Hey All,

So I purchased the 10th Anniversary Polar Express diesel train (O-Gauge) and when we initially pulled it out and put togetber, seemed to work fine.  However, there was a few times I'd give it power, and the train would not move, only make the sounds and lights.  Then other's the train would move, but no lights.  Now it's losing power to the sounds and lights on select pieces of the track.

I have checked all track pieces, they are in place and secure.  I checked the connections from the track to the transformer and they are correctly linked to the "A" and "U" locations as directed by the manual.  I'm at a loss, nothing seems to be amiss.  Could they have bad pieces of track? Am I not getting the right ampage from my outlet? Any ideas and guidance very much appreciated.  My kid is bummed naturally and hoping to find a resolution.

Thanks in advance!!
