[5] [7]: 18 Early American locomotives had bar frames, made from steel bar; in the 20th century they usually had cast steel frames or, in the final decades of steam locomotive design, a cast steel locomotive bed – a one-piece steel casting for the entire locomotive frame, cylinders, valve chests, steam pipes, and smokebox saddle, all as a ...
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 way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with.
Firebox of a GWR 6959 Class steam locomotive, showing the underside of the brick arch, constructed from specially-shaped firebricks. Empty firebox of a Baureihe 52, showing the brick arch There is a large brick arch (made from fire brick ) attached to the front wall (boiler throat plate) of the firebox immediately beneath the firetubes.

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.
Components of a locomotive, e.g. 'cylinder' or 'piston rod', use 'Locomotive parts' Individual locomotive classes use the relevant country, railway company or wheel arrangement category. Generic types of steam locomotive e.g. 'Mallet' or 'Crampton', use 'Steam locomotive types'
These were the largest and fastest steam passenger locomotives to run in Japan. [25] Between 1953 and 1961, 47 Class C60 locomotives were rebuilt from surplus Class C59 4-6-2 Pacific locomotives at the Hamamatsu and Kōriyama factories.
