As far as I understood, the ticket there specifies a specific departure time, what about the return ticket? Do you need to register it somewhere later or can you return at any time? Please advise if you know.
You can return on any train type for which you have a ticket. If you bought for express, then board any express train. If for a regular electric train, then on a regular one.
Thank you for the information! Can you please tell me about the seat? I see that the return ticket indicates the seat and apparently the train car. Does it mean that the seat is reserved for me on any return train, or should I just sit in any available seat?
@mr: For any available seating. The seat is reserved only on the train for which you have a ticket.
