[[File:Limehouse station MMB 11 DLR 62.jpg|thumb|The [[London, Tilbury and Southend line]] (foreground), operated by [[c2c]], runs alongside the DLR (behind the fence) from Limehouse to Tower Gateway.]]
The northern, southern and south-eastern branches terminate at the National Rail stations at Stratford, Stratford International, Lewisham and Woolwich Arsenal. Other interchanges with National Rail are at [[Limehouse station|Limehouse]], [[Greenwich station|Greenwich]] and [[West Ham station|West Ham]], while out-of-station interchanges for [[Oyster card]] holders are available between Shadwell DLR station and the [[Windrush line]] station of the [[Shadwell railway station|same name]], and between Fenchurch Street and the DLR's western termini of Tower Gateway and Bank.<ref>{{cite web |title=OSI List |date=October 2014 |url=http://www.oyster-rail.org.uk/osi-list/ |website= oyster-rail.org.uk |access-date=14 April 2015 |url-status=live |archive-url=https://web.archive.org/web/20150320010931/http://www.oyster-rail.org.uk/osi-list |archive-date=20 March 2015}}</ref>

Between Limehouse and Tower Gateway, the DLR runs parallel to the [[London, Tilbury and Southend line]].

At peak times, these same services run, but with the frequency increased by 25 per cent. Additionally, in the morning peak, alternate Stratford{{snd}}Canary Wharf services extend to Lewisham.

At terminal stations, trains reverse direction in the platforms, except at Bank where there is a reversing [[headshunt]] in the tunnel beyond the station. During service disruption or planned engineering work, trains can also turn back at {{stl|DLR|Crossharbour}} and {{stl|DLR|Mudchute}}. There is also capability for an additional shuttle from Canning Town to Prince Regent when exhibitions are in progress at the [[ExCeL London|ExCeL exhibition centre]], although this is not supported by any additional turnback infrastructure. Trains serve every station on the route, but trains from Bank to Lewisham do not call at {{stl|DLR|West India Quay}} because they are routed along the diveunder track to avoid junction conflicts. When required, such as during engineering works or for special events, other routes may be operated, such as Beckton to Lewisham if the Bank and Tower Gateway branch is closed.

====Future services====
The new rolling stock to be introduced from 2024 onwards will support service improvements.<ref name = improv />

===Stations===
[[File:DLR Westferry aerial view.jpg|upright|thumb|An eastbound train leaving Westferry Station]]
{{Main|List of Docklands Light Railway stations}}
Most stations are [[Elevated railway|elevated]], with others at street level, in cutting or underground. Access to the platforms is mostly by staircase and lift, with escalators at some stations. From the outset the system has been fully accessible to wheelchairs; much attention was paid to quick and effective accessibility for all passengers.<ref name=autogenerated1>{{cite web |url=http://www.tfl.gov.uk/gettingaround/transportaccessibility/2986.aspx |title=DLR was the first fully accessible railway in the UK, making access much easier for everyone |publisher=Transport for London |access-date=4 March 2012 |url-status=live |archive-url=https://web.archive.org/web/20120530014302/http://www.tfl.gov.uk/gettingaround/transportaccessibility/2986.aspx |archive-date=30 May 2012 }}</ref> The station platforms match the floor height of the cars, giving level access for passengers with wheelchairs or pushchairs.<ref name=":102" />

Most stations are of a modular design dating back to the initial system, extended and improved with two side platforms, each with separate access from the street, and platform canopies, although few examples remain of the original, distinctive rounded roof design. Stations are unstaffed, except the underground stations at {{stl|London Underground|Bank}}, [[Stratford International railway station|Stratford International]] and [[Woolwich Arsenal station|Woolwich Arsenal]] for safety reasons, a few of the busier interchange stations, [[Canning Town Station|Canning Town]], [[West Ham Station|West Ham]], and City Airport, which has a ticket office for passengers unfamiliar with the system.  Canning Town, Custom House and Prince Regent are normally staffed on the platform whenever there is a significant exhibition at the [[ExCeL]] exhibition centre.

On 3 July 2007, DLR officially launched<ref>{{cite press release|publisher=Transport for London |date=3 July 2007 |url=http://www.tfl.gov.uk/static/corporate/media/newscentre/archive/5426.html |title=Docklands Light Railway draws up public arts strategy |access-date=4 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120425190215/http://www.tfl.gov.uk/static/corporate/media/newscentre/archive/5426.html |archive-date=25 April 2012 }}</ref> an art programme called DLR Art,<ref>{{cite web |url=http://www.dlrart.co.uk/ |title=The DLR Public Arts Programme |publisher=DLR Art |access-date=5 August 2010 |url-status=live |archive-url=https://web.archive.org/web/20120509043254/http://www.dlrart.co.uk/home/ |archive-date=9 May 2012 }}</ref> similar to that on the London Underground, [[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.<ref>{{cite web|url=http://www.dlrart.co.uk/projects/view.asp?id=8|title=Alan Williams&nbsp;– Sidetrack|publisher=Docklands Light Railway|access-date=25 June 2009|url-status=dead|archive-url=https://web.archive.org/web/20090829061702/http://www.dlrart.co.uk/projects/view.asp?id=8|archive-date=29 August 2009}}</ref>

===Fares and ticketing===
[[File:Unit 90 at Woolwich Arsenal DLR.JPG|thumb|A train awaits departure from Woolwich Arsenal.]]
The system is part of the [[London Underground ticketing#Fare zones|London fare zone]] system, and [[Travelcard]]s that cover the appropriate zones are valid. Tickets can be purchased from ticket machines at the entrances to platforms, and are required before accessing the platform. Passengers using [[Oyster card|Oyster]] pay-as-you-go<ref>{{cite web|url=http://www.studentjetpacks.com/jetpacks_london_oystercard.asp|title=London jetpack: London Oyster travelcard|publisher=studentjetpacks.com|access-date=21 June 2009|url-status=dead|archive-url=https://web.archive.org/web/20120530020421/http://studentjetpacks.com/jetpacks_london_oystercard.asp|archive-date=30 May 2012}}</ref> and [[Transport for London#Contactless payments|contactless]] bank-cards need to touch both in and out of the system using card readers on automatic gates and platforms. There are no ticket barriers at DLR-only stations:<ref>{{Cite news |title=Tube errors may cost you dear |newspaper=The Times |date=5 January 2004 |location=London |first1=Ben |last1=Webster |first2=Andrew |last2=Clennell}}</ref> correct ticketing is enforced by random on-train inspections by Passenger Service Agents (PSAs). There are barriers at [[Bank–Monument station|Bank]], {{stl|London Underground|Canning Town}}, West Ham and {{stl|London Underground|Stratford}}, where the DLR platforms are within a [[London Underground]] or [[National Rail]] barrier line. There are also ticket barriers at [[Woolwich Arsenal station|Woolwich Arsenal]], which are the only barriers staffed by DLR staff; at this station passengers can pass between the DLR and [[Southeastern (train operating company)|Southeastern]] platforms within the paid area. Users of payment cards who have failed to touch in at the start of the journey, and other passengers without a correct ticket, may be liable to a £100 penalty fare or prosecution for fare evasion.

===Rolling stock===
[[File:DLR 106.jpg|thumb|right|DLR train at [[Poplar DLR station]]]]
{{Main|Docklands Light Railway rolling stock}}
The DLR is equipped with 149 high-floor [[Bi-directional vehicle|bi-directional]] single-[[Articulated vehicle#Trains and rail|articulated]] [[electric multiple unit]]s (EMUs). Each car has four double doors on each side, and two or three cars make up a train.<ref name="RWT-DLR-upgrade" />{{Failed verification|reason=For some of it, not all; upgrade report bad source for present rolling stock.|date=September 2022}} There are no cabs because normal operations are automated; a small driver's console is concealed behind a locked panel at each end, from which the PSA can drive the car.<ref>{{Cite news |url=http://londonist.com/2007/11/unmanned_train.php |title=Unmanned Train: DLR Respond |newspaper=The Londonist (blog) |date=2 November 2007 |access-date=19 March 2012 |url-status=live |archive-url=https://web.archive.org/web/20120222004250/http://londonist.com/2007/11/unmanned_train.php |archive-date=22 February 2012 }}</ref> 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. The operational top speed is {{convert|64|km/h|mph|abbr=on}}.

Despite having high floors and being automated, the cars are derived from a German [[light rail|light-rail]] design intended for street running. All cars look similar but there have been several different types, some still in service, others sold to other operators. Units were purchased from [[Bombardier Inc.|Bombardier]] in 2005 and delivered between 2007 and 2010.<ref>{{Cite press release |url=http://bombardier.com/en/corporate/media-centre/press-releases/details?docID=0901260d8000fc2d |title=Bombardier receives a $94&nbsp;million US order from Docklands Light Railway for automatic Light Rail cars to be used in London, UK |publisher=[[Bombardier Inc.|Bombardier]] |date=4 May 2005 |location=Montreal |access-date=14 July 2009 |url-status=live |archive-url=https://web.archive.org/web/20090821135659/http://bombardier.com/en/corporate/media-centre/press-releases/details?docID=0901260d8000fc2d |archive-date=21 August 2009 }}</ref>

====Future rolling stock====
In 2017, TfL opened bidding for new full-length, walk-through trains, subsequently awarded to [[Construcciones y Auxiliar de Ferrocarriles|CAF]] in 2019<ref>{{Cite press release |date=12 June 2019 |title=CAF wins driverless trains contract in London |url=https://www.caf.net/en/sala-prensa/nota-prensa-detalle.php?e=279 |publisher=CAF |location= Guipúzcoa}}</ref> and expected in service between 2024 and 2026,<ref name="improv">{{cite web  | url = https://tfl.gov.uk/modes/dlr/improving-the-dlr?intcmp=25179 | title = Improving the DLR | publisher = Transport for London | access-date = 12 February 2023}}</ref><ref name="mayornewtrain">{{cite news | url = https://www.railadvent.co.uk/2023/02/mayor-of-london-views-first-new-docklands-light-railway-train.html | work = Rail Advent | title = Mayor of London views first new Docklands Light Railway train | first1 = Roger | last1 = Smith | date = 9 February 2023 | access-date = 12 February 2023}}</ref> following delivery and testing on the network of the initial units from January 2023.<ref name="improv" /><ref name="mayornewtrain" /> An order was placed for 54 five-car trains: 33 to replace the oldest existing trains and the rest to increase service capacity.<ref name="improv" /> The design of the trains increases internal capacity by 10% which, combined with service improvements, will bring about a 65% increase in capacity from Stratford to Lewisham, and a doubling of capacity between Canning Town and Beckton or Woolwich Arsenal. The trains have charging points and air-conditioning.<ref>{{cite news |url=http://www.railtechnologymagazine.com/Rail-News/tfl-opens-bidding-for-43-new-dlr-trains |title=TfL opens bidding for 43 new DLR trains |work=Rail Technology Magazine |date=20 November 2017 |url-status=live |archive-url=https://web.archive.org/web/20171201035438/http://www.railtechnologymagazine.com/Rail-News/tfl-opens-bidding-for-43-new-dlr-trains |archive-date=1 December 2017 }}</ref>

===Depots===
The network has two depots, at [[Poplar DLR depot|Poplar]] and [[Beckton DLR depot|Beckton]]. Poplar was opened with the initial line in 1987. Due to the constrained site, a new, larger, depot at Beckton was opened in 1994 {{ndash}} and is now the main maintenance depot and primary control centre for the network.<ref name=":03">{{Cite book |last=Pearce |first=Alan |url=https://www.worldcat.org/oclc/137312784 |title=Docklands Light Railway : official handbook |date=2006 |publisher=Capital Transport |others=Brian Hardy, Colin Stannard, Capital Transport |isbn=1-85414-298-4 |edition=5th |location=Harrow |oclc=137312784}}</ref> Track maintenance, off-peak train stabling, as well as the Operating and Maintenance Centre (OMC for TfL Staff) and the Hilton, Ritz and Dorchester Buildings houses the KeolisAmey Docklands franchise staff and the secondary back-up control centre are based at Poplar.<ref name=":03" />

[[Buckingham Group]] was awarded a £35m contract in 2021 to upgrade the Beckton DLR depot to accommodate the new B23 rolling stock. Works include construction of a new carriage wash, extension and modification to existing track, and new sidings for the new trains. This was scheduled for completion in September 2023, but Buckingham went into administration the previous month (August 2023). TfL appointed [[Morgan Sindall]] to complete the work, alongside a £90m deal to build a new train shed and deliver further sidings.<ref name="Rogers-04Apr2024">{{cite news |last1=Rogers |first1=Dave |title=Buckingham collapse delays DLR job by months, TfL confirms |url=https://www.building.co.uk/news/buckingham-collapse-delays-dlr-job-by-months-tfl-confirms/5128735.article |access-date=4 April 2024 |work=Building |date=4 April 2024}}</ref>

=== Electrification ===
[[File:Docklands Light Railway - conductor rail 239091x.jpg|thumb|upright|Support arm and short length of conductor rail]]
Traction power is provided at 750 V DC via an unusual bottom contact third rail system.

===Signalling technology===
Originally, the DLR used [[Railway signalling|signalling]] based on a [[Railway signalling#Fixed block|fixed-block]] technology developed by [[General Electric Company|GEC-General Signal]] and [[General Railway Signal]]. This was replaced in 1994 with a [[Moving block signalling|moving-block]] TBTC (Transmission Based Train Control) system developed by [[Alcatel]], called [[SelTrac]].<ref name="DLRhandbookDLRhandbook-66">{{harvnb|Pearce|Hardy|Stannard|2000|p=66}}</ref> The SelTrac system was bought by [[Thales Group|Thales]] in 2007 and updates are provided by Thales Rail Signalling Solutions. The same technology is used by [[rapid transit]] systems including Vancouver's [[SkyTrain (Vancouver)|SkyTrain]], Toronto's [[Line 3 Scarborough|SRT]], the [[San Francisco Municipal Railway]] and Hong Kong's [[MTR]]. The [[SelTrac]] S40 system has also been adopted by the [[London Underground]] [[Jubilee line]] and [[Northern line]]. Transmissions occur via an inductive loop cable between each train's Vehicle On-Board Controller ([[VOBC]]) and the control centre (VCC, SMC) at Beckton. If this link is broken and communication is lost between the VOBC and VCC, SMC, the train stops until it is authorised to move again. If the whole system fails the train can run in restricted manual at {{convert|12|mph|km/h|abbr=on|order=flip}} for safety until the system is restored and communication is re-established. Emergency brakes can be applied if the train breaks the speed limit during manual control or overshoots a fixed stopping point, or if it leaves the station when the route has not been set.<ref name="RWT-DLR-upgrade" /> A secondary control centre is based at Poplar, the location of the original control centre, which can operate immediately should there be any issues with the primary at Beckton.<ref>{{cite web |url=https://content.tfl.gov.uk/dlr-franchise-agreement-redacted-version.pdf |archive-url=https://web.archive.org/web/20151120022959/http://content.tfl.gov.uk/dlr-franchise-agreement-redacted-version.pdf |archive-date=2015-11-20 |url-status=live |page=14 |title=Franchise Agreement: Docklands Light Railway Limited and Keolis Amey Docklands Limited relating to the Docklands Light Railway |date=17 July 2014 |publisher=[[Transport for London]]}}</ref>
