I've just booked to travel from Sheffield to London and back again in march, i was expecting to receive some kind of tickets via post or printable versions but theres just a reference number, is that all ill need to travel?
What do I give the driver?
You will require your booking reference to travel, ensure you obtain this reference for each journey you book. If you are an Entitlement cardholder in SCOTLAND and have booked concession seats you will also require to present your Entitlement card to the driver when boarding.
Unless they've changed the system all you get is an e-mail confirmation with the reference number on it - no ticket. Either print the e-mail or just make a note of the number.
