As promised here are three diamond crossings for OS Railway. They are completely compatible to Train Tracks by Depronized.
Both the 60° and 90° crossing have a track length of 100mm, the 30° crossing has a track length of 200mm.
Maybe in the future I will release a slip switch, but first I need some more tracks and cars to play with :D
UPDATE: Files with suffix v2 have an increased space for wheels
