This is legally possible – the legal guardians can decide when their children are mature enough to travel alone. Children need a travel authorisation and their ID to travel with us. Train4you Vertriebs GmbH cannot offer special childcare. Please note: Our trains may have longer intermediate stops at stations at night – the doors are open during these stops. Train4you Vertriebs GmbH accepts no liability if the children get off without authorisation. Further information on the required documents can be found here.
