I'm trying to provide some power to my Susie-Q boxcar to simulate a fire with flickering LEDs in a barrel for some hobos. I bought a Lionel 8077-57 Lionmaster Challenger Single Arm Collector Roller from Trainz (via eBay), a picture of it is at the bottom. I got it installed, and it works okay in a test mode. The problem is that the distance from the top of the collector (the part with the blue dot) to the point of contact with the rail on the roller, the part pointed to by the arrow, is too great. The assembly lifts the wheels off the track a bit too much. Is there a similar collector roller like this one, but smaller, that anyone can point me to? I could grind down the part of the truck that this attaches to, but that would be a lot of work.
