@pettter @jon Not focused on the failures, nor especially in trains in Europe, but the closer I know is probably RMTransit for all stuff rails (mainly at cities-level, so subway and rails, but not only, as this one about DB high-speed trains: https://www.youtube.com/watch?v=Y86JBL37m4M)
Otherwise, at further distance:
- Tim Traveler, for mixed transport and trip stuff (mainly in Europe): https://www.youtube.com/@TheTimTraveller
- City Beautiful, for all city planning/urbanism things, and thus transport: https://www.youtube.com/@CityBeautiful/
