Travelcards on Oyster
3.5 You can use a valid Travelcard season ticket on your Oyster card provided that any pay as you go balance on your Oyster card is not in debit. If the pay as you go balance on your card is in debit, you must clear it before you next use your Travelcard.
3.6 The Travelcard on your Oyster card is only valid for use by the person for whom it was issued. You may not transfer your Oyster card containing this Travelcard to anyone else in order to travel with it.
3.7 When you use a National Rail service, you should touch your Oyster card on the yellow card reader before you start your journey, at the station you are leaving from; and at the end of your journey, when you arrive at your
destination station. You can still use your Oyster card at stations where there is no yellow card reader or if it is not working provided that your Travelcard is valid for the journey you are making. You may be asked instead to show your Oyster card (and photocard where needed).
3.8 If you are using an Oyster card with a Travelcard season ticket (or tickets) loaded on to it and wish to start your journey from, or travel to, a destination outside the availability of your Travelcard season ticket, or on a route where your season ticket is not valid, you must buy a ticket for your journey. However, if your journey begins and ends at a station within the London National Rail Pay As You Go Area, you can follow the instructions set out in 3.19 and 3.20 provided you have sufficient pay as you go credit on your Oyster card to pay for the additional journey(s). Failure to either buy a ticket or follow the instructions laid out in 3.19 and 3.20 may mean you have to pay a penalty fare or you may be liable to prosecution.
Pay as you go on Oyster
3.19 If you have a valid Travelcard on your Oyster card which only covers the start or end of your journey, or only an intermediate section of it, you can use pay as you go to pay for that part (or those parts) of your journey not covered by your Travelcard, provided that your journey starts, finishes and takes place entirely within the London National Rail Pay As You Go Area. To ensure that you are charged the appropriate pay as you go fare and that the daily cap will, if
appropriate, be applied, you must touch in at the start and touch out at the end of your journey when using pay as you go.
3.20 If you are using an Oyster card with a Travelcard season ticket on it and you are travelling on a Train Company service to a station beyond the availability of your Travelcard season ticket, but within the London National Rail Pay As You Go Area, you must touch in before you start your journey and have sufficient pay as you go credit on your card to cover the cost of the additional travel. If you fail to touch in at the start of your journey, or have insufficient pay as
you go credit, you may be issued with a penalty fare or be prosecuted.
