The other is to enable more fuel-efficient operation when the locomotive is running in a steady state: the throttle is set wide open and the power output is controlled by moving the reversing lever closer to its mid-point ("reducing the cut-off") to limit the amount of steam admitted to the cylinders. a train brake lever, which controls the ...

LNER Class A3 4472 Flying Scotsman was the first steam locomotive to officially reach 100 mph (160 km/h), on 30 November 1934. 41 018 climbing the Schiefe Ebene with 01 1066 as pusher locomotive (video 34.4 MB) A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam.
Great Western locomotives with their distinctive copper-rimmed chimneys The new-build steam locomotive Leviathan, a 4-4-0 with a large spark-arresting chimney. The chimney (smokestack or stack in American and Canadian English) is the part of a steam locomotive through which smoke leaves the boiler.
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' Locomotive systems or technologies e.g. 'Boiler feedwater' or ...
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.
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgian railway engineer Egide Walschaerts in 1844. [ 1 ] [ 2 ] The gear is sometimes named without the final "s", [ a ] since it was incorrectly patented under that name.
The smokebox incorporates the main steam pipes from the regulator (or superheater header), one leading to each valve chest, a part of the cylinder casting. These pipes may pass through the smokebox wall to join with the cylinder (outside steam pipes) or may stay within the profile of the smokebox (inside steam pipes).
