We bought this Polar Express O-Guage train set at the Bass Pro Shop a couple years ago. Each year we bring it out to put around the Christmas tree. It is a pain to get it working every year, but this year we’ve been trying for 2 hours and no luck. When we plug the transformer into the wall the red light on the track lights up, the light on the front of the train lights up, but it will not move and the audio sounds don’t work when you press the buttons on the remote. The remote is fine. Any ideas what is wrong? Do we have to lube any contacts as they have never been? Any suggestions would be appreciated. Thanks

Update: Called Lionel and they said take it to an authorized dealer, so my wife drove about an hour to the closest one. Turns out they only sell and don’t fix, but can ship back to Lionel, like we couldn’t do that ourselves. The only good thing was he had a test track my wife could use to trouble shoot. My wife brought the engine and remote. The train didn’t work so the guy at the shop said let me try and pair the universal remote and it worked. Turns out to be the remote. The guy at the shop took it apart but couldn’t see anything wrong. Of course he didn’t have any remotes to sell so my wife ordered one on Amazon for under $50. We got the universal remote yesterday and the train works at home now. I decided now that we had a remote working it couldn’t hurt to mess with the old one. I flexed the circuit board trying to remove it, but it wouldn’t come out because of the knob/speed dial solder to it so I put it back together and it worked. Not sure if it was the flexing of the board but it now works.My wife did find a small piece of solder in the remote when they opened at the Lionel authorized dealer that looks like it might have broken off as it had an indent that looked like a wire connector could have been attached to, but I wasn’t sure. There was maybe one transistor that looked like it might be missing the solder, but who knows. I hope this helps someone else with the same or similar issues that we had.
