I recently purchased the On30 Holiday Trolley and the HO reversing track set for my Dept. 56 Village. It works pretty well, but it will occasionally stop at one end of the track or the other and not start up without a little tap to get it moving again. The light on the trolley is lit when this occurs, so it's getting power and I'd assume has reversed itself. I tried cleaning the track with Bachmann track cleaner, but that didn't really make a difference. Sometimes it will run for a while without issue, then suddenly it will have the issue every 5 minutes or so. When the issue starts, the trolley always stops at the same end of the track. If I turn the trolley around, it will stop at the other end (this is true most of the time, but not 100%). If anyone has any ideas as to what I can check. Is the issue the track or the trolley. I don't have another engine right now to test with to see.
