How Does a Train Work?

Answer

A train works by taking up an electrical charge from the metal track through metal engine's wheels on the track. Electric power is transferred from the wheels on to the electric motor and causes it to run. The train motor connects to the locomotive's wheels through a mechanized drive arrangement. As electric current turns the locomotive's motor, the train's motor moves the gears which then spin the engine's wheels and thrust the locomotive down the train rails. The contact point where the locomotive wheel touches the rail is tiny this prevents dust or debris to obstruct the wheel-to-rail contact. Train engine's wheels are kept clean and free of accumulated grime to prevent dirt from obstructing contact with the metal rail which may cause the engine to stall.
