Bruce wants help from more experienced model railroaders and asks:

“Hi, I bought a prewar yankee 616w which I have up and running. The engine runs well but it will not pull the 3 cars. It runs great on its own and will pull a car, but each additional car slows it and three cars will not move. The wheels spin but it does not seem to have the traction. It has a whistle which works but I do not know if it is original. My one thought was that maybe the whistle was too heavy and off loading the engine wheels. I do not know if there was ballast or weights to add traction. Any advise would be appreciated.”
