My unofficial 🇫🇷 #TGV diagram has got an update for 2026. Once again, not much has changed.
This is my personal attempt to unravel the #French high-speed rail system, if only a little. The highly radial network means that the diagram varies greatly in density. Around Paris, TGV Intersecteur trains have to be grouped together, but there is space for symbols representing important landmarks.

I made every effort to analyse the timetables carefully. However, if you notice any errors in the diagram, please let me know. Please note that I had to make some simplifications, such as primarily showing daily trains.
