Has anyone experienced what appears to be zinc pest issues with RMT rolling stock? I have a significant number of items going back a number of years. So far I have had two couplers disintegrate on me - one was a Bethlehem Steel depressed flat car and another was a Jersey Central covered hopper.
I have tried to contact RMT twice to see if replacement trucks were available but the emails were not answered. On the covered hopper, I am not even sure how to get the truck off - could possibly replace the knuckle - I have a press and tools - not sure if the knuckle is a post war type I could get from a parts supplier.
