Thameslink Programme
Encyclopedia
The Thameslink Programme, originally Thameslink 2000, is a £6 billion project in south-east England to upgrade and expand the Thameslink rail network
Thameslink
Thameslink is a fifty-station main-line route in the British railway system running north to south through London from Bedford to Brighton, serving both London Gatwick Airport and London Luton Airport. It opened as a through service in 1988 and by 1998 was severely overcrowded, carrying more than...

 to provide new and longer trains between a wider range of stations to the north and to the south of London without requiring passengers to change trains in London. Work includes platform lengthening, station remodelling, new railway infrastructure, and additional rolling stock. The project was originally proposed in 1991 following the successful introduction of the initial Thameslink service in 1990. After many delays, planning permission was granted in 2006 and funding was approved in October 2007. Work started in earnest in 2009 and is expected to be complete in 2018.

British Rail plans

British Rail proposed to expand and upgrade the original network in the early 1990s with plans to increase the number of stations served from 50 to 169 and increase the passenger capacity of the network by allowing 12-carriage trains and allowing more trains per hour. In 1993 responsibility for the project, which was intended to be completed by 2000 was transferred to Railtrack

. The Government and LCR did however reach agreement in June 1998 allowing the construction of High Speed 1 and also the associated works required for the Thameslink programme to proceed.

During this period Railtrack carried out an extensive public consultation exercise, which resulted in the revision of their original proposals and subsequently they submitted a Supplementary Order on 29 September 1999.

 decided to call for a public inquiry, which commenced in June 2000 and was brought to a close in May 2001. The Inspector spent several months compiling a report on the proposals submitted by Railtrack and the feedback provided by various parties for and against the project before submitting the report to the Government. On 30 July 2002, the Office of the Deputy Prime Minister (ODPM, now known as the Department for Communities and Local Government

The second public inquiry took place between September to December 2005 and the Inspector completed the report in February 2006 which it was submitted to the DfT for consideration. In October 2006 the DfT subsequently published the second report which declared that the Inspector was satisfied that the deficiencies from the previous Thameslink 2000 proposals had been resolved satisfactorily recommending that the project be approved.

, formally announced that the Government was fully committed to funding the Thameslink Programme. Since the planning permission and legal powers associated with the project had already been granted, the project was now clear to proceed.

With the downturn in the economy there was some doubt that phase 2 of the project would be completed in its entirety, but on 25 November 2010 the Secretary of State for Transport (Philip Hammond) confirmed that no cutbacks would be made. However the project completion would be delayed until 2018 as the schedule was already difficult to achieve and because cost savings could be made if the level of concurrent activity was reduced.

Construction

Construction is divided into three stages, each with 'Key outputs'. Key Output 0 was to make service changes to allow other work to proceed. Key Output 1 is for work that must be completed prior to the 2012 Olympics

. Work for Key Output 2 will start after the London Olympics with a planned completion of 2018.

Key Output 0 (Completed March 2009)

The first stage, completed on 22 March 2009, was to introduce service changes to allow the major work to take place. The terminal platforms at Blackfriars were closed as was the Farringdon to Moorgate branch line. A 15tph peak hour service was introduced on the core section between St. Pancras and Blackfriars. A new footbridge was constructed at Farringdon to improve interchange with London Underground's Circle line. A temporary entrance (now removed) was created at Blackfriars station.

This involved signalling works and alterations to the tracks and overhead line equipment between Farringdon and City Thameslink to allow the merged services to operate. Trains from the south which previously terminated at Blackfriars now terminate at Kentish Town

 Electrostars have been procured in order to meet the additional rolling stock requirements.

Key Output 1 (by mid 2012)

All aspects of Key Output stage 1 are planned to be complete by mid-2012, in time for the London Olympics. A major objective of this phase is to enable 12-carriage trains to run on the Bedford-Brighton route. Work affecting this should be complete in time for the December 2011 timetable change and will result in 10,000 extra peak-period seats from then. By then 23 stations between Bedford and Brighton should have been extended to accommodate the longer trains; in addition, Farringdon and Blackfriars stations would have been rebuilt to take 12-car trains and allow for increased passenger flows. Works at Farringdon also allow for the east-west Crossrail

It is planned that the fly-down at Tanners Hill will be widened and become double-track during this period.

Key Output 2 (2013-2018)

From 2013 there will be major track, signalling and station remodelling works at London Bridge station as part of the Masterplan project (some works within the station building may start during Key Output 1). A grade-separated junction

 (track level, in this case including both plain rail and junctions) and overhead line equipment will be laid out in the new Canal Tunnels just north of St Pancras between the Thameslink route and the East Coast Main Line, thereby opening up the Thameslink network to new destinations north of London.

Once the project is completed, the Thameslink network will be able to handle a nominal peak-period frequency of 24 trains per hour (tph) (equivalent to one train every 150 seconds) through the central core between St Pancras and Blackfriars from 2018, providing an extra 14,500 peak-period seats compared to the current level of service.

As part of the project, a purpose-built fleet of 1,100 new passenger vehicles (equivalent to 275 four-car trains) would operate across the network. The procurement process started on 9 April 2008. To meet the power requirements of this new fleet, electricity-supply enhancement works will be carried out during most of the entire project, creating 11 new feeder stations/sub-stations, upgrading a further 21 and converting 9 from track sectioning/paralleling equipment; in addition, new track sectioning/paralleling equipment will be installed in 9 locations and upgraded in a further 4.

City Thameslink station

City Thameslink station has been upgraded to enable 12-car trains to call. The platforms themselves were already long enough, but it was necessary to replace and enhance the CIS (Customer Information Screens) so that information is displayed in a standard format across the central section. New lighting and ticket gates have also been installed. The work was completed in October 2010.

London Bridge station

London Bridge station will undergo a major transformation to accommodate 12-car trains and achieve many other benefits. Three terminus platforms will be closed and three new through platforms created, to allow additional services to continue into Cannon Street or Charing Cross, or to Thameslink stations north of the Thames. A new station concourse will be built to improve circulation, and the adjacent bus station expanded. New retail facilities will be built into the existing western arcade, which will be re-opened and extended to link the Underground station and Joiner Street.

As shown in the revised timetable from 13 December 2008, capacity constraints mean that through London Bridge there are no northbound Thameslink trains in the morning peak between 07:24 and 09:09, and no southbound Thameslink trains in the evening peak between 16:43 and 18:27. During these times, Brighton line Thameslink trains go via Herne Hill

Work will start in 2013 and is expected to be completed by 2018.
During these works it is expected that more, or all, Thameslink trains will be diverted via Herne Hill and will not call at London Bridge.

'Fit-out' works began in summer 2006 (following the decision by the DfT to provide a further £60-65 million for the High Speed 1 project).

Other Stations

Work has been or is being carried out at a number of stations north of the Thames to extend the platforms to accommodate 12-car trains. These vary from quite major works such as at Luton, where new bridges had to be installed, and West Hampstead, where a new station footbridge has been built, to relatively straightforward platform extensions.

 building to the south.

The new, southern pair of tracks will be used by trains to and from Charing Cross. Thameslink trains will have a dedicated route to Blackfriars on the northern pair of tracks, which is key to providing the nominal peak-hour frequency of 24tph on the core route.

This controversial work has required the demolition of 20 grade 2 listed buildings and many other buildings within Borough Market, which is a Borough High Street Conservation Area, and the original Thameslink programme was rejected at public inquiry partly on the grounds that suitable arrangements were not included to replace the buildings to be demolished within the market. A revised proposal involving remedial work to the market was accepted at a second public inquiry. By January 2009 businesses in the path of the new viaduct were closing down or relocating in preparation for demolition work, and the first section of the new viaduct was installed over the weekend of 10 October 2010. These works had been brought forward to fit in with other, non-railway, developments in the Borough High Street area; the viaduct will not see actual use until 2018 as part of Key Output 2.

Bermondsey dive-under

With the completion of Borough Market Viaduct to the west of London Bridge, Thameslink trains will need to run on a pair of tracks to the north of the pair used by trains to Charing Cross. However, Thameslink trains currently arrive on the southern pair of tracks. The lines will therefore be rebuilt to the east of London Bridge so that Thameslink trains from the Brighton Main Line

To improve capacity on the line between London Bridge and Lewisham, a new stretch of single track will be built alongside the existing bi-directional single track between Tanners Hill Junction (near St John's Station) and Lewisham Vale Junction. Before the new track is laid, St John’s Vale Road Bridge will be partially demolished and reconstructed with a concrete pier, as well as a new south span over the new track; and the existing embankment along the fly-down will also be widened. As the existing footbridge will be rebuilt, a temporary footbridge will be provided for the duration of the works.

. The crossover currently located within City Thameslink station for the purpose of allowing trains from Smithfield sidings to enter platform 2 will be removed once Blackfriars station is rebuilt.

Between City Thameslink and Blackfriars a large electrical substation has been built at Ludgate Chambers. This 20MW substation is the largest on the 750 V DC third-rail network.

Provisional timetable

In 2011 a provisional timetable was released for Thameslink services in the London and South East Route Utilisation Strategy. It confirms that the Sutton loop services will be curtailed at Blackfriars.

Rolling stock

As of 2008, the existing Thameslink fleet consisted of 74 dual-voltage Class 319s and two Class 317s. While the Thameslink Rolling Stock Project (TRSP) will provide a brand-new fleet, the timescales involved are such that interim solutions are required. On 4 April 2007, the DfT authorised the transfer to Thameslink from Southern

, which was not exploiting their dual-voltage capacity, of 12 Class 319s, so that First Capital Connect now have all 86 Class 319 units. Once project funding was guaranteed, 23 Class 377/5s were also cascaded from Southern to meet the capacity requirements of Key Output 0.

The December 2011 timetable (i.e. after Key Output 1) will introduce 12-car trains on the Thameslink main line, and as a result further rolling stock will be required. This will partly filled by three 377/2 units to be borrowed from Southern in November 2011 until enough new rolling stock becomes available.

Political developments

Questions have been raised in the north London local press, and taken up by local politicians, over the decision not to extend the platforms for 12-carriage trains at three current Thameslink stations:
  • Hendon

. In the case of Kentish Town, the cost of having to rebuild one or other of the road bridges at the station is considered to be excessive.
