The North London Line is a railway line in London, England, owned and maintained by Network Rail. It is part of the London Overground network and is an important freight route. At its fullest extent it described roughly a semicircle through the inner northern suburbs from Richmond in the west to North Woolwich in the east, avoiding central London. In 2006 the section from Stratford to North Woolwich was cut off for conversion to a Docklands Light Railway line.

Although much of it was part of the North London Railway, the route is the result of a series of amalgamations, closures and re-openings of connecting sections which were opened over 25 years from 1846:

  • The easternmost section opened as the Eastern Counties and Thames Junction Railway in 1846/7 between Stratford and North Woolwich. When the Royal Victoria Dock was constructed later a swing-bridge was put south of Canning Town on the original route and the main line was rerouted in 1850 via Custom House and the Connaught Tunnel. The original route remained as the Silvertown Tramway, a local freight loop off the new main line.
  • The main central section opened from 1850 to 1852 as the East & West India Docks & Birmingham Junction Railway (renamed the North London Railway (NLR) in 1853). This linked the London and North Western Railway main line near Primrose Hill to the docks at Poplar via Bow.
  • The last link in the east was opened between the NLR near Victoria Park and Stratford in 1854.
  • To obviate NLR trains running on the busy Euston main line, the Hampstead Junction Railway was opened from the NLR at Camden Road to Willesden via Hampstead Heath in 1860.

Developments[edit]

The LNWR electrified the lines fron Broad Street to both Richmond and Kew Bridge in 1916 on the 4th rail DC system.Passenger service to Kew Bridge ended in 1940.

NLR Poplar branch passenger service ceased in 1944. Freight traffic continued on the branch until the docks on the Isle of Dogs closed during the 1960s and 1980s. The trackbed of the southern part of the branch, from Poplar to Bow, was used for the Docklands Light Railway branch to Stratford.

In 1979 the North Woolwich to Stratford service was extended to Camden Road as the "CrossTown LinkLine" service using the same Cravens-built diesel multiple unit trains. There were no intermediate stations until in 1980 Hackney Wick opened near the site of the former Victoria Park station, and Hackney Central re-opened; Homerton re-opened in 1985 (both those stations had closed in 1944). Platforms were built at West Ham for interchange with the adjacent Underground station.

After Broad Street closed in 1986 NLL services ran between Richmond and North Woolwich,. and the Tottenham Hale–Stratford link and the station at Lea Bridge ceased to be used by regular passenger trains >>>>>>>>>>>> The NLL now has a mixed third-rail and overhead electrical power supply. The line between Dalston and North Woolwich was electrified on the third-rail system and Broad Street services were diverted to North Woolwich using former Southern Region 2-EPB types built in the 1950s. The two-coach trains soon proved too small and were replaced by Class 313 electric multiple units. The new service was branded by British Rail as the North London Link, and some signs using this name still exist. >>>>>>>>>>>>>

In December 2006, the line between Stratford and North Woolwich was permanently closed to make a way for a future Docklands Light Railway (DLR) extension from Canning Town to Stratford International (Opening December 13, 2009). The section south of Canning Town is largely duplicated by the DLR King George V branch and the stretch of track from Canning Town to Stratford follows the Jubilee Line..

The whole of the remaining Silverlink Metro became part of Transport for London's (TfL) London Overground in 2007.

XXXXXXXXXXXXXXXX To resignal the NLL and to extend thirty platforms to allow four-car trains to run, the line is to be closed between Gospel Oak and Stratford from February 2010 until 1 June 2010. Engineering work will continue further until May 2011, with services reduced and Sunday services suspended.[1]

Former services[edit]

Besides the primary Broad Street to Richmond service, Broad Street was linked to Harrow & Wealdstone and Watford Junction on the West Coast Main Line usually via South Hampstead and Camden Road, calling at Primrose Hill, but some ran via Hampstead Heath and joined the Watford line at Willesden Junction. By the time Broad Street closed the Watford services were rush-hour only, and they were then diverted to Liverpool Street by the new single-track Graham Road Curve in Hackney. However trains were often cancelled and some timings to and fron Liverpool Street after the start oid not fit the working day and so patronage was very low and after a few years they were withdrawn.

In 2000 Anglia Railways started a service called London Crosslink between Basingstoke and Ipswich which ran over part of the North London Line. It ran up to five times a day at roughly two-hourly intervals calling only at principal stations such as Staines, Feltham and Brentford. On the NLL the trains called only at Stratford, Highbury & Islington, sometimes Camden Road, West Hampstead and Willesden Junction. The service was withdrawn in 2002, despite the limited stop timetabling the trains often crept, trappped by the undependable NLL service.

Between Camden Road and the junctions for Broad Street the NLL had four tracks, the south pair for the electric passenger services and the northern pair for steam hauled trains. <><><> The AC electrification of the eastern part of the North London Line uses the previously unelectrified northern pair of tracks, which were also partially singled at the same time. Between Canonbury and Highbury & Islington there is a line which links to the East Coast Main Line at Finsbury Park. This used to carry passenger trains to / from various North London stations (such as Edgware, Alexandra Palace, High Barnet, Welwyn Garden City and others) over part of the North London Line to Broad Street Station, however since the opening of the Great Northern Electrics suburban electrification which in the 1970s saw trains being diverted into Moorgate and London King's Cross stations; this link has only been used for freight trains. It too was singled concurrent with the AC electrification of the eastern part of the North London Line.

Route[edit]

Geographical map of the North London Line

Track[edit]

Most of the line runs in a curve across north London. Only Richmond and Kew Gardens stations at the western end are south of the River Thames. The river crossing is made by Kew Railway Bridge on tracks which are shared with the London Underground District Line. The location of the eastern extremity has varied over the years. Between 1944 and 1986 it was at Broad Street station, then it switched to North Woolwich. It was cut back to Stratford. A tunnel, the Hampstead Heath tunnel, runs under Hampstead between Finchley Road & Frognal and Hampstead Heath. The line is double track throughout with a mix of triple and quadruple track between Camden Road and Dalston Kingsland. The former North Woolwich branch included a section of single track between Custom House and North Woolwich stations, and the Broad Street branch was at one time formed of quadruple track.

Electric supply[edit]

The line is electrified using the third rail system from Richmond to Acton Central and Camden Road to Dalston Kingsland (southern pair of lines only). Overhead lines are used from Acton Central to Camden Road, Camden Road to Dalston Kingsland (freight lines only) and Dalston Kingsland to Channelsea Junctions (link to Temple Mills, Stratford High Level and Liverpool Street). The line to Broad Street used third rail supply and when the through service to North Woolwich started in 1985 trains used the third rail throughout. When the trains were replaced a few years later by dual-system Class 313 trains it became possible to use the overhead electrification system which had been added to parts of the line for the benefit of freight trains. There had been some unexpected difficulties with earth currents from the third rail system which this overcame. This usage was steadily extended and the trains now make a number of changes between electrification systems during their short journey. These are at Dalston Kingsland, Camden Road and Acton Central.

The line is now electrified thus Third rail Richmond to Acton Central and Camden Road to Dalston Kingsland. It is electrified at overhead 25kv between Acton Central and Camden Road and Dalston Kingsland to Stratford. This will change during the year 2010. When the only section of line to third rail will be Richmond to Acton Central. The rest of the line between Acton Central and Stratford will be at overhead 25kv.

Connections[edit]

The line crosses or comes into contact with a very large number of railway lines, especially lines radiating from central London. This does provide opportunities to move between separate sectors of suburban London without having to enter the central zone.

Interchanges shown on the tube map[edit]

Other interchanges[edit]

former interchanges[edit]

  • at North Woolwich passengers could cross the Thames via the Woolwich foot tunnel or the free ferry to Woolwich Arsenal station for connections on the North Kent line to Medway Towns, Gravesend, Dartford, Sidcup, Abbey Wood, Blackheath, Lewisham, Greenwich and Central London

Current operations[edit]

Rolling stock[edit]

Old and new: a class 313 train and its replacement, the 378, at Richmond

The London Overground passenger service uses Class 313 dual voltage electric trains compatible with both 750v DC third-rail and 25kV AC overhead power sources. Each train is made up of three coaches each and are part of a fleet of 23 units shared with other London Overground routes. They are in the process of being replaced by 24 three car Class 378 trains in 2009, which will be extended to four cars in 2010.[2]

Service levels[edit]

Despite published performance figures[3] the North London Line is regarded by frequent travellers as offering a poor service,[4] with extremely congested trains and an unreliable service[5] with some trains cancelled shortly before they are due to arrive. A 2006 London Assembly report described the current service as "shabby, unreliable, unsafe and overcrowded", proposing the transfer of the service to Transport for London (TfL) as a potential solution to improve the quality of the service [6] due to upgrade plans [7] which coincide with the extension of the East London line.

A report on the future of the line can be found on the London Assembly website[8].

Development[edit]

Map of the projected London Overground network, with the NLL connected to other lines

Confirmed[edit]

  • By 2011, according to TfL, all lines will be provided with a 'turn up and go' service, which means a minimum of 4 trains per hour in both directions.[10]
  • Planned service patterns[11] are:
  • 4 tph Stratford - Camden Road - Gospel Oak - Willesden Junction - Richmond (as current service)
  • 2 tph Stratford - Camden Road - Gospel Oak - Willesden Junction - Clapham Junction
  • 2 tph Stratford - Camden Road

Proposed[edit]

  • The route between Custom House and North Woolwich is proposed to be used by the Crossrail project as part of the Abbey Wood branch. There were plans for this section to be used temporarily by the Royal Docks Heritage Railway but the present status of this project is unclear.
  • Maiden Lane station may be reopened by Camden Council[12] however the Office of Rail Regulation has not included this in the current plans[13].

Closed stations[edit]

Silverlink Metro 313117 at North Woolwich on 9 December 2006, the final day of service at that station

Closed stations apart from those on the closed sections of the line are:

City Extension[edit]

On 1 November 1865 the NLR opened its City Extension mostly on a viaduct from a triangular junction at Dalston to Broad Street in the City with these stations:

The extension closed on 30 June 1986, but although the track was lifted the viaduct remains in place and is partially used for the East London Line development.

The extended East London Line will be operated by London Overground, the operators of passenger services on the North London Line, with services eventually running as far as Highbury & Islington in the north for interchange with the Victoria line.

North Woolwich section[edit]

On 10 December 2006 the line between Stratford and North Woolwich was closed to allow building between Stratford and Canning Town of a Docklands Light Railway line to Stratford International. Part of the south end of closed section is to be used for Crossrail.[15]

NLL stations closed were:

DLR and Jubilee line services are not affected at the first three of those stations.

The DLR line to Stratford International will use the former NLL low level platforms at Stratford. NLL trains now terminate at new platforms on the north side of the high level station.
