I just bought Toby, Mavis, and Salty. And first off I'd like to say they are great models. But Toby won't run until I'm up to about 35 on the Bachmann controller. So I was wondering is this normal, or do I have a defective Toby? Any help is appreciated.

I think this has been asked before, but how do you remove paint from a plastic body? I want to change the number on an engine I have, but I don't know how to remove the old number.
