This is a great set but my only problem with it is the box car with the spinning tree isn't working properly. It adds so much friction to the train that the train is hardly able to move. The train works great if I take the spinning tree box car out of the train. I've checked the worm gear and other gears and don't see how I can make it work any smoother. I am wondering if other people are experiencing this issue.
