Lionel SLS-257-12 Motor - The SLS-257-12 motor is used in the Lionel prewar 257 and 258 steam locomotives, among others. This motor has been thoroughly serviced in our shop. That doesn't mean we put it on a test track. Service means that we rebuild these motors and if included, their E-Units, as necessary, replacing bushings, bearings, brushes, springs and even armatures so that you receive a motor that needs nothing more than installation. We use stock pictures because all of our motors are like new! Tired of buying and fixing someone else's junk? Buy it an install it!
