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 locomotive that has a tender cannot function without it, but (with rare exceptions) the tender does not contribute to traction. To establish the "largest" category, several factors take precedence: overall weight, which gives traction over driving axles; size (length and height of engine itself); and power, which may be in terms of raw ...
Cyldon 13/2 steam engine with semi-rotative valve gear. The 13/2 is interesting for a couple of reasons. Firstly, the overall layout, with the crankshaft, cylinder, boiler and burner all in line longitudinally, on a long thin wooden base. Secondly, and the most interesting aspect, is the semi-rotative valve gear (see below).
A steam motor is a form of steam engine used for light locomotives and light self-propelled motor cars used on railways. [1] 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.
Steam engines and turbines operate on the Rankine cycle which has a maximum Carnot efficiency of 63% for practical engines, with steam turbine power plants able to achieve efficiency in the mid 40% range. The efficiency of steam engines is primarily related to the steam temperature and pressure and the number of stages or expansions. [15]
The Baker mechanism consisted of the following parts: A frame which replaced the mounting for the expansion link. It came in two basic forms, depending upon whether it was attached to the locomotive frame at both ends or only at the front. In either case it had two pivots: one forward and at the top of the frame, and one below and to the rear.

When the engine is running under load the valve heads are forced by steam pressure onto the support plates and work like standard pistons (Regelkolbenschieber). If steam admission ceases or, on a steam locomotive, the regulator is closed, the pressure drops, the valve heads remain in the inside dead centre position near the centre of the ...
