MTH Tank car 2 rail conversion adapter
I made this adapter to convert some O-scale MTH Railking modern tank cars from 3-rail to 2-rail trucks. These MTH cars have the screws coming down from inside the frame into the trucks. This adapter allows the use of conventional trucks that are screwed in from below like Weaver or in my case Atlas 70 roller bearing trucks. No glue needed so you can convert back if needed.
