Oyster CardsOyster PAYG is now valid on Southeastern High Speed services between London St. Pancras and Stratford International. Oyster is also valid on Docklands Light Railway services.
Stratford International is a National Rail station in Stratford and a separate Docklands Light Railway (DLR) station nearby, located in East Village in London. Despite its name, no international services stop at the station; plans for it to be served by Eurostar trains never came to fruition.

With high speeds of up to 140 mph using the modern Javelin trains, this line provides a highly convenient commuter service from Kent to the city of London.
