Hi. I'm new to trains (I had some when I was a child, but I never paid any attention to the specifics). My stepson has a Lionel "O" gauge train with some track that my wife asked me to place around the tree. I put a small section of track together on the floor so I could test it. To my surprise, it worked well. That is, it worked until I hit the reverse button. Then it all went haywire. I believe the problem is in the transformer control for forward and reverse (when I play with the reverse button I can get it to work for a bit but the slightest touch will render the unit inoperative once a gain). I would either like to get a new transformer or bypass the reverse switch. The transformer recommends only using a 3 amp power pack. I believe the power pack is a 77 volt unit. Does anyone have any suggestions?
