The original [[Metropolitan District Railway]] (as it was then called) opened in December 1868 from South Kensington to {{lus|Westminster}} as part of a plan for a below-ground "inner circle" connecting London's main line termini. At first, services were operated using wooden carriages hauled by steam locomotives. Electrification was financed by the American [[Charles Yerkes]], and electric services began in 1905. The railway was absorbed by the [[London Passenger Transport Board]] in 1933. In the first half of the 1930s, the Piccadilly line took over the Uxbridge and Hounslow branches, although a peak-hour District line service ran on the Hounslow branch until 1964. Kensington (Olympia) has been served by the District line since 1946, and a short branch to {{rws|South Acton|England}} closed in 1959. The trains carried [[Train guard|guards]] until [[one-person operation]] was introduced in 1985.

The signalling system is being upgraded (as part of the [[Four Lines Modernisation]] project) as of September 2019 and the previous [[D Stock]] trains were fully replaced by seven-car [[London Underground S7 and S8 Stock|S Stock]] trains in April 2017.

== History ==
{{Main|History of the District line}}

=== District Railway ===
{{Main|District Railway}}
The Metropolitan District Railway (commonly known as the District Railway) was formed to build and operate part of an underground 'inner circle' connecting London's railway termini. The first line opened in December 1868, with services from South Kensington to Westminster; these were operated by the [[Metropolitan Railway]] using wooden carriages hauled by [[steam locomotive]]s. By 1871, when the District began operating its own trains, the railway had extended to West Brompton and a terminus at [[Mansion House tube station|Mansion House]].{{sfn|Green|1987|pp=8–10}} A curve from [[Earl's Court tube station|Earl's Court]] onto the [[West London Railway]] was used by the [[London & North Western Railway]] (L&NWR) for a service to {{rws|Broad Street|England}} and the [[Great Western Railway]] for a service to Moorgate via Paddington.{{sfn|Horne|2006|p=15}} Between 1 March 1883 and 30 September 1885, the District Railway ran trains between Mansion House and [[Windsor & Eton Central railway station|Windsor]], via Paddington. Stations after Ealing Broadway (the current terminus) were West Ealing, Hanwell, Southall, Hayes & Harlington, West Drayton, Langley, Slough, and Windsor. The service was discontinued because it was uneconomic.{{sfn|Rose|2007}}{{sfn|Day|Reed|2010|p=26}}

Hammersmith was reached from Earl's Court, services were extended to Richmond over the tracks of the [[London and South Western Railway]] (L&SWR), and branches reached Ealing Broadway, Hounslow and Wimbledon. As part of the project that completed the [[Circle line (London Underground)|Circle line]] in October 1884, the District began to serve [[Whitechapel station|Whitechapel]].{{sfn|Green|1987|p=12}} Services began running to Upminster in 1902, after a link to the [[London, Tilbury & Southend Railway]] (LT&SR) had been built.{{sfn|Green|1987|p=28}}

[[File:Experimental Train.jpg|thumb|The jointly owned experimental passenger train that ran for six months in 1900|alt=A three-quarter black-and-white photograph of a train standing at a station, showing the end carriage with windows at the end.]]

At the start of the 20th century, the District was seeing increased competition from the new electric underground tube lines and trams, and the use of steam locomotives underground led to unpopular smoke-filled stations and carriages.{{sfn|Green|1987|p=28}} The American [[Charles Yerkes]], who was later to form the [[Underground Electric Railways of London]], financed the necessary electrification of the railway, and the first electric services ran from Ealing to South Harrow in 1903.{{sfn|Green|1987|pp=24–27}} Electric multiple-units were introduced on other services in 1905, and East Ham became the eastern terminus. Electric locomotives were used on the L&NWR services from Mansion House to Earl's Court, and in later years exchanged for a steam locomotive on LT&SR services from Southend to Ealing Broadway at Barking.{{sfn|Green|1987|p=28}}

Hounslow and Uxbridge were served by 2 or 3-car shuttles from Mill Hill Park (now Acton Town); some trains also served South Acton and central London in the peaks.{{sfn|Horne|2006|p=44}} Services were extended again to Barking in 1908 and Upminster in 1932.{{sfn|Horne|2006|pp=45, 61}} In 1932 [[Piccadilly line]] trains were extended from Hammersmith to South Harrow, taking over the District service from Acton Town to South Harrow, although the District continued to provide a shuttle from South Harrow to Uxbridge.{{sfn|Horne|2006|p=58}} In 1933, Piccadilly line trains reached Hounslow West, the District continuing to run services with an off-peak shuttle from South Acton to Hounslow.{{sfn|Horne|2006|p=60}}

=== London Transport ===
On 1 July 1933, the District Railway amalgamated with other Underground railways, tramway companies and bus operators to form the [[London Passenger Transport Board]], and from 23 October 1933 Piccadilly line trains ran through to Uxbridge and the District line shuttle was withdrawn.{{sfn|Horne|2006|p=65}} Most of the trailer cars on the District line were the 1904–1905 [[London Underground B Stock|B Stock]] type with wooden bodies, but motor cars were less than fifteen years old. The 1935–1940 [[New Works Programme]] saw the [[London Underground Q Stock|Q Stock]] formed from these motor cars, upgraded with electro-pneumatic brakes and guard controlled air-operated doors, and the trailers replaced with new vehicles.{{sfn|Bruce|1983|p=36, 83, 96}} The off-peak District line services on the Hounslow branch were withdrawn on 29 April 1935 and South Acton served by a shuttle to Acton Town.{{sfn|Horne|2006|p=60}}

[[File:R Stock painted and unpainted at South Kensington.jpg|thumb|left|An R Stock train composed of a mixture of unpainted aluminium and (white) painted steel cars]]

The [[London, Midland and Scottish Railway]] (LMS) had taken over the L&NWR railway's service from Earl's Court and by the [[Second World War]] this had been cut back to an electric Earl's Court to Willesden Junction shuttle.{{sfn|Horne|2006|p=60}} Following bombing of the West London Line in 1940, the LMS and the Metropolitan line services over the [[West London Line]] were both suspended. This left the [[Olympia (London)|Olympia exhibition centre]] without a railway service, so after the war the Kensington Addison Road station was renamed [[Kensington (Olympia)]] and served by a District line shuttle from Earl's Court.{{sfn|Horne|2006|p=73}} [[London Underground R Stock|R Stock]], composed of new cars and the Q Stock trailers that had been built in 1938, replaced the trains with hand-operated sliding doors that remained.{{sfn|Horne|2006|pp=74–75}} The new trains were built between 1949 and 1959,{{sfn|Horne|2006|p=75}} and after 1952 trains were constructed from aluminium, saving weight. One train was left unpainted as an experiment and considered a success, so between 1963 and 1968 trains were left unpainted or painted white or grey to match.{{sfn|Bruce|1983|pp=100–101}} The transfer of [[London Underground O and P Stock|CO/CP Stock]] from the Metropolitan line in the early 1960s allowed some of the Q stock to be scrapped.{{sfn|Bruce|1983|p=97}} The slow tracks on the former LT&SR line to Upminster were shared with steam locomotive hauled goods and passenger services, until 1961 when the District took over exclusive use of the DC electrified lines.{{sfn|Horne|2006|pp=80–82}}

The South Acton shuttle was withdrawn on 28 February 1959, followed by the peak hour District line through service to Hounslow on 9 October 1964.{{sfn|Horne|2006|p=88}} The whole District line service could not run through Aldgate East as this station was also served by Hammersmith & City trains, so some trains terminated at a bay platform at Mansion House, leaving the line east to Tower Hill overcrowded. Tower Hill station was also cramped, so the station was rebuilt with three platforms on a new site. This opened in 1967 and a year later trains reversed at the new station.{{sfn|Horne|2006|pp=88–89}}

Services were operated with 6 cars off-peak and 8 cars during peak hours until 1971, when trains were reformed as fixed 7-car trains, and some 6-car trains for the Edgware Road branch.{{sfn|Bruce|1983|pp=103, 118}} The CO/CP and R Stock were replaced in the late 1970s by new trains with unpainted aluminium bodies.<ref name="RSI">{{cite web|title=Rolling Stock Information Sheets |url=http://www.tfl.gov.uk/assets/downloads/foi/Rolling_stock_Data_Sheet_2nd_Edition.pdf |access-date=26 November 2012 |publisher=London Underground |url-status=dead |archive-url=https://web.archive.org/web/20131004231025/http://www.tfl.gov.uk/assets/downloads/foi/Rolling_stock_Data_Sheet_2nd_Edition.pdf |archive-date=4 October 2013}}</ref> A shorter train was needed on the Edgware Road branch due to the platform lengths so more of the [[London Underground C69 and C77 Stock|C stock]] units, then already in use on the Circle and Hammersmith and City lines, were built.{{sfn|Bruce|1983|p=117}} The rest of the District line could use longer trains and new [[D Stock]] trains were introduced between 1979 and 1983.<ref name="RSI" /> [[Driver-only operation]] of the trains was proposed in 1972, but due to conflict with the trade unions was not introduced on the District line until 1985.<ref>{{cite book|last1=Croome|first1=Desmond F.|last2=Jackson|first2=Alan Arthur|title=Rails Through the Clay: A History of London's Tube Railways|year=1993|publisher=Capital Transport|page=468|isbn=978-1-85414-151-4}}</ref> In 2003, the infrastructure of the District line was partly privatised in a [[public–private partnership]], managed by the [[Metronet (British infrastructure company)|Metronet]] consortium.

After about {{convert|2/3|mi}}, the line meets the Piccadilly line Uxbridge branch at Hanger Lane junction, and the tracks are then shared through [[Ealing Common station]] until [[Acton Town station]], where the Piccadilly line Heathrow branch joins. From Acton Town to Barons Court, the line has four tracks, paired by use: the District line uses the outer pair and the non-stopping Piccadilly line trains use the inner pair.<ref name="map">{{cite web |url= http://cartometro.com/cartes/metro-london/ |title=Detailed London Transport Map |access-date=1 December 2012|work=cartometro.com}}</ref> At [[Richmond station (London)|Richmond station]], the [[Mildmay line]] and District line platforms are north of the [[Waterloo to Reading line]] through platforms. The two tracks which cross the Thames at [[Kew Railway Bridge]] are shared with the Mildmay line trains until Gunnersbury junction, after which the District line tracks join the four-track District and Piccadilly lines just before [[Turnham Green station]].<ref name="map" />

On the main line, there are [[cross-platform interchange]]s at Acton Town, Hammersmith and Barons Court stations, after which the Piccadilly line tracks descend into tunnels, while the District line becomes two tracks through West Kensington station. Before the line enters Earl's Court station, the short Kensington (Olympia) branch joins at a flat junction and the Wimbledon branch at a grade-separated junction.<ref name="map" /> On the Wimbledon branch, the District line at [[Wimbledon station]] is west of the [[South West Main Line]] platforms, then the two-track line has a junction at [[East Putney station]] with the [[Hounslow Loop Line]], before passing over the River Thames on [[Fulham Railway Bridge]]; the line continues by passing under the West London Railway and coming alongside it at [[West Brompton station]] before the junction with the main line and the four-platform Earl's Court station.<ref name="map" />

[[File:Earl's Court District Line platforms.jpg|thumb|left|Overhead view of the District line platforms at Earl's Court, 2005]]

East of Earl's Court there is a grade-separated junction off the main line to the Edgware Road branch. This follows the Circle line after [[High Street Kensington station]] where there are also two bay platforms for the District line. After [[Paddington tube station (Bakerloo, Circle and District lines)|Paddington station]] this branch joins the [[Hammersmith & City line]] at Praed Street junction, before terminating at the four-platform [[Edgware Road tube station (Circle, District and Hammersmith & City lines)|Edgware Road]].<ref name="map" /> The main line joins the Circle line at Gloucester Road and the line and stations are in cut-and-cover tunnels, meeting the Thames at [[Westminster station]], after which the railway is in the [[Victoria Embankment]] on the north bank of the river. At [[Tower Hill tube station|Tower Hill]] station, there is a bay platform.<ref name="map" />

After Tower Hill, the Circle line diverges, the District line joining the Hammersmith & City line just before [[Aldgate East station]]. The line passes over the Windrush line at Whitechapel station before continuing on the {{convert|2|mi|adj=on}} [[Whitechapel & Bow Railway]] to Bow Road, where the line surfaces, and Bromley-by-Bow, where the line runs alongside the [[London, Tilbury and Southend line]] from [[Fenchurch Street station]]. There is an interchange with this line at the next station, West Ham, as well as with the [[Jubilee line]] and the [[Docklands Light Railway]]. There is a bay platform at the next station, Plaistow, and the Hammersmith & City line terminates at Barking station.<ref name="map" /> The District line follows the London, Tilbury and Southend Railway for another eight stations, before terminating at [[Upminster station]].<ref name="map" />

The line mainly runs in cut and cover tunnels between [[West Kensington]] and [[Bow Road]], including the Edgware Road branch. However, due to the nature of sub-surface lines, the cutting is occasionally left open both at and between stations for ventilation. West of Earls Court, the line is entirely surface level, with the exception of the Hammersmith and Fulham Broadway stations, which are in cuttings built over by recent developments. There is also a small section of tunnel between Southfields and East Putney.

Now served by the Piccadilly line, the Hounslow branch opened to the now closed [[Hounslow Town tube station|Hounslow Town]] on 1 May 1883 and was extended on a separate route to [[Hounslow West tube station|Hounslow West]] on 21 July 1884. The District line served the present Piccadilly line stations between Acton Town and Hounslow West as well as the former station of [[Osterley & Spring Grove tube station|Osterley & Spring Grove]] (closed 1934) until District line 
services were withdrawn on 9 October 1964. From 13 June 1905 until 28 February 1959, the District line ran a one-stop shuttle between Acton Town and [[South Acton railway station (England)|South Acton]].{{sfn|Rose|2007}}

Also now served by the Piccadilly line, the [[South Harrow tube station|South Harrow]] branch opened from north of Ealing Common on 28 June 1903 and extended over Metropolitan Railway tracks to [[Uxbridge tube station|Uxbridge]] on 1 March 1910. The District line served the present Piccadilly line stations between [[North Ealing]] and South Harrow until 4 July 1932 and the stations between [[Rayners Lane tube station|Rayners Lane]] and Uxbridge until 25 October 1933. The District Railway also served the now closed [[Park Royal & Twyford Abbey tube station|Park Royal & Twyford Abbey]] until its replacement by [[Park Royal tube station|Park Royal]] on 6 July 1931.{{sfn|Rose|2007}}

Between 1 March 1883 and 30 September 1885, the District Railway provided a service to Windsor, serving: West Ealing, Hanwell, Southall, Hayes & Harlington, West Drayton, Langley, Slough, and Windsor.{{sfn|Rose|2007}}{{sfn|Day|Reed|2010|p=26}}

From 1910 to 1939, the District line's eastbound service ran as far as [[Southend-on-Sea]] and [[Shoeburyness]].{{sfn|Day|Reed|2010|p=66}}

Currently part of the [[East London line]], the District Railway branched away from the main line west of Whitechapel and served stations between Shadwell and New Cross from 1 October 1884 until 31 July 1905.{{sfn|Rose|2007}}

Between Whitechapel and Aldgate East, the District line served [[St Mary's (Whitechapel Road) tube station|St. Mary's (Whitechapel Road)]] from 1 October 1884 to 30 April 1938, closing when Aldgate East station moved.{{sfn|Rose|2007}}{{sfn|Horne|2006|pp=25, 68}}

From 25 September 1882 until its closure on 12 October 1884, [[Tower of London tube station|Tower of London]] station was served by the District Railway.{{sfn|Rose|2007}}

===Abandoned plans===
In 1911, the [[Underground Electric Railways Company of London]] agreed to finance the construction of the [[Wimbledon and Sutton Railway]] and eight new stations for the [[Sutton Underground Line Proposal|extension of District Railway services to Sutton]]. Construction of the line was delayed by [[World War I]] and, as part of a deal with the [[Southern Railway (UK)|Southern Railway]] (SR) to agree to the extension of the [[City and South London Railway]] to [[Morden tube station|Morden]], construction of the line was taken over by the SR.<ref name=National_Archive_1>[http://www.nationalarchives.gov.uk/catalogue/displaycataloguedetails.asp?CATID=8444027&CATLN=6&accessmethod=5 National Archives - piece: RAIL 647/70, Heads of Agreement, 25 July 1923]</ref><ref name=National_Archive_2>[http://www.nationalarchives.gov.uk/catalogue/displaycataloguedetails.asp?CATID=8444028&CATLN=6&accessmethod=5 National Archives - piece: RAIL 647/71, Heads of Agreement, 25 July 1923]</ref>

In the ''[[Sherlock (TV series)|Sherlock]]'' episode "[[The Empty Hearse]]", a fictional unopened terminus station called Sumatra Road (situated underneath the [[Houses of Parliament]] as a disused branch line from Westminster Station) was created for the episode's story of a terrorism plot. The station was actually filmed at [[Aldwych tube station|Aldwych]] with ex-Northern line [[London Underground 1972 Stock|1972 stock]] which caused continuity errors as deep-level trains and tunnels were used when the District line is sub-surface.<ref>{{cite web | url=https://www.buzzfeed.com/jimwaterson/the-london-underground-lines-in-sherlock-are-all-wrong | title=The London Underground Lines In "Sherlock" Are All Wrong | work=Buzzfeed | access-date=3 January 2014 | author=Waterson, Jim| date=2 January 2014 }}</ref>
