From Pathfinder Wiki
Steam powered locomotives use burning coal or wood to heat water enclosed in a large boiler. The steam released from this boiler acts much like the steam that emanates from a kettle of boiling water on the stove. By channeling the steam’s pressure into an engine cylinder, it pushes a piston that provides mechanical power to the wheels. Steam locomotives dominated rail transport until the mid-1900’s when diesel and electric locomotives took over. Steam locomotives had to stop periodically to receive a new supply of water plus logs or coal.
