I've been following the layout forum for a while and some of you guys tend to get picky about reverse curves. Any time you see one, you point it out and offer an alternative layout, which is definitely the coolest part of the whole deal, but...
I have two questions:
1. How come you don't question reverse curves in switching yards?
2. Is there a curve diameter where a reverse curve is acceptable? Reverse curves are TIGHT on 27", 31", and even 36", but what about 42", 48", 54" or 72" curves?
