Southern Pacific Switching Layout

Here's my prefer way of dealing with troublesome locomotives.I clean the wheels,wheel contact strip and commutator with 91% alcohol I then spray the contact strips and commutator with TV channel turner cleaner.I clean track with 91% alcohol on a clean rag(I buy gun cleaning patches) and use a bright boy as needed.

I also agree with Ed.Reset the decoder to the default settings.
