Hi, Need help... We bought an old S scale American Flyer train set at an estate sale. After cleaning up the track and replacing the VERY bad power cord on the transformer, we got it to work. It goes in reverse. I read that to change directions, I had to turn off the transformer and turn it back on and the train would move in the opposite direction. It just keeps going backward. I turned the engine around on the track and it still goes backward. Any thoughts on that? Seems to have good power. It has the link couplers so it must be 1946-1952 vintage. Any help or advice would be appreciated. Thank you. Update: my wife moved a switch under the tender and it stopped working.... Now its not going anywhere???? Thanks for your help, my grandson is VERY excited...
