A steam railway is a type of railway that uses steam locomotives to pull trains. These locomotives burn coal, wood, or oil to heat water in a boiler, creating steam that drives the engine. Steam railways were the primary mode of transportation in the 19th and early 20th centuries, playing a crucial role in the industrial revolution and the expansion of cities. Today, many steam railways operate as heritage or tourist attractions, allowing visitors to experience the charm of vintage trains. They often feature restored locomotives and carriages, providing a glimpse into the past of rail travel, such as the famous Union Pacific Railroad and The Flying Scotsman.
