Docklands Light Railway rolling stock

The DLR is equipped with 149 high-floor bi-directional single-articulated electric multiple units (EMUs). DLR trains are highly automated, running segregated from traffic powered by a bottom-contact third rail. The automation system is a GoA3 driverless system, which requires a Passenger Service Agent (PSA) to manually open and close the doors and, when necessary, manually drive the train. Consoles at each door opening allow a PSA to control door closure and make announcements whilst patrolling the train. With the absence of a driver's position, the fully glazed car ends provide a forward and rear view for passengers.^[1]

Four generations of DLR train have been used – currently in use are the B90, B92 and B2K stock trains dating from the 1990s and early 2000s, and the B07 stock trains from the late 2000s.^[1] The B90/B92/B2K stock and the B07 stock form sets of two or three semi-permanently connected cars, the increase to three-car trains introduced on the busiest routes since 2010, following substantial platform extension works.^[2] The original P86 and P89 stock trains used in the late 1980s and early 1990s were sold to the Essen Stadtbahn in Germany, following the decommissioning of the original signalling system in 1995.^[3]^[4]

In the late 2010s, TfL ordered new trains from Construcciones y Auxiliar de Ferrocarriles (CAF) to replace the existing B90/B92/B2K stock and provide additional capacity on the network.^[5] The B23 trains entered service in 2025, but were removed from service two months later due to braking issues.^[6]
