A steam locomotive is a locomotive whose primary power source is a steam engine. The most common form of steam locomotive also contains a boiler to generate the steam used by the engine. The water in the boiler is heated by burning combustible material – usually coal, wood, or oil – to produce steam.
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. [1]: 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times.
The maintenance of the new diesel locomotives in filthy steam sheds soon proved difficult and, although some old sheds survived, many new diesel depots were built on new sites or on the sites of the old steam sheds. The major problem was the disposal of oil, which initially was left lying around causing pollution and safety issues.
Motive power may refer to: In thermodynamics, natural agents such as water or steam, wind or electricity, that do work; In mechanics, the mechanical energy associated with the motion and position of an object; In physics, a synonym for power; In mechanical engineering, the source of mechanical power of a propulsion system; It may also refer to:
Locomotives are classified by track gauge, motive power, function, power rating and model in a four- or five-letter code. [21] The locomotives may be Longer Hood Front (LHF), where the driver cabin is behind the hood of the engine or Short Hood Front (SHF), where the cabin is located towards the front.
The quantity Q m of motive steam per unit suction quantity is a function of both the motive ratio of motive steam pressure vs. suction pressure and the compression ratio of delivery pressure vs. suction pressure. In principle, the higher the compression ratio and the lower the motive ratio the higher will be the specific motive steam ...
Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
