The steam then either travels directly along and down a steam pipe to the engine unit or may first pass into the wet header of a superheater, the role of the latter being to improve thermal efficiency and eliminate water droplets suspended in the "saturated steam", the state in which it leaves the boiler. On leaving the superheater, the 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.
This will give evenly spaced exhausts when the engine is working compound. Two arrangements are also possible on a four-cylinder engine: all four cranks set at 90 degrees. With this arrangement the cylinders act in pairs, so there are four impulses per revolution, as with a two-cylinder engine. Most four-cylinder engines are of this type.
Most powerful steam locomotive ever static tested.

The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte , [ 2 ] and came into use in the early twentieth century following a December 1900 editorial in American Engineer and Railroad Journal .
The Milwaukee County Zoo's two steam engine locomotives, which power the zoo train along with two diesel engines, will be retired in 2024. The remaining steam engine is scheduled to run July 19-20 ...
A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. Most locomotives operate with a steam pressure of 200 to 300 psi (1.38 to 2.07 MPa). [1] In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).
