A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels.
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
The locomotive Saxonia was operated by the Leipzig–Dresden Railway Company and was the first practical working steam locomotive built in Germany. Its name means Saxony in Latin.
Under the Whyte notation for the classification of steam locomotives, 4-2-2 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and two trailing wheels on one axle.
Under the Whyte notation for the classification of steam locomotives, 2-2-2 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle. The wheel arrangement both provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types. This configuration was introduced in 1834 on Robert Stephenson's 'Patentee locomotive' but it was later popularly named Jenny Lind, after the Jenny Lind locomotive which in turn was named after the popular singer. They were also sometimes described as Singles, although this name could be used to describe any kind of locomotive with a single pair of driving wheels.
The Union Pacific Railroad 9000 Class was a class of 88 steam locomotives, built by ALCO for the Union Pacific between 1926 and 1930.
Novelty was an early steam locomotive built by John Ericsson and John Braithwaite to take part in the Rainhill Trials in 1829.
The Deutsche Reichsbahn-Gesellschaft's BR 01 steam locomotives were the first standardised (Einheitsdampflokomotive) steam express passenger locomotives built by the unified German railway system. They were of 4-6-2 "Pacific" wheel arrangement in the Whyte notation, or 2′C1′ h2 in the UIC classification. The idea of standardisation was that it would reduce maintenance costs; i.e. if a BR 01 whose engine shop was in, say, Berlin broke down in Dresden, instead of having to ship the necessary part from Berlin and take the locomotive out of service, a part from the Dresden shop could be used as all of the engines, parts, and workings were exactly the same and produced nationwide. Thus it was a "standard" product for engine shops.
The Prussian state railways' Class P 10 were 2-8-2 "Mikado" type passenger-hauling steam locomotives built for hauling heavy express trains in the hilly terrain of the Mittelgebirge. They were the last Prussian passenger train steam locomotives to be developed in Prussia before the state railways were merged into the Deutsche Reichsbahn, who eventually designated them as DRG Class 39.
Johann Karl Friedrich August Borsig was a German businessman who founded the Borsig-Werke factory.
The Class S 2/5 locomotives operated by the Royal Bavarian State Railways included two express train, steam locomotives of American origin which were fitted with Vauclain compound engines.
The Einheitsdampflokomotiven, sometimes shortened to Einheitslokomotiven or Einheitsloks, were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components.
The Saxon Class XV T was a class of goods train steam locomotive operated by the Royal Saxon State Railways, which had been conceived for hauling trains and acting as banking engines for routes in the Ore Mountains. In 1925 the Deutsche Reichsbahn grouped them into their DRG Class 79.0.
The locomotives WURZEN and OSCHATZ were early German steam engines operated by the Leipzig–Dresden Railway Company (LDE) for mixed duties. They were tender locomotives.
The South African Railways Class 18 2-10-2 of 1927 was a steam locomotive.
A steam motor is a form of steam engine used for light locomotives and light self-propelled motor cars used on railways. The origins of steam motor cars for railways go back to at least the 1850s, if not earlier, as experimental economizations for railways or railroads with marginal budgets. These first examples, at least in North America, appear to have been fitted with light reciprocating engines, and either direct or geared drives, or geared-endless chain drives. Most incorporated a passenger carrying coach attached to the engine and its boiler. Boiler types varied in these earlier examples, with vertical boilers dominant in the first decade and then with very small diameter horizontal boilers. Other examples of steam motor cars incorporated an express-baggage or luggage type car body, with coupling apparatus provided to allow the steam motor car to draw a light passenger coach. An early example with the all-in-one was photographed working on the Nashville, Chattanooga & St. Louis Railroad during the American Civil War, in Tennessee, circa 1863-64. One American firm, Grice & Long, devised various versions in the mid-1860s for use on suburban and city street railways, using their proprietary mechanical patents. In the 1930s some highly evolved steam motors represented one of the final developments of the steam locomotive. The concurrent development of internal combustion-powered or electric-motored railway motor cars proved most popular circa 1900-1950s and those obviating the need for steam-powered cars.
A return connecting rod, return piston rod or double piston rod engine or back-acting engine is a particular layout for a steam engine.
The Central South African Railways Rack 4-6-4RT of 1905 was a South African steam locomotive from the pre-Union era in Transvaal Colony.
The Grand Duchy of Mecklenburg Friedrich-Franz Railway grouped various 2-4-0 steam locomotives built between 1849 and 1856 into its Class II. These included five locomotives that had originally been delivered with a 2-2-2 wheel arrangement.
The MÁV class 601 is a class of Hungarian four cylinder Mallet -type locomotives, which was designed to haul long and very heavy cargo on very steep railway tracks. With their 22.5 meter length and 2200 KW power, they were the largest and most powerful steam locomotives which have ever built before the First World War in Europe.
