the problem is not the 18" curve per se, but the crossover that has two of them in an s curve without any straight track in between. my grandfather used to run a mallet 2-8-8-2 and a 2-10-2 through 18" curves. but there were no s curves without at least 9" of straight track between the curves.
they looked horrible but ran pretty well. i ran u30c's and sd45's around 18" curves successfully as long as the first car wasn't shorter than 50'.....
once again, no s curves without an intermediate straight....
