Steam-powered trains are locomotives that use steam engines to generate power. These trains burn coal or wood to heat water in a boiler, creating steam. The steam then moves pistons that drive the wheels, allowing the train to travel along tracks. This technology revolutionized transportation in the 19th century, making it faster and more efficient. The first successful steam-powered train was built by George Stephenson in 1814. Steam trains played a crucial role in the expansion of railroads, connecting cities and facilitating trade. Although they have largely been replaced by diesel and electric trains, steam-powered trains are still celebrated in heritage railways and museums.
