Hi, I have a Pennsylvania Flyer set I purchased for me son last Christmas. We are novices at Trains and have had huge issues with this sset and particularly the transformer. In the year we have had to have an engine serviced and a transformer replaced because it over heated as soon as it went in reverse. Today we set up the train for Christmas and the new transformer will not supply power to the track. The transformer is a standard CW -80 Transformer which is only operating the track. Is there an alternative to this transformer reasonably priced? Do you have any advice as to why no power would be going to the track. I checked the leads and they seem secure. Thanks for any help you can offer. Bob Mealey and very disappointed son.
