I ran 1986 last night for an hour; most switching in Eldon and Olean just to see if they were any running issues. The axels go through a bronze sleeve and the sleeves all sit loosely in a metal side frames. On one trip, a few nights ago, the locomotive ran great, tonight it would go 4″ to 5″ and stop and restart. Took it over to the work bench and pulled off the covers to the gears and made sure the stamping and bronze parts were all aligned. It’s a pretty sloppy design to begin with. Put it back together and it ran fine. If I continue to get interminent pickup problems I’m going to add .010 bronze wires to the tops of the metal frames so the wires ride directly on top the wheels for additional pickup.
