I recently bought a trainset from a vender at a train show. The set is a Bachman Yard Boss set. When I got the set home, I set it up on the table and tried to run. The engine would not budge. It sat there and made a funny clicking like noise. The track was connected, so I knew that it could not be a short in the tack somewhere. I was curious to find out if I needed to send the engine in or the whole trainset in order to get it repaired. It came with a lifetime warantey and the origional paperwork, it just has never been filled out. If someone could please guide me through this, that would be great. Thanks.
