Hi there,
I’m travelling pretty soon, going from London St. Pancras to Paris Nord and then getting a connection from Paris Est to Strasbourg on the same day. I will have about 40 mins to catch the train to Strasbourg, which (in theory) should be sufficient. As a reservation was required however, I am a little concerned about the options I would have, if the Eurostar was running late and I was to miss the connecting train. Will I be able to simply catch the next train or would I need to speak to the staff at the station first and validate my ticket for the next connection? If so, is the validation dependant on anything (e.g. seat availability for interrrail users? Would there be an additional charge for this?
