Steam Locomotives
Steam locomotives are railway locomotives that produce their pulling power through a steam engine. These locomotives use steam as their working fluid to generate power, typically by heating water in a boiler to create steam. The steam then expands through cylinders, pushing pistons that drive the locomotive's wheels. Steam locomotives were widely used in the 19th and early 20th centuries for hauling freight and passengers on railways before being largely replaced by diesel and electric locomotives. They are characterized by their iconic appearance, with a large smokestack, wheels with connecting rods, and a distinctive chugging sound.
