B92 stock train 57 arrives at Canary Wharf
The
Docklands Light Railway (DLR) is operated by high-floor, bi-directional, single-articulated cars with four doors on each side, with each train normally composed of two cars. The cars have no driver’s cab, although there is a small driver’s console concealed behind a locked panel at each car end from which the passenger service agent (PSA) can drive the car when necessary. Other consoles at each door opening allow the PSA to control door closure and make announcements whilst patrolling the train. Because of the absence of a driver’s position, the fully glazed car ends provide an excellent forward (or rear) view for passengers.
Despite having high floors and being highly automated, the cars are derived from a
German light-rail design intended for use in systems with elements of street running. All the cars that have operated on the system look similar, but there have been five separate types, of which three are still in operation on the DLR. A further car type, with quite different styling, is due to be introduced in 2007.
Withdrawn rolling stock

A P89 stock train running in Essen, Germany
The fleet for the
1987 opening consisted of 11
light-rail vehicles built in
1986 by
LHB in
Germany and numbered 01 to 11. These were referred to as 'P86 stock', with P referring to
Poplar depot, where they were maintained. These cars were built for the initial above-ground system and, because of the lack of appropriate fire-proofing, were not allowed to operate on the tunnelled extension to
Bank. Because of this, and because adaptation to a new signalling system was too costly, these cars were sold in
1991 to
Essener Verkehrs-AG of
Essen, Germany, where they were extensively rebuilt and put into service on its
Stadtbahn between
1994 and
1998. Originally, they retained DLR colours and were limited to route U11, but after a further modification programme started in
2005, trains are appearing in a yellow livery and are used on all routes.
In
1989,
BREL supplied another ten LRVs, numbered 12 to 21. These share the characteristics of the original P86 stock. They were thought equipped with sufficient fire-proofing to operate through the tunnels of the Bank extension. These were designated 'P89 stock' and remained in operation on the DLR until the middle of the 1990s. They were also sold to Essen, where they entered service between
1999 and
2004 after major modifications had been carried out. They are now painted yellow and blue and are used on all routes of the Essen Stadtbahn network.
As the Essen Stadtbahn does not use fully automated driving, and uses
overhead power collection, the modifications to both sets of cars involved fitting driver's cabs and
pantographs.
Current rolling stock
Further vehicles were required as the network grew and as the original P86 and P89 cars had to be replaced due to their unsuitability for the changed system conditions.
Bombardier built 23 vehicles of 'B90 stock' in
1991, 47 vehicles of 'B92 stock' between
1993 and
1995 and 24 vehicles of 'B2K stock' in
2001 and
2002. When new the B2K stock differed from the earlier vehicles in appearance due to doors and handrails painted in contrasting colours to their surroundings. They are also fitted with internal
LCD display screens. These differences were all mandated by the
Rail Vehicle Access Regulations (RVAR) of the
Disability Discrimination Act (DDA), which were not in force when the older stocks were built.
The B in the type codes refers to
Beckton depot, where they are primarily maintained. They are of a common design and can be operated interchangeably in trains of two. All of them remain in service.

The interior of B92 stock train 49
The DLR fleet at the end of
2004 was:
★ 22–44:
Bombardier B90, built
1991
★ 45–91:
Bombardier B92, built
1993–
1995
★ 92–99, 01–16:
Bombardier B2K, built
2001–
2002
DLR cars had a common livery of red, blue, and white upon delivery. Over the years, several vehicles have received all-over advertising livery. A new livery of turquoise and blue was tested on B92 car 45 in the mid-1990s, but it was not adopted, and the car reverted to standard livery a few years later. Refurbishment of the B90 cars started in
2004, with the completed trains re-entering service in a new livery of red and blue with grey doors.
All the current stocks are currently being refurbished with a new livery and redesigned interior.
Future rolling stock
In May 2005, Bombardier announced that they would be providing a further 24 vehicles of a new design, which they consider superior to the current fleet. The new cars, needed for coming extensions and three-car service on the Bank–Lewisham route, are to be delivered between May
2007 and September
2008.
[1] It is expected these vehicles will be designated 'B07 stock'.
In June 2006 another 31 vehicles were added to this order, partly funded by the
Olympic Delivery Authority, to be delivered by 2009.
[2] If previous naming conventions are applied, then it is expected these additional vehicles will be known as 'B09 stock'.
