I am travelling with more than one person on one ticket from German Railways. How do I pass the gates?
For each person travelling, hold the square barcode on the ticket against the lit panel on the right-hand side of the gates. The gates will open. Your fellow traveller can now enter or leave the station. You will be the last person going through the gates.
What if it doesn't work? Go to the information pillar next to the gates and push the blue Info button. The member of staff you speak to will be happy to help you. You can also ask the service personnel at the station. They can assist you and your fellow travellers.
