My #Germany diagram has been updated for 2026! It focuses on long-distance train lines that run at least three times a day. Providing a more interpretable alternative to #DB 's official #IC and #ICE diagram with a stronger focus on the system (regularly running connections and their frequency instead of the sole line definition) was my initial motivation for starting creating diagrams a couple of years ago.
