The Workings Of A Model Train Locomotive

December 27, 2006

A model train locomotive runs by picking up an electrical current from the metal rails through metal wheels that ride on the rails. The electricity is transferred from the wheels to the motor, which causes the motor to run. The motor connects to the wheels through a mechanical drive system. When the electricity turns the motor, the motor turns the gears that turn the wheels and push the locomotive along the train tracks. Simple!

The contact point where your model train locomotive wheel meets the rail is extremely small. That’s why; it doesn’t take much in the way of dirt, dust, or debris to obstruct the wheel-to-rail contact. Dirt can build up, so it is important that you keep the wheels clean and free of accumulated dirt. If the wheels of your locomotive become dirty, they may not make good contact with the metal rails, and your train will stall.
Remember, plastic wheels don’t conduct electricity.
