steam locomotive

Who was the inventor?

A British engineer Richard Trevithick built a steam locomotive in 1804

How does the invention work?

The heat turns water in the engine's boiler into steam. In many locomotives, the steam is then superheated (heated beyond boiling temperature) before being fed into two or more cylinders. In each cylinder, the steam pushes against a disc called a piston. Special valves control the flow of steam, causing it to press against one side of the piston and then the other. This alternating pressure creates a reciprocating (back-and-forth) motion. See Steam engine (Reciprocating steam engines).
