H.K. Porter, Inc.
–
Porter, Inc. manufactured light-duty railroad locomotives in the US, starting in 1866. The company became the largest producer of industrial locomotives, and built almost eight thousand of them, the last locomotive was built in 1950, but the company continues to produce industrial equipment to this day. Porter was known for building locomotives that were smaller than those normally used by the larger Class I railroads. The companys locomotives were small enough that they were operated by only one person. Porter built mostly steam locomotives, but they built some powered by gasoline and diesel engines. The largest collection of Porter photographs and information is currently housed in the Kentlein Porter Collection at the A. C, kalmbach Memorial Library in Chattanooga, TN. Many of the 780 builders photos, blueprints and other data were republished in Porter Steam Locomotives. 1866, Henry Kirke Porter formed a partnership with John Y. Smith, the two opened a small machine shop on 28th Street in Pittsburgh, Pennsylvania, and begin repairing and building industrial equipment. They received an order for their first locomotive on March 4,1867 and they went on to build 43 locomotives together, including the Minnetonka. They specialized in four wheeled, saddle tank locomotives for small industrial railroads,1871, Fire broke out in the shop on February 7, destroying twelve locomotives under construction, the shop, and 23 adjacent structures. Total losses were estimated at $200,000, and the partnership was dissolved, Smith formed Smith & Dawson Locomotives, which became National Locomotive Works. Porter formed a partnership with Arthur W. Bell, called Porter, Bell & Co. and they expanded their range to include light passenger engines and small freight engines, primarily for narrow gauge railroads. They built 223 locomotives, until Arthur Bell died in May 1878,1878, Henry K. Porter continued the business on his own, as H. K. He had established a reputation as a builder of rugged, specialized locomotives and he could custom build a locomotive quickly and efficiently, with a system of interchangeable parts, pistons, wheels and boilers in various sizes that can be combined to suit a customers requirements. Some of the designs are kept in stock, and can be ordered literally off the shelf. 1890, Porter built their first compressed-air locomotive, for a mine in Pennsylvania. Air was stored in two tanks, and used to drive the pistons instead of steam and this allowed locomotive use inside mines without the fumes of burning coal, or the dangers of high-pressure steam. Porter went on to build over 400 compressed-air locomotives for use in mines, plants, others built compressed-air locomotives, but by 1900 Porter had captured 90% of the market

Locomotive
–
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. A locomotive has no payload capacity of its own, and its purpose is to move the train along the tracks. In contrast, some trains have self-propelled payload-carrying vehicles and these are not normally considered locomotives, and may be referred to as multiple units, motor coaches or railcars. The use of these vehicles is increasingly common for passenger trains. Traditionally, locomotives pulled trains from the front, however, push-pull operation has become common, where the train may have a locomotive at the front, at the rear, or at each end. Prior to locomotives, the force for railroads had been generated by various lower-technology methods such as human power, horse power. The first successful locomotives were built by Cornish inventor Richard Trevithick, in 1804 his unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in Wales. Although the locomotive hauled a train of 10 long tons of iron and 70 passengers in five wagons over nine miles, the locomotive only ran three trips before it was abandoned. Trevithick built a series of locomotives after the Penydarren experiment, including one which ran at a colliery in Tyneside in northern England, the first commercially successful steam locomotive was Matthew Murrays rack locomotive, Salamanca, built for the narrow gauge Middleton Railway in 1812. This was followed in 1813 by the Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, Puffing Billy is now on display in the Science Museum in London, the oldest locomotive in existence. In 1814 George Stephenson, inspired by the locomotives of Trevithick. He built the Blücher, one of the first successful flanged-wheel adhesion locomotives, Stephenson played a pivotal role in the development and widespread adoption of steam locomotives. His designs improved on the work of the pioneers, in 1825 he built the Locomotion for the Stockton and Darlington Railway, north east England, which became the first public steam railway. In 1829 he built The Rocket which was entered in and won the Rainhill Trials and this success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives used on railways in the United Kingdom, the United States and much of Europe. The first inter city passenger railway, Liverpool and Manchester Railway, opened in 1830, there are a few basic reasons to isolate locomotive train power, as compared to self-propelled vehicles. Maximum utilization of power cars Separate locomotives facilitate movement of costly motive power assets as needed, flexibility Large locomotives can substitute for small locomotives when more power is required, for example, where grades are steeper. As needed, a locomotive can be used for freight duties. Obsolescence cycles Separating motive power from payload-hauling cars enables replacement without affecting the other, to illustrate, locomotives might become obsolete when their associated cars did not, and vice versa

Electric locomotive
–
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or fuel cell. Electricity is used to smoke and take advantage of the high efficiency of electric motors. One advantage of electrification is the lack of pollution from the locomotives, electrification results in higher performance, lower maintenance costs and lower energy costs. Power plants, even if they burn fossil fuels, are far cleaner than mobile sources such as locomotive engines, the power can come from clean or renewable sources, including geothermal power, hydroelectric power, nuclear power, solar power and wind turbines. Electric locomotives are quiet compared to locomotives since there is no engine and exhaust noise. The lack of reciprocating parts means electric locomotives are easier on the track, Electric locomotives are ideal for commuter rail service with frequent stops. They are used on high-speed lines, such as ICE in Germany, Acela in the U. S. Shinkansen in Japan, China Railway High-speed in China, Electric locomotives are used on freight routes with consistently high traffic volumes, or in areas with advanced rail networks. Electric locomotives benefit from the efficiency of electric motors, often above 90%. Additional efficiency can be gained from regenerative braking, which allows energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems provide for regenerative braking. The chief disadvantage of electrification is the cost for infrastructure, overhead lines or third rail, substations, public policy in the U. S. interferes with electrification, higher property taxes are imposed on privately owned rail facilities if they are electrified. In Europe and elsewhere, railway networks are considered part of the transport infrastructure, just like roads, highways and waterways. Operators of the rolling stock pay fees according to rail use and this makes possible the large investments required for the technically and, in the long-term, also economically advantageous electrification. Because railroad infrastructure is owned in the U. S. railroads are unwilling to make the necessary investments for electrification. The first known electric locomotive was built in 1837 by chemist Robert Davidson of Aberdeen and it was powered by galvanic cells. Davidson later built a locomotive named Galvani, exhibited at the Royal Scottish Society of Arts Exhibition in 1841. The seven-ton vehicle had two direct-drive reluctance motors, with fixed electromagnets acting on iron bars attached to a cylinder on each axle. It hauled a load of six tons at four miles per hour for a distance of one and it was tested on the Edinburgh and Glasgow Railway in September of the following year, but the limited power from batteries prevented its general use

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
5.
Switcher
–
They do this in classification yards. Switchers may also make short runs and even be the only motive power on branch lines and switching. The term can also be used to describe the workers operating these engines or engaged in directing shunting operations, the typical switcher is optimised for its job, being relatively low-powered but with a high starting tractive effort for getting heavy cars rolling quickly. Switchers are geared to produce high torque but are restricted to low top speeds and have small diameter driving wheels, switchers are rail analogs to tugboats. US switchers tend to be larger, with bogies to allow them to be used on tight radiuses, European shunters tend to be smaller and more often have fixed axles. They also often maintained coupling rods for longer than other types, although bogie types have long been used where very heavy loads are involved. Switching is hard work, and heavily used switch engines wear out quickly from the abuse of constant hard contacts with cars, nevertheless, some types have been remarkably long-lived. Diesel switchers tend to have a cab and often lower and/or narrower hoods containing the diesel engines. Slugs are often used because they allow even greater effort to be applied. Nearly all slugs used for switching are of the low hood, good visibility in both directions is critical, because a switcher may be running in either direction, turning the locomotive is time-consuming. Some earlier diesel switchers used cow-calf configurations of two powered units in order to provide greater power, the vast majority of modern switchers are diesels, but countries with near-total electrification, like Switzerland, use electric switchers. Prior to the introduction of locomotives, electric shunting locomotives were used to an extent in Great Britain where heavy trains needed to be started on steep gradients. The steeply-graded Quayside Branch in Newcastle upon Tyne was electrified by the North Eastern Railway in 1905,1, is now part of the National Collection and resides at Locomotion in Shildon. A number of the early German locomotives built for use on lines have been preserved. These specialised locomotives were tall steeple-cab types not seen anywhere else, one example built by Greenwood and Batley in Armley, Leeds is preserved at the Middleton Railway, not far from where it was built. Small industrial shunters are sometimes of the battery-electric type, an early battery-electric shunting locomotive is shown here. The Tyne and Wear Metro has three battery electric shunters built by Hunslet, which are used to haul engineering trains when the supply is switched off. Flywheel energy storage was used experimentally by Sentinel

0-4-0
–
Under the Whyte notation for the classification of steam locomotives, 0-4-0 represents one of the simplest possible types, that with two axles and four coupled wheels, all of which are driven. The wheels on the earliest four-coupled locomotives were connected by a gear wheel. The notation 0-4-0T indicates a locomotive of this wheel arrangement on which its water and fuel is carried on board the engine itself. In Britain, the Whyte notation of wheel arrangement was often used for the classification of electric and diesel-electric locomotives with side-rod-coupled driving wheels. The UICs Bo classification for electric and diesel-electric locomotives indicates that the axles are independently motored, the term Four-coupled is often used for 0-4-0 locomotives. Four-wheeled is also used, but this term can also encompass other wheel arrangements. 0-4-0 locomotives were built as tank locomotives as well as tender locomotives, the former was more common in Europe and the latter in the United States, except in the tightest of situations such as that of a shop switcher, where overall length was a concern. The earliest 0-4-0 locomotives were tender engines and appeared as early as c, 0-4-0 tank engines were introduced in the early 1850s. The type was found to be so useful in locations that they continued to be built for more than a century. Richard Trevithicks Coalbrookedale, Pen-y-Darren and Newcastle locomotives were of the 0-4-0 type, the first 0-4-0 to use coupling rods was Locomotion No. 1, built by Robert Stephenson and Company for the Stockton and Darlington Railway in 1825, Stephenson also built the Lancashire Witch in 1828, and Timothy Hackworth built Sans Pareil which ran at the Rainhill Trials in 1829. The latter two later worked on the Bolton and Leigh Railway. A four-wheeled configuration, where all the wheels are driving wheels, the type was therefore mainly used for switchers and shunters. Because of the lack of stability, tender engines of type were only built for a few decades in the United Kingdom. They were built for a period in the United States. The possible tractive effort of an 0-4-0 within normal axle load limits was not enough to large loads. By 1900, they had largely been superseded for most purposes by locomotives with more complex wheel arrangements. They nevertheless continued to be used in situations where tighter radius curves existed or the length was an advantage
7.
0-6-0
–
This was the most common wheel arrangement used on both tender and tank locomotives in versions with both inside and outside cylinders. In the United Kingdom, the Whyte notation of wheel arrangement was often used for the classification of electric and diesel-electric locomotives with side-rod coupled driving wheels. The 0-6-0 configuration was the most widely used wheel arrangement for both tender and tank steam locomotives, the type was also widely used for diesel switchers. On the other hand, the lack of unpowered leading wheels have the result that 0-6-0 locomotives are less stable at speed and they are therefore mostly used on trains where high speed is unnecessary. The tank engine versions were used as switching locomotives since the smaller 0-4-0 types were not large enough to be versatile in this job. The earliest 0-6-0 locomotives had outside cylinders, as these were simpler to construct, however, once designers began to overcome the problem of the breakage of the crank axles, inside cylinder versions were found to be more stable. Thereafter this pattern was adopted, particularly in the United Kingdom. Tank engine versions of the type began to be built in quantity in the mid-1850s and had become common by the mid-1860s. 0-6-0 locomotives were amongst the first types to be used, the earliest recorded example was the Royal George, built by Timothy Hackworth for the Stockton and Darlington Railway in 1827. Derwent, a locomotive built in 1845 by William and Alfred Kitching for the Stockton and Darlington Railway, is preserved at Darlington Railway Centre. On most branch lines, though, larger and more powerful tank engines tended to be favoured, in New South Wales, the Z19 class was a tender type with this wheel arrangement, as was the Victorian Railways Y class. The Dorrigo Railway Museum collection includes seven Locomotives of the 0-6-0 wheel arrangement, tank locomotives used by Finland were the VR Class Vr1 and VR Class Vr4. The VR Class Vr1s were numbered 530 to 544,656 to 670 and 787 to 799 and they had outside cylinders and were operational from 1913 to 1975. Built by Tampella, Finland and Hanomag, they were nicknamed Chicken, number 669 is preserved at the Finnish Railway Museum. The Vr4s were a class of four locomotives, numbered 1400 to 1423, originally built as 0-6-0s by Vulcan Iron Works, United States, but modified to 0-6-2s in 1951-1955. Finland’s tender locomotives were the classes C1, C2, C3, C4, C5, the Finnish Steam Locomotive Class C1s were a class of ten locomotives numbered 21 to 30. They were operational from 1869 to 1926 and they were built by Neilson and Company and were nicknamed Bristollari. Number 21, preserved at the Finnish Railway Museum, is the second oldest preserved locomotive in Finland, the eighteen Class C2s were numbered 31 to 43 and 48 to 52

0-8-0
–
Locomotives of this type are also referred to as eight coupled. Examples of the 0-8-0 wheel arrangement were constructed both as tender and tank locomotives, the earliest locomotives were built for mainline haulage, particularly for freight, but the configuration was later also often used for large switcher types. The wheel arrangement provided a layout with all engine weight as adhesive weight. The layout was too large for smaller and lighter railways. Two 0-8-0 locomotives were delivered from Andre Koechlin & Cie in Mulhouse to the Austrian Southern Railway in 1862 and they were later sent to Italy and worked over the Apennines between Bologna and Pistoja. In 1952, the Chrzanów works in Poland supplied 81 750mm gauge locomotives, by 1958, China was building their own copies resulting in such classes as the C2, YJ, ZM-4, ZG and ZM16-4. Peckett and Sons of Bristol built a 0-8-0 tender locomotive for the Christmas Island Phosphate Company in 1931, freight engines with an 0-8-0 wheel arrangement were once very popular in Germany. The Prussian state railways had several types of 0-8-0s that were all classified as G7, G8, the latest of these, the Prussian G8.1, was the most numerous German state railway locomotive with over five thousand examples being built between 1913 and 1921. They remained in service with the Deutsche Bundesbahn until 1972, the narrow gauge Heeresfeldbahn class HF160 D were developed for wartime service during the Second World War. The engines were classified as Kriegsdampflokomotive 11. After the war, the locomotives were put to use for civilian purposes, in Russia, the 0-8-0 type locomotives were represented by the various O-class freight locomotives. They were built from the end of the 19th century until the 1920s and they were commonly called the Ovechka and were the most common freight locomotives in Tsarist Russia. Some are still preserved in working order,1,000 of the 750mm gauge standard design, also known as class 159, were built between 1930 and 1941. They were poor performers, so the Kolomna works built a version of these locomotives. Only nine were built before the USSR was invaded in June 1941, on the South African Railways, shunting was traditionally performed by downgraded mainline locomotives. Three classes of 0-8-0 shunting steam locomotives were introduced between 1929 and 1952, in 1929, fourteen Class S locomotives were placed in service. They were built by Henschel and Son in Germany, designed to SAR specifications, the top sides of the tender’s coal bunker were set inwards and the water tank top was rounded to improve the crew’s rearward vision. The second type, the Class S1, was designed by Dr. M. M, loubser, chief mechanical engineer of the SAR from 1939 to 1949

Boiler
–
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil, the heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. The pressure vessel of a boiler is usually made of steel, stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking. In live steam models, copper or brass is used because it is more easily fabricated in smaller size boilers. For much of the Victorian age of steam, the material used for boilermaking was the highest grade of wrought iron. In the 20th century, design practice instead moved towards the use of steel, which is stronger and cheaper, with welded construction, which is quicker and requires less labour. It should be noted, however, that wrought iron boilers corrode far slower than their steel counterparts. This makes the longevity of older wrought-iron boilers far superior to those of welded steel boilers, cast iron may be used for the heating vessel of domestic water heaters. Although such heaters are usually termed boilers in some countries, their purpose is usually to produce hot water, not steam, the brittleness of cast iron makes it impractical for high-pressure steam boilers. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, electric steam boilers use resistance- or immersion-type heating elements. Nuclear fission is used as a heat source for generating steam, either directly or, in most cases. Heat recovery steam generators use the heat rejected from other such as gas turbine. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam and these could burn wood or most often, coal. Flued boiler with one or two large flues—an early type or forerunner of fire-tube boiler, fire-tube boiler, Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam. This is the type of boiler used in nearly all steam locomotives, the heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point. Fire-tube boilers usually have a low rate of steam production. Fire-tube boilers mostly burn solid fuels, but are adaptable to those of the liquid or gas variety. Water-tube boiler, In this type, tubes filled with water are arranged inside a furnace in a number of possible configurations and this type generally gives high steam production rates, but less storage capacity than the above

Steam engine
–
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle, in the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done, the reduced-pressure steam is then exhausted to the atmosphere, or condensed and pumped back into the boiler. Specialized devices such as hammers and steam pile drivers are dependent on the steam pressure supplied from a separate boiler. The use of boiling water to mechanical motion goes back over 2000 years. The Spanish inventor Jerónimo de Ayanz y Beaumont obtained the first patent for an engine in 1606. In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped, Saverys steam pump used condensing steam to create a vacuum and draw water into a chamber, and then applied pressurized steam to further pump the water. Thomas Newcomens atmospheric engine was the first commercial steam engine using a piston. In 1781 James Watt patented an engine that produced continuous rotary motion. Watts ten-horsepower engines enabled a range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained, by 1883, engines that could provide 10,000 hp had become feasible. The stationary steam engine was a key component of the Industrial Revolution, the aeolipile described by Hero of Alexandria in the 1st century AD is considered to be the first recorded steam engine. Torque was produced by steam jets exiting the turbine, in the Spanish Empire, the great inventor Jerónimo de Ayanz y Beaumont obtained a patent for the first steam engine in history in 1603. Thomas Savery, in 1698, patented the first practical, atmospheric pressure and it had no piston or moving parts, only taps. It was an engine, a kind of thermic syphon, in which steam was admitted to an empty container. The vacuum thus created was used to water from the sump at the bottom of the mine
