If you have purchased a flexible ticket (including an Anytime, Off-Peak or Super Off-Peak ticket) you may be able to add or change your seat reservation(s) before you start your journey.

To add or change your reservation, sign in to My account and then select Order status and refund applications. This will give you a list of your bookings, please select Amend journey on the booking you wish to make a change to.

You can then search for a journey to alter your reservation, and the search results will only show you trains on which your ticket is valid. Select the train you would like to reserve a seat on, and continue through to the following screens. Once you click complete, you will receive an e-mail confirming details of your train times and seat reservation. Please make a note of your new seat reservation details or take the e-mail with you when you travel.
