Hi, Hope the community can help. I am a first time interrailer and travelling with my two children over Xmas week from Paris going east and returning to Paris ( 20th to 27th ) , I am looking to get out of Paris around 5pm on the 20th but it seems the new timetable isnt released until mid December ?
What i need to know is
What is the latest bookable Interrail-compatible train from Paris Est on Sunday 20 December 2026 to Karlsruhe, Stuttgart, Mannheim or another suitable point towards Lake Constance?
And specifically:
Is there a direct TGV/ICE from Paris Est after approximately 19:00?
What time does it arrive?
Does it require a reservation?
Can three passengers travel on the Interrail pass on that service?
