American steam locomotive

American steam locomotives are powerful engines that use steam generated by boiling water to move trains. They traditionally consist of a boiler, where water is heated by burning fuel like coal or oil, producing steam under pressure. The steam then drives pistons connected to wheels, propelling the train forward. These locomotives played a crucial role in the development of the U.S. transportation network, especially during the 19th and early 20th centuries. Known for their strength and durability, they enabled large-scale freight and passenger transport across vast distances before diesel engines became dominant.
