Ed et al --
The short answer is "maybe." 72-foot cars with body-mounted couplers will do
OK
on 30" curves as long as the nearest parallel track is at least 3-3/4 inches
away, centerline to centerline. The problem comes where the curve meets the
straight. You will need transition curves (spiral easements) offset by about
3/4 inches, easily achieved by using a three-foot .172 rail as a spline against
which to draw the easement centerline. No calculations required.
