@jon Fantastic work, Jon! 😲
The border crossings of Geneva's huge former cross-border tram network are missing. And the Riehen-Lörrach tram in Basel.
Apart from that, 🇨🇭 looks complete to me. ☺️
@dominicstucki Do you have a map of the old Geneva network?
@jon
There is a good overview map in the «Eisenbahnatlas Schweiz». To find the exact locations, I recommend the old maps on the official Swiss geoportal.

The second pic shows the two line symbols used for narrow gauge railways.

@dominicstucki Thanks! I’ll have a go. Today is going to be about Swiss and Belgian tramways ;-)
@dominicstucki Ah now understood the Riehen thing - see https://www.g-st.ch/trambasel/bvb_blt/htmlsite/hst_riehengrenze.html So that one has been added!
