Thanks so much for the info!!! While I was waiting for a reply I kept researching and found that maybe some light grit sand paper to clean the top rail would help so I did this also I found that the power supply was not connecting with the track well so I bent the connectors better and Voila we have a very well working train and my daughter is a very happy first time train owner . There is a section of track that is bent so the cars keep derailing so we will have to get new track.
