How Locomotive Steam Engines Move Themselves Forward

Steam Locomotive Movement Mechanism

A steam locomotive moves by converting the energy stored in coal (or another fuel) into heat, which generates steam. The steam is then directed into cylinders where it pushes against pistons, which are connected to the locomotive's wheels through a system of rods and cranks. The pressure of the steam and the movement of the pistons cause the wheels to turn, propelling the locomotive forward.

Pressure and Piston Movement

The expansion of steam pushes the pistons that connect to the driving wheels that operate the locomotive. This pressure created by the steam is harnessed to move the mechanical parts of the locomotive, allowing it to move forward.
