As I understand from numerous community posts, the inbound/outbound journeys can basically be any train journey in your home country while the pass is valid (only one inbound and one outbound though). Is that true or does the journey have to begin or end at the border or an airport/port?
The reason I’m asking is because the Conditions of Use for Eurail and Interrail Passes states that the journey “can be used” to/from the border or an airport or port. That could be understood either as that is one way to use them or as they “must” be used that way.
If I travel from abroad to and airport or port without train station, would it be OK to travel by train from the same city (travelling from the airport/port to the train station in some other way)?
