I drove 2 hours each way yesterday from the mountains of North Georgia to Atlanta to check out my transformer and engine. With a little oil from the repair shop and some instruction for me on how to hook transformer to track (yes, I'm really that inexperienced with trains)... I got my husband's very old Lionel train purring around the base of the Christmas tree. Well.... today, I decided to see how fast it would go... and the engine jumped the track on a curve and plopped over on its side. I put the engine back on the track (it does not appear to be broken in any way) and turned the handle on the transformer, but it simply won't work. Since this track-jumping incident, the red indicator light on the transformer won't light up when I turn up the juice... but some power is flowing because turning that handle still lights up the engine's headlight and causes the engine to produce "smoke" (even though it's sitting still on the track). Any ideas on what might be wrong? Do engines that "jump the track" short out something in the process? All five of my grandkids will be here on Friday, and they are expecting the TRAIN!! All suggestions appreciated.
