@rplst8 posted:Yes, the reading I’ve done on it indicated that much of the trouble was just a lack of straight and trouble free track work to run at the speeds it needed to be efficient.
Don’t forget the Qs too!
The S2 was being used right up to its grade crossing accident in early 1949. With the diesels coming on line, it was not cost effective to fix it.
I have 3rd Rail's Q1, an absolutely awesome looking engine. Unfortunately, it has issues even with my O-90 curves. Maybe the same issue as mentioned with the driver springs, but I have not had problems with my 3rd Rail S2.
