Hi, Looking for a bit of guidance. I inherited a old lionel 4-6-4 #8210 and has Joshua Lionel Cowen on the tender that has never been run. The drive wheels seem frozen when I tried to turn them (I didn't put a lot of pressure on them though so as not to break anything). I assume the gears need oiled but is there anything else I should do? Also there are two wires in the cab of the loco, what are these for? Are they supposed to be connected to each other? I hope I can get this old steamer running without damaging it but the frozen drives are a bit scary.
