@Craftech posted:I thought that was the difference between Code 100 HO and Code 83 On30?
This is Code 83 HO
Code 83 rail is code 83 regardless of what scale it is used on.
Code 100 (.100") rail is essentially taller. ME uses the same rail for code 83 (.083") standard gauge HO and O scale On30 track.
