I think this is the limit, at least on my layout. I am amazed that I have been able to get 60 old style tin cars to stay on the track but what a hoot. Pulling power for the Big Boy does not seem to be an issue. It is just getting all of the cars around the 54″ curves. At all times it is pulling through three curves with one being a 180 degree loop back.
