Can I reserve a seat when booking trains within Great Britain?
Tickets for long-distance trains run by some train operating companies automatically include a free seat reservation, subject to availability. This is not shown during the booking process. The reservation is automatically displayed on the ticket.
If you need a seat reservation for other trains, please contact a National Rail ticket office in Great Britain. You can also contact the relevant train operating company online. Unfortunately, it is currently not possible to make a reservation through DB unless it is automatically included when the ticket is booked.
