Steam locomotive - Wikipedia

How a steam locomotive works, in 100 words ; Coal or oil is directed into the firebox (item 27 in the large diagram below), where it burns at high temperature. The firebox is surrounded by water in the boiler, and many tubes (28) extend from the firebox's front along the boiler barrel (29). Very hot gases travel through these tubes and up the smokestack/chimney (33).
