Interesting.
I'd assert that the clearance needed on the inside is a function of the
width of rolling stock and the maximum distance kingpin to kingpin (the
longer a car, the more the center overhangs the inside of the curve).
I'd assert that the clearance needed on the outside is a function of the
widthe of rolling stock and the maximun distance kingpin to end (the longer
the distance from the trucks to the couplers, the more the corners overhang
the outside)
So I am not sure that a formula like 2 studs beyond ties, etc. works in all
cases. You need to specify your maximum vehicle envelope, and use it to set
clearances. Then enforce it by disallowing vehicles that exceed it from
operating.
I think GMLTC made a "test car" to check clearances when designing new
modules...
Note that 8 wide needs clearances that are *more* than just one stud wider
than 6 wide, in general, because the cars are longer on average and may have
more end overhang as well.
