Travel in a group to save 1/3

If you are planning a trip with a group of three to nine people, there's good news for you! You can take advantage of group travel discounts that are offered by many train companies.

Split Tickets to save an average extra 30%

This method is legal and can often result in cheaper fares. For example, if you are travelling from A to B, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than purchasing a direct ticket.

Get 1/3 off with a Railcard

Railcards offer discounts of up to 1/3 on most tickets. There are various types of Railcards available to cater to different groups of travelers, such as the 16–25 Railcard, the Family & Friends Railcard, and the Senior Railcard.
