My son got a Santa Fe RS-3 Scout Freight Lionchief for Christmas. He played with it on Christmas day with me watching him. When done we put it up. Last night we set it up so he could run it at night. Track all snapped together. When we plugged the power supply the LED on the track did not light up. Train was on the track with no power. We read through the manual. We unplugged the power supply, replugged it in. Removed the train. Put the train back on. Made sure all track sections were snapped tight. Still no power? It was running fine when we put it away on Christmas day but now there's nothing? Any ideas? There is no damage to any of the track pieces. I can only think that somehow the power pack was damaged? Thanks Greg
