Today I was running the Marx on my new layout setup. All of a sudden it picked up a burst of speed and flew off the end of the track...... And straight down to the floor. A burst of rather colorful words burst forth from my mouth as a I ran around the table to see what the damage was. (Most of which I hope my daughter will forget before the next time she talks to Grandma. ) Thanks to thick carpet and diecast construction, the loco escaped without any damage and I put her back on the track for another run. Now here comes the odd part..... When I got the loco, the headlight would flicker, flash, and only occasionally work at all. I figured there must be a short somewhere and have been trying to work up the courage to look into it further. After attempting to become airborne, the light started working perfectly. Apparently the fall knocked something back into place because it shines bright as day now with a nice, steady glow. I'm at a loss ot explain it. This is the first time I've ever heard of a fall FIXING an engine. Honestly, I'm sure at some point it will have to be looked at. I'm just scared to tear into it myself for fear of doing permanent damage messing with stuff I have no experience with.
