Unfortunately, even the great Ed's work has succumbed to what looks like unstable resin castings.
Below are an INT CF caboose that has warped sides and a roof that gained a giant bubble in it.
The SOU 40' boxcar with auto end-doors has a slightly warped side and a door that warped so bad it broke the hinges.
The boxcar may be salvageable, but I think the caboose is a lost cause. It's really a shame to possibly lose a piece he created.
