I'm laying my trackwork right now. Although I'm not using Peco or Tillig track I am using Atlas and Micro Engineering.
What I found is that Atlas code 83 track is wider than the Micro Engineering code 83 at the bottom of the rail. Good thing is the Atlas joiners will work but fit loose on the ME track. I am soldering those joints due to the loose connection and all is working out fine.

HO flextrack (and special work like turnouts and crossovers) interchanges between makers. It's all the same gauge, and the railjoiners will join even rail of different sizes. I have a mix of Atlas, Peco, and Micro Engineering, and it all works fine. Not to worry.

Hello
I am working on a new HO project using Peco code 83 track. The problem is available turnouts from Peco, e.g. #4 and wyes. I wonder if anyone has used Peco Code 83 in HO, and have mixed in some Tillig turnouts?
