@Pantenary posted:However, at any kind of speed, (say MTH 30smph or higher), derailments out of the curves are frequent.
Derailments coming out of a curve sound a trifle odd, generally when long cars don't like a particular curve radius around their limits they dend to derail going into it. Maybe the couplers are hanging up on something preventing them from swinging back to center?
