I already converted a few MTH auto carriers to 2 rail. Lately I have had a few trains come apart as my layout has some hills and valleys. So I look at each car every time there is an incident. I noticed one of the MTH auto cars I converted has low hung couplers. I pulled it off the track to fix and I also noticed one of the trucks is at the last thread of it's mounting screw. I should have put something on the threads to keep them snug, yet loose enough to allow them to handle my track work.
Anyways with my memory lapse, I can't get the roof off? It seems like the roof is stuck in the middle of the car. I removed the four screws that go up from the bottom. I figure that the car may need some type of squeezing to release the roof in the middle? Before I break something, I did a search here with no luck.
What holds the roof on in the middle??? ( I don't see extra screws)
