You can add a London Travelcard to the ticket you’re loading onto your Smartcard for any journeys starting from or going to a c2c station outside the London TfL zones. You’ll be able to tap in or out at the London station of your choice on the Oyster reader with your Smartcard. This includes the extended PAYG validity area (Grays, Chafford Hundred and Ockendon).
You won’t be able to purchase London Travelcards from any other stations inside the London TfL zones on your Smartcard. Please see our route map for the TfL travel zones and Oyster validity areas.
