I think I have the same problem. The catenaries on single two-way rail are fixed. You can't delete them with catenary replacer, you can't get an other German, Dutch etc. catenary. I deactivated the catenary replacer and the problem was continue to exist. What can I do. I need these single on way tracks for my freightyard.

Unsubscribe, resubscribe. Then try Network Skins and Extra train tracks, I use those for OHLE turning on / off. I use the same posts as you too, so maybe manual placement if all goes wrong? Hope this helps

I will look into this issue.

Edit: I can confirm that this mod is using the wrong catenary props for the Single Track Two-Way, and that's why Catenary Replacer fails to remove/replace them.
