Up to two children under the age of 5 may travel for free when accompanied, so you will not have to purchase a ticket for their journey. Please keep in mind that they will not have a seat reservation and they will be expected to sit on your knee if the train is busy. If you would like a seat reservation for them you will need to purchase a child's ticket.
For children aged 5 to 15 inclusive there are discounted fares available. These fares will be displayed during the booking process.
One of the most economical ways to purchase a child's fare can be to purchase a Family & Friends Railcard. This gives a 33% discount on adult fares and a 60% discount on child fares when all travelling together. For further information please see www.familyandfriends-railcard.co.uk.
