Also gone through every German-speaking country's S-bahn and bought in the 2024 timetable (where German wikipedia has updated). Only a few systems had changes - Hamburg reorganised its numbering system, Nuremburg swapped 3 branches around, Berlin flipped two branches around, Vaud decided to use R instead of S (being Francophonic).
