Hello all, I have been away from the trains for a while but now as the sumer season comes to a close i will be back at it. I was just doing some track cleaning and loco steaming. I recently bought a new Mantua 0-6-0 Tank switcher CPR for use on my transfer table, no matter how clean my rails or wheels are i can not get it to work satisfactory. wall1 I know its no 2-8-0 Spectrum but i have to touch it 20x in 10ft of track! driving me crazy, I have cleaned the brass wiper contacts on the right hand side but I see no electrical connection on the other side, How do these work?? and is there a way to improve the operation of short wheel base engines??
