The Docklands Light Railway is a light metro or light rail system opened on 31 August 1987 to serve the redeveloped Docklandsmarker area of East London, Englandmarker. It covers several areas of London, reaching north to Stratfordmarker, south to Lewishammarker, west to Tower Gatewaymarker and Bankmarker in the City of Londonmarker financial district, and east to Becktonmarker, London City Airportmarker and Woolwich Arsenal.

The DLR is operated under a concession awarded by Transport for London to Serco Docklands Ltd, a joint organisation of the former DLR management team and Serco Group. The system is owned by DLR Limited, part of the London Rail division of Transport for London (TfL), which also manages London Overground and London Tramlink, but not London Underground, which is a separate division of TfL.

In 2006 the DLR carried over 60 million passengers. It has been extended several times, with work and proposals continuously ongoing. Although it has some similarities to other mass transportation systems in London such as the London Underground, DLR trains are not compatible with either the Underground network, Crossrail or the wider railway network in Britain.

History

Origins and development

Tower Gateway station was the DLR's original link to central London.
The docks immediately east of London began to decline in the early 1960s as cargo became containerised. The opening of the Tilburymarker container docks, further east in Essex, rendered them redundant and in 1980 the British government gained control. The Jubilee line of the London Underground opened in 1979 from Stanmoremarker to Charing Crossmarker as the first stage of an intended cross-town tube linemarker beyond Charing Cross to south-east London. Although land, as at Ludgate Circusmarker and Lewishammarker, had been reserved for the second stage, the rising cost led to the project's indefinite postponement in the early 1980s.

The London Docklands Development Corporation (LDDC), needing to provide public transport cheaply for the former docks area to stimulate regeneration, considered several proposals and chose a light-rail scheme using surviving dock railway infrastructure to link the West India Docksmarker to Tower Hillmarker and to run alongside the Great Eastern lines out of London to a northern terminus at Stratford stationmarker where a disused bay platform at the west of the station was available for interchanges with the Central and main lines. Stratford was preferred to a Mile Endmarker alternative, which would involve street running trams and was at variance with the concept of a fully automated railway. The growth brought to Docklandsmarker enabled the Jubilee Line to be extended in 1999 to East Londonmarker by a more southerly route than originally proposed, through Surrey Quays/Docks, Canary Wharfmarker and the Greenwich Peninsulamarker (which was the next regeneration area) to Stratford.

The contract for the initial system was awarded to G.E.C. Mowlem in 1984 and the system was constructed over three years from 1985 to 1987 at a cost of £77 million to complete. The line was opened to the public by Queen Elizabeth II on 30 July 1987, although the inaugural was marred by a technical glitch that saw the Queen briefly trapped inside the train. The first regular passenger services commenced on 31 August of that year.

Initial system (1987–1990)

A first generation DLR EMU crosses West India Dock, September 1987.
The initial system comprised two routes, one from Tower Gatewaymarker to Island Gardensmarker and the other from Stratfordmarker to Island Gardens. Most of the track on these lines is elevated (either on disused railway viaducts or on newly built concrete viaducts) with some use of disused surface-level railway rights of way, although in the original plans for the DLR the lines were intended to be entirely above ground. The trains have always been fully automated and controlled by computer operations and normally have no driver; a Passenger Service Agent (PSA), originally referred to as a "Train Captain", on each train is responsible for patrolling the train, checking tickets, making announcements and controlling the doors. PSAs can also take control of the train in certain circumstances including equipment failure and emergencies.

The system was lightweight, with stations designed for trains with a length of only a single articulated vehicle. The three branches totalled of route, had 15 stations, and were connected by a flat triangular junction near Poplar. Services ran Tower Gateway-Island Gardens and Stratford-Island Gardens, so the north side of the junction was only used for trains to travel to and from the depot at Poplar, not in regular passenger service. The first stations were mostly of a common design and constructed from standard components. A characteristic of them was a relatively short half-cylindrical glazed blue canopy to provide shelter from the rain. All stations were above ground and were generally unstaffed (stations located below ground built during later extensions were required by law to be staffed, in case evacuation is needed).

First stage extensions (1991–1994)

The initial system had little capacity as the Docklands area very quickly developed into a major financial centre and employment zone, increasing the demand on the fledgling commuter network. In particular Tower Gateway, at the edge of the City of Londonmarker, attracted criticism for its poor connections. This is partly because the system was not expected by much of its management to achieve such high levels of usage. Plans were developed to extend to Bank and to Beckton before the system opened to the public. As a result all stations and trains were extended to two-unit length, and the system was taken into the heart of the City of London to Bank underground stationmarker through a tunnel which opened in 1991. This extension diverged from the initial western branch, leaving Tower Gateway stationmarker on a stub. The original trains, not suitable for use underground, became obsolete. (see the Rolling Stock section below, and the main article Docklands Light Railway rolling stock).

As the Canary Wharfmarker office complex grew, Canary Wharf DLR stationmarker was redeveloped from a small wayside station to a large one with six platforms serving three tracks, with a large overall roof and fully integrated into the malls below the office towers. The original DLR station was never completed and was dismantled before the line officially opened, although the automatically-operated trains continued to stop at its location.

The areas in the east of Docklandsmarker needed better transport connections to encourage development and so a fourth branch was opened in 1994, from Poplarmarker to Becktonmarker via Canning Town transport interchangemarker, running along the north side of the Royal Docks complex. Initially it was thought likely to be underutilised, due to sparse development. Several proposals were made for the Blackwall Area. As part of this extension, one side of the original flat triangular junction was replaced with a grade-separated junction west of Poplar, and a new grade-separated junction was built at the divergence of the Stratford and Beckton lines east of Poplar. Poplar station was rebuilt to give cross-platform interchange between the Stratford and Beckton lines.

Second stage extensions (1996–1999)

Early in the DLR operation, Lewishammarker council commissioned a feasibility study into extending the DLR under the River Thames. This led the council to advocate an extension to Greenwichmarker, Deptfordmarker and Lewisham. In its early days, the DLR had been criticised by experts as being "the wrong type of system for Docklands' needs", in comparison with the Underground line proposed in the 1980s. However, the ambitions of operators were supported by politicians in Parliament, including then Labour Deputy Prime Minster John Prescott and Lord Whitty, and by 1996 construction work on the line commenced as proposed.

On 3 December 1999 the Lewisham extension opened to the public. It left the original Island Gardens route south of the Crossharbour turn-back sidings, dropped gently to Mudchute where a street-level station replaced the high-level one on the former London & Blackwall Railway viaduct and then entered a tunnel following the line of the viaduct and reached a new shallow subsurface station at Island Gardens, accessed by stairs. The line crossed under the Thames to a station in the centre of Greenwich and then surfaced at the main-line Greenwich stationmarker with cross-platform interchange between the northbound DLR track and the city-bound main line. Then the line snaked on a concrete viaduct to Deptford, Elverson Road station at street level, close to Lewisham town centre and terminated in two platforms between and below the main-line platforms at Lewisham railway stationmarker, which is near the town shopping centre, with bus services stopping directly outside the station. The Lewisham extension quickly proved profitable.

Third stage extensions (2004–2009)

The next series of developments of the DLR were aided by a five year program of investment for public transportation across London that was unveiled by Mayor of London Ken Livingstone on 12 October 2004. On 2 December 2005, a new eastward branch, along the southern side of the Royal Docksmarker complex, opened from Canning Town to King George Vmarker via London City Airportmarker.

A further extension from King George Vmarker to Woolwich Arsenalmarker opened on 10 January 2009, with the terminal station built at or close to the planned future stop on the Crossrail line to Abbey Wood via West India and Royal Docks. Government approval for the project was given in February 2004, with a projected cost of £150 million, due to a required second DLR tunnel crossing of the River Thames, met by Private Finance Initiative funding. Construction began in June 2005, the same month that the contracts were finalised, and the tunnels were completed on 23 July 2007, and officially opened by Boris Johnson, Mayor of London on 12 January 2009. Following completion this project was shortlisted for the 2009 Prime Minister’s Better Public Building Award.

The original Tower Gateway station was closed in mid-2008 for complete reconstruction. The two terminal tracks either side of a somewhat narrow island platform were replaced by a single track between two platforms, one for arriving passengers and the other for those departing. The station reopened on 2 March 2009.

Recent developments

As part of an upgrade to the system to allow three-car trains, some strengthening work was necessary at the Delta Junction north of West India Quaymarker. It was decided to include this in a plan for further grade-separation at this critical junction to eliminate the conflict between services to Stratford and from Bank. Following this, a new timetable has been introduced with improved frequencies in peak hours. The new grade-separated route from Bank to Canary Wharf is only used at peak times as it bypasses West India Quay station. Work on this project proceeded concurrently with the three-car upgrade work and the flyunder, and the improved timetable came into use on 24 August 2009.

Current system



The DLR is now long, with 40 stations along the route. There are five branches: to Lewishammarker in the south, to Stratfordmarker in the north, to Becktonmarker and to Woolwich Arsenalmarker in the east, and to Central London in the west, splitting to serve Bankmarker and Tower Gatewaymarker. Although the layout allows many different combinations of routes, at present the following four are operated in normal service:
  • Stratford to Lewisham
  • Bank to Lewisham
  • Bank to Woolwich Arsenal
  • Tower Gateway to Beckton
There is an additional shuttle service from Canning Town to Prince Regent, operated when exhibitions are in progress at the ExCeL exhibition centremarker, to double the normal service. These trains reverse direction in the eastbound platform at Canning Town and on a crossover at the high point where the line crosses the Connaught Crossing road bridge between Prince Regent and Royal Albert stations.

At other stations trains reverse direction in the terminal platforms, except at Bank where there is a reversing headshunt beyond the station. Some peak hour trains on the Stratford line turn back at Crossharbourmarker rather than continuing to Lewisham. There are also occasional trains from Tower Gatewaymarker to Crossharbour and Lewishammarker. Every train serves every station on its route; no stations are skipped. During the substantial long-term works for various DLR extension projects, a range of other routes may be operated at weekends, such as Beckton to Lewisham if the Bank branch is closed.

The northern, southern and south-eastern branches terminate at the National Rail (main line) stations at Stratford, Lewisham and Woolwich Arsenal respectively. Other direct interchanges between the DLR and National Rail are at Limehousemarker and Greenwich.

Depots

There are two operating depots, at Poplar and Beckton, both with maintenance workshops and extensive open-air stabling sidings. The Poplar depot is alongside the north side of the Stratford line east of the station, while the Beckton depot is to the east of the line on a long spur north-east of Gallions Reach station, and is only visible in the distance from the line. The small diesel locomotives used for track maintenance tasks are normally visible at Poplar depot. Between 2005-2006 Beckton depot received extensions and upgrades, including more sidings and improved signalling.

Stations

Many DLR stations are elevated, with others at street level, in a cutting, or underground. Access to the platforms is mostly by staircase and lift; few stations have escalators. From the outset the network has been fully accessible to wheelchairs; much attention was paid to quick and effective accessibility for all passengers. The stations have high platforms, matching the floor height of the cars, allowing easy access for passengers with wheelchairs or pushchairs.

Most of the stations are of a modular design dating back to the initial system, extended and improved over the years. This design has two side platforms, each with separate access from the street, and platform canopies with a distinctive rounded roof design. Stations are unstaffed, except the underground stations at Bankmarker, Island Gardensmarker, Cutty Sarkmarker and Woolwich Arsenal (for safety reasons), and a few of the busier interchange stations. Canning Town, interchange with the Jubilee underground line, along with the exhibition centre stations at Custom House and Prince Regent, are normally staffed on the platform whenever there is any significant exhibition at the ExCeL exhibition centre.

DLR art

On 3 July 2007, DLR officially launched an art programme called DLR Art, similar to that on the London Underground, Platform for Art (which has since been renamed "Art on the Underground"). Alan Williams was appointed to produce the first temporary commission, called "Sidetrack", which portrays the ordinary and extraordinary sights often unfamiliar to passengers, on the system and was displayed throughout the network.

Fares and ticketing

A train awaits departure from Woolwich Arsenal.
Ticketing on the DLR is part of the London fare zone system, and Travelcards that cover the correct zones are valid. There are one-day and season DLR-only "Rover" tickets available, plus a one-day DLR "Rail and River Rover" ticket for use on the DLR and on City Cruises river boats. Oyster Pre-Pay is also available; passengers need to both touch in and touch out on the platform readers or pass through the automatic gates. Tickets must be purchased from ticket machines at the entrance to the platforms, and are required before the passenger enters the platform. There are no ticket barriers in DLR-only stations, and correct ticketing is enforced by on-train checks by the PSA. There are barriers at Bankmarker, Canning Townmarker, Woolwich Arsenalmarker and Stratfordmarker, where the DLR platforms are within the barrier lines of a London Underground or National Rail station.

Although Oyster cards are TfL's preferred method of ticketing on the DLR, there are some differences in the implementation compared to the Underground. Stations are simplistic and most do not have ticket gates. There have been criticisms that the Oyster touch in/out units are not readily apparent, particularly to infrequent passengers, as they have been sited where there is an electrical supply, which may not be the most obvious point for users. London City Airport station, which is used by many travellers from overseas, is a particular example of this. Passengers who do not touch both in and out on each journey end up with a £4 charge as a result of incomplete entries on their Oyster card. The old ticket machines provided at each DLR station neither sold new Oyster cards nor allowed top-up of existing cards, although new machines have recently been installed across the network which allow this. There was a significant failure of the Oyster card system on 14 July 2008 which caused havoc to commuters trying to pay for their journeys using the card.

Performance

The rapid expansion, with multiple extensions, of the Docklands Light Railway demonstrates the success of the system. The DLR is now used by up to 100,000 people every day. Within a year of launch, annual passenger numbers were 17 million. By 2009 this had increased to 64 million While the first five years were plagued with unreliability and operational problems, the system has become highly reliable.

The Stakeholder Relations Manager for the Olympic Delivery Authority, Stephen, said:

The local population are overwhelmingly positive about the DLR: in 2008, 87% were in favour of the DLR around North Woolwich.

Criticisms

The Docklands Light Railway has generally been very successful, as with many other light rail systems built in the last few years. However, the DLR has been criticised as having been designed with insufficient capacity to meet the demand that quickly arose. The level of demand had been greatly underestimated. In 1989 such criticism was aimed at GEC, a major contractor for the DLR construction. There remains debate in the UK as to whether light rail is cost effective, with criticism focused on alleged low ridership and cost overruns.

Although DLR claims to be highly accessible, bicycles are not allowed on trains (except for folding bikes). One notable incident involved a station manager refusing to allow a train to leave before several triathlon competitors had been made to leave the vehicle. DLR say this is because if evacuation of a train is required, they would slow down the process. Also, DLR cars are not designed with bicycles in mind - if they were allowed, they would easily obscure doors and emergency exits.

Accidents and incidents

Overrun of station buffers

Island Gardens DLR station before being rebuilt
On 10 March 1987, before the railway opened, a test train crashed through station buffer stops at the original high-level terminus Island Gardensmarker station and was left hanging from the end of the elevated track. The accident was caused by unauthorised tests being run before accident-preventing modifications had been installed. The train was being driven manually at the time.

Service difficulties with the Royal train

In July 1987, a series of minor incidents marred the operation of the royal train (number E2R) carrying Queen Elizabeth II as part of the ceremonies marking the opening of the line. The train had been manually dispatched from its starting point at Island Gardens station five minutes early because of the early arrival of the royal party. The train was on automatic control and so, being ahead of schedule, was held at the next station (Mudchute) for a few minutes before the driver reverted to manual control "to speed the Royal passage" and continued on to Poplar station, where the royal party were to disembark. A member of the royal security detail used the emergency exit to leave the train before it had stopped, causing the train to make an emergency stop short of its normal position and out of range of the docking beacon that marked its arrival point. The train doors would not open, impeding the Queen's exit for several minutes.

Collision at West India Quay bridge

On 22 April 1991, two trains collided at a junction on the West India Quaymarker bridge during morning rush hour, requiring a shutdown of the entire system and evacuation of the involved passengers by ladder. One of the two trains was travelling automatically, operating without a driver, while the other was under manual control.

South Quay bombing

On 9 February 1996, the Provisional Irish Republican Army blew up a lorry under a bridge near South Quaymarker, killing two people and injuring many others. This number would have been higher if not for advance warning. The blast did £85 million damage and marked an end to the IRA ceasefire. Significant disruption was caused to DLR services, and a train was left stranded at Island Gardens station, unable to move until the track was rebuilt.

Rolling stock



The DLR is operated by high-floor, bi-directional, single-articulated electrical multiple unit cars. Each car has four doors on each side, and two cars make up each train (upgrades to 3-car trains are in process). There are no driver's cabs because normal operations are automated. Instead, the cars have a small driver's console (concealed behind a locked panel at each car end) from which the PSA can drive the car. 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 unusual forward (or rear) view for passengers. The current stock has a top speed of .

Despite having high floors and being highly automated, the cars are derived from a German light-rail design intended for use in systems with street running. All the cars that have operated on the system to date look similar, but there have been several different types, some still in service and others sold to other operators. New units (B2007) for the Docklands Light Railway were purchased from Bombardier in 2005 and delivered between 2007 and 2009.

Ride Comfort

On certain sections of track, the quality of the ride is significantly inferior to that on national rail network or London Underground rolling stock, due to excessive hunting oscillation. Passengers can be thrown quite violently from side to side with a frequency of about 1 Hertz.

Signalling technology

Originally the DLR used signalling based on a fixed-block technology developed by GEC-General Signal and General Railway Signalmarker. This was replaced in 1994 with a moving-block system developed by Alcatel, called SelTrac. The SelTrac system was bought by Thales in 2007 and current updates are being provided by Thales Signalling Solutions. The same technology is used for some other rapid transit systems, including Vancouver's SkyTrain, Toronto's SRT, San Francisco's Municipal Railway (MUNI) and Hong Kong's MTR, and is currently being adopted by the Jubilee line on London Underground. Transmissions occur between each train's onboard computer and the control centre at Poplar. If this link is broken, the train stops until it is authorised to move again. If the whole system fails the train can run at only . for safety until the system is restored. Emergency brakes can be applied if the train breaks the speed limit during manual control, or if the train leaves the station when the route has not been set.

Future developments

With the development of the eastern Docklands as part of the ‘Thames Gatewaymarker’ initiative and London’s successful bid for the 2012 Summer Olympics, several extensions and enhancements are under construction, being planned or being discussed.

Upgrading entire system to three-car trains

Status — Under construction
The capacity of the entire system is being increased by upgrading to take three-car trains. The alternative of more frequent trains was rejected as the signalling changes needed would have cost no less than upgrading to longer trains and with fewer benefits. The railway was originally built for single-car operation, and the upgrade requires both strengthening viaducts to take the heavier longer trains and lengthening many platforms; however recent extensions were already built to take three-car trains. It has been suggested that the extra capacity will be useful during the 2012 Summer Olympics, which are expected to increase the usage of London's transport network. The main contractor selected to carry out the expansion and alteration works on the DLR network was Taylor Woodrow.

A few stations (Elverson Road, Pudding Mill Lane, Royal Albert, Gallions Reach, Cutty Sark) are not planned to be extended to accept three-car trains; such extension may be impossible in some cases. Selective Door Operation will be used, with emergency walkways in case a door fails to remain shut. For instance Cutty Sark stationmarker is underground, and both costs and the risk to nearby historic buildings prevent platform extension. The tunnel there was built with an emergency walkway throughout its length. Additional work beyond that needed to take the three-car trains is being carried out at some stations. This includes replacing canopies with more substantial ones along the full platform length. A new South Quay stationmarker has been built to the east of the former location as nearby curves precluded lengthening. Mudchutemarker now has a third platform and all its platforms have full-length canopies. Tower Gatewaymarker was closed until March 2009 and re-opened as a single track three-car terminus with two platforms - one side for boarding and the other for alighting.

For this upgrade DLR purchased an additional 31 cars compatible with existing rolling stock to meet the demand for more train units. The works were originally planned as three separate phases: Bank-Lewisham, Poplar-Stratford, and finally the Beckton branch. The original £200m works contract was awarded on 3 May 2007. Work started in 2007 and the Bank-Lewisham phase was originally due to be completed in 2009. However, the work programme for the first two phases was merged and both are now due to be complete in early 2010. Funding to upgrade the Becktonmarker branch was not secured until December 2008, and the work will not be completed until 2011.

Stratford International extension/North London Line conversion

Status — Under Construction — opening mid 2010
An extension being built from Canning Town to the new Stratford International stationmarker takes over part of the North London Line and will link the Docklands area with domestic and international high-speed services on High Speed 1. Stratford International was constructed in 2006, and opened on 30 November 2009 when Southeastern high speed trains started calling. It is an important part of the transport improvements for the 2012 Olympic Games, much of which will be held on a site adjoining Stratford International. North London Line passengers towards North Woolwich will be displaced onto the DLR extension and the Woolwich Arsenal branch. The first contract for construction work was awarded on 10 January 2007 and construction work started in mid 2007. The DLR extension is due to open in mid 2010.

Former NLL stations transferring to DLR are:

New stations for DLR are:

At Stratford new platforms have been built for the North London Line, leaving its original platforms (1 and 2) and moving to a separate location at the northern end of the station. The old platforms are available for the DLR and will be renumbered platforms 16 and 17. Interchange between the two DLR routes will be possible, although their platforms are widely separated and at different levels. There will be no track connection between the two routes. As part of the Transport & Works Act (TWA) application, Royal Victoriamarker station on the Beckton branch will be extended to accommodate three-car trains, with a third platform to enable trains to reverse there, using land released by the closure of this section of the parallel North London line. A partly grade-separated junction built south of Canning Town will prevent conflicting movements on the existing Bank branch and the new Stratford branch going to and from the Beckton route and the Woolwich Arsenal route.

Limehouse station interchange

Status — Now Open
View of Limehouse DLR station
Limehouse stationmarker, which is on a viaduct, is a useful interchange for Essex commuters who work in the Canary Wharf area. Currently it has an awkward interchange between the DLR platforms and the National Rail platforms served by c2c as passengers have to pass down and then up flights of stairs. To remedy this, at least in part, a bridge is being built to connect the westbound c2c platform with the adjacent eastbound DLR platform. It was originally due for completion by the end of 2008 but work is ongoing and now due for completion in November 2009. At the same time as the bridge was being built, other improvements were made, including readying the station for three carriage operations on the DLR and the construction of additional lifts and stairways for platform access.

Works contingent on Crossrail

Status — Approved
When Crossrail is built, one of its tunnel portals will be on the current site of Pudding Mill Lane station. The DLR will be diverted between City Mill River and the River Lea onto a new viaduct to be built further south, including a replacement station. The opportunity may be taken to eliminate the only significant section of single track on the system, between Bow Church and Stratford, although there is no provision for works beyond the realigned section in the Crossrail Act.

Crossrail will interchange with the DLR at Custom House, at Stratford and at West India Quay with Crossrail's Canary Wharfmarker station. Custom Housemarker will be completely rebuilt. If a Crossrail station is built in the London City Airportmarker area, a new DLR station could be built alongside (see Connaught Road/Silvertown Interchange station section below).

Long term proposals

Dagenham Dock extension



Status — Under consideration (as of October 2009)
This proposed extension from Gallions Reachmarker to Dagenham Dockmarker via the riverside at Barking would connect the Barking Reach area, a formerly industrial area now due to be a major redevelopment as part of the London Riverside, with the Docklands. Docklands Light Railway - Dagenham Dock: Key Project Milestones Transport for London It would cover major developments at Creekmouth, Barking Riverside, Dagenham Dock Opportunity Area, and five stations are planned, at Beckton Riverside station, Creekmouth, Barking Riverside, Goresbrook (formerly Dagenham Vale) and Dagenham Dock. The extension is key if English Partnerships' plan is to work. As shown in DLR's first consultation leaflet, there are proposals for the DLR to extend further than Dagenham Dockmarker, possibly to Dagenham Heathwaymarker or Rainhammarker.Transport for London - DLR Dagenham Dock extension preferred alignment (February 2008)

Construction was not expected to start until 2013 and the earliest expected completion date was 2017. However the Financial crisis of 2007–2009 meant that TfL requested a delay to the public enquiry whilst funding was clarified. Given that the purpose of the extension was to serve as-yet unbuilt homes it became very difficult to predict timescales for this project. The project has been reported to have been cancelled by the Mayor of London Boris Johnson as a cost cutting measure, although there have been calls for this to be reconsidered, the extension being regarded by Barking and Dagenham council as essential to regenerating the area.

As of October 2009, the plan seems to be once again under consideration. The Mayor's Transport Strategy states that the Mayor, through Transport for London, will investigate the feasibility of the extension to Dagenham Dock as part of the housing proposals for Barking Riverside.

Thames Wharf station

Status — On hold
This station had been included as potential future development on the London City Airport extension since it was first planned. It would be between Canning Townmarker and West Silvertownmarker, due west of the western end of Royal Victoria Dockmarker. Since the station's intended purpose is to serve the surrounding area (currently a mix of brownfield and run-down industrial sites) when it is regenerated, the development is indefinitely on hold due to the area being safeguarded for the Silvertown Link, a new Thames river crossing that has been proposed but currently has no timetable for implementation.

Connaught Road/Silvertown Interchange station

Status — Proposed
A site near to London City Airportmarker has been identified as a possible additional station on the London City Airport extension. It would be a possible interchange with Crossrail between London City Airportmarker and Pontoon Dockmarker. However, no plans have emerged as to when this station is to be planned and built. The original extension was designed to allow a station to be built here. It may be located south of the Connaught Crossing.

Victoria/Charing Cross extension

Docklands Light Railway logo as it appears on the Tube map
Status — Proposed — 2006
In February 2006 a proposal to extend the DLR to Charing Cross stationmarker from Bankmarker DLR branch was revealed. The idea, originating from a DLR "Horizon Study", is at a very early stage at the moment, but would involve extending the line from Bank in bored tunnels under Central London to the Charing Cross Jubilee line platforms, which would be brought back to public use. These platforms are now on a spur off the current Jubilee line and are not used by passenger trains. It has since been revealed that a proposed route as far as Victoria stationmarker will be investigated.

While not confirmed it is probable that the scheme would also use the existing overrun tunnels between the Charing Cross Jubilee platforms and a location slightly to the west of Aldwychmarker. These tunnels were intended to be incorporated into the abandoned Phase 2 of the Fleet Line (Phase 1 became the original Jubilee Line, prior to the Jubilee Line Extension). However they would need some enlargement because DLR gauge is larger than tube gauge and current safety regulations would require an emergency walkway to be provided in the tunnel.

Two reasons driving the proposal are capacity problems at Bank, having basically one interchange between the DLR and the central portion of Underground, and the difficult journeys faced by passengers from Kentmarker and South Coast between their rail termini and the DLR. Intermediate stations would be at Ludgate Circusmarker and Aldwychmarker, for future connection with the Cross River Tram.

Euston/King's Cross extension

Status — Proposed
During the last Horizon study, a possible extension was considered from Bank towards Eustonmarker or King's Crossmarker. The main benefit of such an extension would be to broaden the available direct transport links to the Canary Wharf site. It would create a new artery in central London and help relieve the Northern and Circle lines. There are no official plans for possible stations except towards Farringdonmarker, possibly using some of the disused Thameslink infrastructure.

Lewisham to Catford extension

Status — Proposed — 2026
This extension was looked at during the latest Horizon Study. The route would follow the Southeastern line and terminate between Catford stationmarker and Catford Bridge stationmarker. It has been seen as attractive to the district, as has the current terminus at Lewisham which was built in an earlier extension. However, early plans showed problems due to Lewisham DLR station being only marginally higher than the busy A20 road which impedes any proposed extension. The plan is however being revised. When the Lewisham extension was first completed there were proposals to continue further to Beckenhammarker to link it up with the Tramlinkmarker system. However, the way in which Lewisham DLR was built impedes this possible extension and it would prove costly to redevelop.

Other locations

The Parliamentary Transport Select Committee has reviewed light rail on several occasions.

Given the public and official perceived success of the Docklands system (born amongst much scepticism in the 1980s) it is not surprising there has been at least one proposal to duplicate that success elsewhere, using the same, now proven, technology. The North and West London Light Railway is an outline and unfunded plan for an orbital railway on the other side of London. It has gathered some degree of local authority support, partly because there are large London Plan brownfield development sites in that part of the capital, with consequent transport requirements to be satisfied.
