Train doors from the inside and outside with beeps and train conductors' signals for closing the train doors. Zugtüren von innen und außen mit Warntönen und Signalen der Zugbegleitung zum Schließen der Türen.
"Train doors in Europe" -> shows only German, Austrian and Swiss train doors. And a bus door. "Train and bus doors in Central Europe" would be more correct 😉. Otherwise nice video 🙂 !
