I have a North Pole Express Big Hauler that I have had for a few years. I set it up this year and it ran fine for a few days. When I tried to run a few days ago, the power light on the power supply/speed controller goes dim as soon as I put the engine on the track. What would cause that? How can I fix? Thanks in advance for any help you can give. I miss running the train!!! ![Undecided :-\](https://www.bachmanntrains.com/home-usa/board/Smileys/default/undecided.gif)
