These traction motors are built around an axle that connects the wheel set, capped off with bearings, which is what can be seen from the outside. Each set of wheels has its own motor. On typical locomotives, there are six traction engines and six sets of tires. Up front, in the cab, the engineer has two choices, forwards or backwards. “[The motors] are just like a drill motor,” Mike on steel tracks],” Mark the main braking system Cook said. “They go for- Davis said. “In your car, of the locomotive ward and backwards, just you have resistance from The traction motors also like an electric drill.” the rubber on your tire and give locomotives the ability The motors also have the the asphalt on the ground. to have a dynamic braking ability to produce energy if Here it’s the thickness of a system, which acts similar- a train is going downhill, dime, so it’s a very low re- ly to a “Jake brake” on a which also helps with sistance.” semi.
