Howdy from a total newbie (I bet there are alot of us newbies today!). I got a new-old stock K-line o-gage army train set for my son. I set up the supersnap track and transformer. I tested the train for a few laps----worked great. Then my son wrecked it while I was in another room and it is now showing short on the power pack. I took apart the track and see no shorts or foriegn objects. Rotating the speed control knob to zero (per instructions) does not reset the transformer. I also notice that the green light on the piece of track where the wires connect shines green when no train is on the track but goes out when I mount the locomotive. Could he have shorted out the transformer or the locomotive? Any help appreciated.
