilroy stop, with the site on lands immediately east of Gilroy Premium Outlets.

Caltrain Express
–
California State Senator Jackie Speier and Caltrain leadership are credited with the idea to provide an express service for Caltrain during a brainstorming session. The funding request for the Caltrain express service was incorporated directly into the Governors budget. CTX was one of the projects recommended by the Metropolitan Transportation Commission under Resolution 3434 in December 2001, CTX officially broke ground during a ceremony held at 4th and King on June 28,2002. At the time, it was the largest capital improvement program for Caltrain, during CTX construction, Caltrain shut down weekend service for two years starting in July 2002 to allow track work. M. and the line only had two intermediate stops, at Hillsdale and Palo Alto. After construction was complete and weekend service resumed in June 2004, during construction, service was also reduced to a single track on Thursday and Friday nights after 9 P. M. By April 2004, Caltrain was showing off the stock it had acquired for Baby Bullet service. The first southbound Baby Bullet left San Francisco with 420 passengers at 7,20 AM, Baby Bullet trains often ran at standing room capacity during the first year. Just prior to the inauguration of Baby Bullet service, Caltrain served an average of 27,000 riders per weekday. One year later, Caltrain ridership had increased by 12%, and by 2014, ten years later, Caltrain ridership had more than doubled to over 60,000 riders per weekday. In addition to having one of the new locomotives named for her, CTX received a Tranny award from the California Transportation Foundation as the Program of the Year for 2004. During the same ceremony, Speier was honored as the Legislator of the Year, Caltrain split the CTX project into two separate phases, based on geographic region. The North CTX extended from San Francisco to Redwood City, the North CTX contract was awarded in April 2002 to the joint venture partnership of Herzog Contracting Corporation and Stacy and Witbeck. Herzog-Stacy-Witbeck also won the South CTX contract, as announced in January 2003, the key elements of CTX were the overtake tracks, high-speed crossovers, and a central traffic control system which collectively allowed a single office to route trains. To support smoother operation at higher sustained speeds, Caltrain also laid down continuous-welded rails, during the CTX project, Caltrain rebuilt the Bayshore station, relocating it slightly south of the prior location to accommodate the north quad track overtake section ending just south of Tunnel #4. A small rail bridge south of Bayshore was built over a creek as part of CTX, Lawrence Station was in the right-of-way planned for the south quad-track overtake section, so Lawrence was rebuilt with new platforms and an under-track pedestrian tunnel. Work at Lawrence was anticipated to be completed by the end of 2003, the Millbrae station also received some upgrades, a third track was added and existing tracks were relocated, requiring Caltrain to demolish the existing platform. Millbrae station updates were scheduled to complete with the opening of the new station in January 2003. CTX added quad-track overtake sections near the cities of Brisbane and Sunnyvale, during the initial design phase, overtakes were also announced for Millbrae and Redwood City

Millbrae station
–
The Millbrae Intermodal Terminal is an at-grade Bay Area Rapid Transit and Caltrain station located in suburban Millbrae, California, in northern San Mateo County. It was expected to support over 30,000 BART trips per day, Millbrae Station is the largest intermodal terminal in the United States west of the Mississippi. It has three tracks for BART and two for Caltrain. An island platform allows a connection between the two systems. A concourse mezzanine is above the platforms, currently two BART tracks and one island platform usually are kept out of regular service, used instead to hold train sets that are also out of service. The station is also a bus transit hub with multiple bus bays served by several SamTrans lines. Millbrae Station has about 2,900 parking spaces, including a parking garage. The Reserved Parking areas cost $2/day from 10am-3pm on weekdays, a free Library-a-Go-Go Peninsula Library System library book vending machine was added in May 2011. The station has daily Caltrain commuter rail service along the line between San Jose and San Francisco. Midday trains are hourly each way, service is frequent during commute hours. Service south of San Jose to Gilroy is limited to three weekday round trips. Passengers who board the train without a ticket are subject to fines of up to $250 plus court fees. Passengers who use the electronic Clipper card to ride the Caltrain must remember to tag on their card prior to boarding, if they board the train without tagging on, they will be subject to the same fines. In addition, Caltrain passengers are charged the maximum one way fare when they tag on prior to boarding the train, if passengers who use the Clipper card forget to tag off when they exit the train, they will be charged the highest cash fare from point of origin. In 2015, construction began on the rail system. If completed as planned, Millbrae would serve as one of one or two stations between San Francisco and San Jose, and would allow high-speed rail passengers to reach SFO via BART. $290 million has been allocated to lengthen the platforms for connection to High Speed Rail, before the Millbrae Intermodal Terminal was built for the BART San Mateo Extension terminus Millbrae had a free Caltrain shuttle bus between the station and San Francisco International Airport. The former Southern Pacific Depot has been listed on the National Register of Historic Places since September 1,1978, in 1985 Caltrain service began at the original Millbrae depot, replacing Southern Pacific trains that had operated along the San Francisco Peninsula since the early 20th century
