Plus, one of the train motors died, which required Steve to go to the LEGO store
and buy the 4512 Cargo Train as a replacement. I also think the track was dirty
and stopped conducting well, since by the end of the weekend the volunteers were
having to help push the trains along the rails.
Overall, though, I thought the trains did a tremendous job. Without them,
shutting down part of the GBC for repairs would have been impossible.
