It is usually not essential to reserve seats on all trains (except sleeper trains). However, we STRONGLY advise that you pre book seats if you are travelling over busy times like Easter or Christmas, on longer journeys (you don’t want to be standing for 4 hours!), and if you absolutely have to get a specific train and need a guaranteed seat.
If it is possible to pre book a seat, we can book this for you at a small fee – you will then get a confirmation of the booking which you will need to carry with your pass.
