A locomotive is a self-propelled vehicle used for pulling trains along railway tracks. It's the powerhouse that provides the force to move a string of cars. Locomotives come in various types, including diesel, electric, and steam. They're essential for transporting goods and passengers across long distances. Unlike a single train car, the locomotive is designed specifically for generating power and traction. Think of it as the engine that drives the entire railway system. It is quite different than a subway.
