DetailsSU 253-15 Locomotive _Designed by Rusty Smith ( https://grabcad.com/library/su-253-15-locomotive-1 ) _A steam locomotive is a railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material, usually coal, wood or oil, to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels. Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind.Steam locomotives were first developed in Great Britain during the early 19th century and dominated railway transport until the middle of the 20th century. From the early 1900s they were gradually superseded by electric and diesel locomotives. _The basic features that made George and Robert Stephenson’s Rocket of 1829 successful—its multitube boiler and its system of exhausting the steam and creating a draft in its firebox—continued to be used in the steam locomotive to the end of its career. The number of coupled drive wheels soon increased. The Rocket had only a single pair of driving wheels, but four coupled wheels soon became common, and eventually some locomotives were built with as many as 14 coupled drivers. Steam-locomotive driving wheels were of various sizes, usually larger for the faster passenger engines. The average was about a 1,829–2,032-mm (72–80-inch) diameter for passenger engines and 1,372–1,676 mm (54–66 inches) for freight or mixed-traffic types.
