Some SBB catenary has been available at oliver-trainz.ch, might be still downloadable from the WaybackMachine (SBB Fahrleitung I and following).
It's not publishing, it's my creation. I have one last addition to finish it at Vallorbe station. You can see more photos and description in the Swiss forum (Map La suisse romande).
You have to leave me until January 01, 2022 to finish the MAP:hehe:. After yes I would like to publish it for free but unfortunately I do not know how to make a website. So I don't know how to do it and there are a lot of KUIds. Moreover The map is only on TANE SP4. I am also looking for testers on TANE. If you are motivated we can recruit at the beginning of January
