Hello Goateneack34
Usually you can find buttons near the doors and you must press these buttons 2-3 minutes in advance or when the train leaves the previous station. This request will then be displayed in the driver’s cab. Most trains have now displays and/or loudspeaker announcements to inform you about the next stations and remain you that the stop is on request. If no buttons are available, inform the train’s staff. .
At the stations, buttons are also available to inform the driver with a signal. If no buttons are available, stand on the platform to be visible.
Kind Regards
Danhiel
