Docklands Light Railway rolling stock is the passenger trains and service vehicles (collectively known as 'rolling stock') used on the Docklands Light Railway (DLR), which serves the London Docklands area in the east of London.
The passenger stock consists of high-floor, bi-directional, single-articulated electrical multiple units. The trains are formed from sets of 2 semi-permanently connected cars, although it is planned to increase these to three-car sets. The trains are fully automated and have no driver, but a Passenger Service Agent (PSA) is in attendance in each train and can take control at a driver's console if required.
As of 2009, there are three different types of DLR rolling stock, but only two of them (the B90/B92/B2K fleet and the B07/09 fleet) are in operation; the original P86/P89 stock having been withdrawn in 1991/1995 and sold to a German operator.
