I am working on a Lionel PW ALCO AA Santa fe #204 set. After servicing the engine I am onto the chief complaint, poor pulling power. The engine motor runs great, but the wheels spin. I noticed that the battery and solenoid are all on teh front unpowered truck, all the weight seems to be up front. Can this be causing the issue. If I add weight to the area by the motor truck will that help. I do not want to use bull frog snot, any suggestions will be appreciated
