If you often travel back and forth to London on the train but you don't go regularly enough to buy a Season Ticket, the Carnet option could save you time and money.

10%* discount with Carnet

Carnet offers a 10%* discount on 5 or 10 single train journeys. You can use each train ticket once for one journey in the direction of travel printed on the ticket.

*The individual ticket journey price is based the relevant 'Anytime Day Return' or 'Off-Peak Day Return' fare TO London being discounted by 10% for journeys to/from London.  For non-London journeys to/from Cambridge, the relevant ‘Anytime Day Return’ fare is discounted by 10%.
