Ticketing
Tickets for trains between Fenchurch Street and Upminster are inter-available with London Underground services between Tower Hill and Upminster, at Transport for London fares. All other journeys are priced by c2c. Oyster card pay-as-you-go has been available since 2004 between Fenchurch Street/Liverpool Street and Upminster. It was extended to Rainham in 2008 and beyond Travelcard Zone 6 to Grays in January 2010. Oyster cards may be purchased or topped up at some c2c stations that are not also London Underground stations, including Chafford Hundred, Grays, and Purfleet. c2c ticket machines in the Oyster PAYG area have been upgraded so they can read Oyster cards.
