Thameslink Programme

The Thameslink Programme, formerly known as Thameslink 2000, is a £5.5 billion major project to upgrade and expand the Thameslink rail network in southern England.cite web| url=http://www.gnn.gov.uk/environment/fullDetail.asp?ReleaseID=302259&NewsAreaID=2&NavigatedFromDepartment=False| author=Government News Network| year=2007-07-24| title=Resurgent railway gets strategy for 30 years of growth| accessdate=2007-07-24] The project includes the lengthening of platforms, station remodelling, new railway infrastructure and additional rolling stock.

Project history (pre-construction)

Background

The Thameslink rail network was created by joining the electrified network south of the Thames with the recently electrified line between Bedford and St. Pancras to the north via the Snow Hill tunnel. It was fully inaugurated in May 1990, two years after services began. [cite web| url=http://www.subbrit.org.uk/sb-sites/stations/s/snow_hill/index.shtml| author=Nick Catford| year=2006-02-10| title=Station Name: Snow Hill/Holborn Viaduct Low Level| accessdate=2006-11-28] Thameslink is the only National Rail service that crosses the centre of London. This reduces the need to use the Underground for cross-London journeys. [cite web| url=http://www.firstcapitalconnect.co.uk/pages/destinations/network-map/default.aspx| author=First Capital Connect| year=2006-04-01| title=Network and Stations| accessdate=2006-11-28] As a direct result of its inception, journeys between destinations in north and south London that were served by Thameslink services quadrupled after the first year of operation. [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 29, paragraph 4] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-12-13|format=PDF]

A consequent unusual feature of its history is that all through services need to be operated by dual-voltage trains since the original lines south of the river are electrified using a 750 volt third rail and those to the north by the more modern 25kV overhead system. All plans for development as well as day-to-day operation of the line are constrained by this.

Initial planning

The increasing patronage was seen as a potential problem for the network, given that £4 million was spent on infrastructure that was built for the network. [cite web| url=http://www.railwaypeople.com/rail-projects/thameslink-2000-19.html| author=RailStaff| year=2004-06-01| title=Thameslink 2000| accessdate=2006-11-28] As a result, British Rail started developing plans to expand and upgrade the original network during the early 1990s. The Railways Act of 1993 meant that responsibility for the project was transferred to Railtrack in the mid 1990s, but privatization combined with a recession in the UK economy caused the first of many delays to the project which was initially envisaged to be complete by 2000 (hence the original name).

Beginning of planning process

Railtrack applied for Transport and Works Act powers on 21 November 1997.cite web| url=http://www.parliament.the-stationery-office.com/pa/cm200102/cmwib/wb021026/trans.htm| author=House of Commons| year=2002-10-26| title=Transport and Works Act 1992 Orders| accessdate=2006-12-07] Just two months later, the prospects of Thameslink 2000 becoming reality were thrown into doubt because London and Continental Railways (LCR), a new company that was appointed by the Government to construct High Speed 1 announced that they required further direct government grants worth £1.2 billion (in 1995 real prices) to finance the construction of the CTRL.cite web| url=http://www.nao.org.uk/publications/nao_reports/00-01/0001302.pdf| author=National Audit Office [see page 6, paragraph 2] | year=2001-03-28| title=The Channel Tunnel Rail Link| accessdate=2006-12-07|format=PDF] As part of the Channel Tunnel Rail Link Act of 1996, LCR were under obligation to build a concrete 'box', which was to house a new sub-surface station that was proposed as part of Thameslink 2000, since the new station would be built under St Pancras station itself.

The Government and LCR reached agreement on a set of revised proposals in June 1998, which allowed the construction of CTRL (and the concrete box) to proceed. Meanwhile Railtrack took the opportunity to carry 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.

First public inquiry

Given the size of the project, the Deputy Prime Minister decided to call for a public inquiry, which commenced in June 2000 and was brought to a close in May 2001. [cite web| url=http://www.networkrailmediacentre.co.uk/Content/Detail.asp?ReleaseID=2408&NewsAreaID=2&SearchCategoryID=2| author=Network Rail| year=2006-10-18| title=The £3.5bn Thameslink Project Clears Major Hurdle| accessdate=2006-11-20] 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) published the Inspector's report, which stated that although there was a strong case for the project, the Inspector did not recommend that the project should be given approval, [cite web| url=http://www.communities.gov.uk/pub/763/47Recommendations_id1143763.pdf| author=Department for Communities and Local Government| year=2006-07-30| title=Recommendations| accessdate=2006-11-20|format=PDF] since there were three 'deficiencies' that he was not satisfied with:
*The poor quality proposals for the redevelopment of London Bridge station;
*The lack of proposals for the 'missing tooth' near Blackfriars station;
*The lack of proposals for the replacement of listed buildings around the historic area of Borough Market.

Further delays

As a result the Deputy Prime Minister stated that the project would not receive approval and that Network Rail (which replaced Railtrack) was required to submit an improved set of proposals (i.e. with no deficiencies) and a new Environmental Statement on January 29 2003. [cite news| url=http://news.bbc.co.uk/1/hi/england/2707345.stm| publisher=BBC News| date=2003-01-29| title=Serious setback for cross-London rail route| accessdate=2006-11-21] As a result of lack of progress on the project, the 'Thameslink 2000 Agreement', a contract that obliged Network Rail (and previously its predecessor Railtrack) to maintain responsibility for funding the project, was terminated in April 2003. Responsibility for project funding was subsequently transferred to the Strategic Rail Authority.Fact|date=April 2007

Nevertheless, Network Rail made adjustments to the Thameslink 2000 proposals and in June 2004 they submitted the aforementioned proposals, along with an updated Environmental Statement (dated 14 June 2004 [cite web| url=http://www.tl2000inquiry.org.uk/documents/cd165.pdf| author=Network Rail [see page 3] | date=2004-06-14| title=Thameslink 2000 Environmental Statement: Main report appendix – summary of significant changes| accessdate=2006-12-13|format=PDF] ). On 22 March 2005 the Deputy Prime Minister and the Secretary of State for Transport called for a new public inquiry in light of the amendments and also confirmed that it would commence in September 2005. [cite web| url=http://www.networkrailmediacentre.co.uk/Content/Detail.asp?ReleaseID=123&NewsAreaID=2| author=Network Rail| date=2005-03-22| title=Network Rail Welcomes Confirmation of Date for a New Public Inquiry About the Thameslink Programme| accessdate=2006-11-27]

As a result of the Railways Act of 2005, the Department for Transport (DfT) took over funding responsibility for the project from the Strategic Rail Authority on 25 July 2005.cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see footnote 1 on page 4] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-21|format=PDF]

Second public inquiry

The second public inquiry commenced on 6 September 2005 and was brought to a close in December 2005. [cite web| url=http://www.networkrailmediacentre.co.uk/Content/Detail.asp?ReleaseID=50&NewsAreaID=2| author=Network Rail| year=2005-12-09| title=Thameslink Inquiry Closes| accessdate=2006-11-28] The Inspector's report (dated 17 February 2006 [cite web| url=http://www.dft.gov.uk/pgr/twa/ir/thameslinkreport/thameslink2000inspectorsrepo1034?page=1| author=Department for Transport| year=2006-10-18| title=Thameslink 2000 Inspector's Report 2006| accessdate=2006-11-28] ) was subsequently submitted to the DfT for consideration. On 18 October 2006, the DfT published the second report, which declared that the Inspector was satisfied that the deficiencies from the previous Thameslink 2000 proposals were dealt with, and that he recommended that the project be given approval. [cite web| url=http://www.dft.gov.uk/pgr/twa/ir/thameslinkreport/thameslink2000inspectorsrepo1034?page=43| author=Department for Transport [see paragraph 19.13] |year=2006-10-18|title=Thameslink 2000 Inspector's Report 2006|accessdate=2006-11-23]

Project approval

In conjunction with the second report, the Secretaries of State for Transport and 'Communities & Local Government' consequently granted Network Rail the planning permission and legal powers required to execute the project, and the Order (officially described as "The Network Rail (Thameslink 2000) Order 2006") came into force on 13 December 2006; [cite web| url=http://www.opsi.gov.uk/si/si2006/20063117.htm| author=Office of Public Sector Information| year=2006-12-01| title=The Network Rail (Thameslink 2000) Order 2006| accessdate=2007-04-24] furthermore, on 19 December 2006, the Parliamentary Under-Secretary of State for Transport announced that the DfT would grant Network Rail £30 million to 'enable a more informed decision to be made regarding the case for funding the implementation of the project in summer 2007'. [cite web| url=http://www.publications.parliament.uk/pa/cm200607/cmhansrd/cm061219/wmstext/61219m0002.htm#06121936000102|author=United Kingdom Parliament|year=2006-12-19|title=Publications and Records|accessdate=2007-04-24]

On 24 July 2007, the Secretary of State for Transport, Ruth Kelly, formally announced that the Government was fully committed to funding the Thameslink Programme. Since the planning permission and legal powers associated with the project have already been granted, the project is now clear to proceed.

Summary of project phases

To minimise the risk, the Thameslink Programme will be divided into 3 phases.

Key Output 0

Works are being carried out to permit the current 15tph peak hour service between St. Pancras and Farringdon to be extended at least as far south as Blackfriars, since services to/from Moorgate and Blackfriars will be merged from March 2009.cite web| url=http://www.firstcapitalconnect.co.uk/Main.php?iCmsPageId=261&sMethod=ViewArchive&iForumId=7&iSectionId=18|author=First Capital Connect|title=FAQs|accessdate=2008-04-09] This involves 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 will terminate at Kentish Town or further north, and it is intended that dual-voltage Class 377 Electrostars will be procured in order to help fulfil the additional rolling stock requirements.Ian Allan Publishing. "Modern Railways". March 2008 page 34".] .

Key Output 1

A major aim of the project is to allow the introduction of 12-car trains on the Thameslink network. Platform extension works will be required at around 50 stations,cite web| url=http://www.networkrail.co.uk/aspx/1326.aspx| author=Network Rail| date=2006-10-18| title=Thameslink Programme| accessdate=2006-11-29] particularly north of the Thames on the existing Thameslink route where all stations (with the exception of St Pancras and City Thameslink) are currently restricted to a maximum length of 8 cars; these works commenced at Luton Airport Parkway on 24 October 2007cite news| url=http://news.bbc.co.uk/1/hi/england/london/7059432.stm| author=BBC News| date=2007-10-24| title=Work begins on Thameslink project| accessdate=2007-10-24] and will be carried out at another 22 stations until 2011. Platform extensions at Farringdon and Blackfriars will also be provided as part of major remodelling works, which are due to commence in January 2009.

The second aim is to increase the capacity of the central London section in terms of trains per hour. A new viaduct will be built over Borough Market to provide trains to Blackfriars and trains to Charing Cross with their own dedicated routes."Thameslink aims for Olympic gold", pages 41-47. Modern Railways, February 2007] All of the above is planned to take place prior to the 2012 Olympics and would result in 10,000 extra peak period seats from December 2011."Halfway-house Thameslink for Olympics?", page 6. Modern Railways, April 2006]

Key Output 2

After the Olympics London Bridge will be subject to major track, signalling and station remodelling works as part of the "Masterplan" project (some works within the station building may commence during Key Output 1). New permanent way (both plain rail and junctions) and overhead line equipment will be laid out in the new Canal Tunnels between the Thameslink route and the East Coast Main Line,"Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 61, paragraph 2.14.4. Network Rail, June 2004] consequently opening up the network to new destinations north of Central London. The fly-down at Tanners Hill will be widened and become double trackand a grade separated junction will be created at Bermondsey. 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) between St Pancras and Blackfriars from December 2015, which equates to an extra 14,500 peak period seats when compared to the current level of service.cite web| url=http://nds.coi.gov.uk/environment/fullDetail.asp?ReleaseID=364954&NewsAreaID=2&NavigatedFromDepartment=False| author=News Distribution Services| year=2008-04-09| title=14,500 extra seats for Thameslink passengers| accessdate=2008-04-23]

As part of the project a purpose built fleet of 1100 vehicles (equivalent to 275 4-car trains) would operate across the network - for which the procurement process commenced on 9 April 2008. Due to the additional power requirements of this new fleet, electricity supply enhancement works across the network will be carried out during most of the entire project - this will be achieved by 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.

Major project works

King's Cross Thameslink / St Pancras

The previous station King's Cross Thameslink closed in 2007 and trains now stop at St Pancras. The need for a replacement station arose due to factors regarding King's Cross Thameslink such as substandard platform widths and lengths, lack of step-free access, lack of easily accessible fire escape routes and a poor quality passenger environment. [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 20, paragraph 5.4.1] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-21|format=PDF] If the previous station had been upgraded to modern standards, it would have required in excess of £60 million (which is similar to the cost of fitting out the new station anywaycite web| url=http://www.gnn.gov.uk/environment/fullDetail.asp?ReleaseID=186870&NewsAreaID=2&NavigatedFromDepartment=False| author=Government News Network| year=2006-02-08| title=Thameslink Passengers to Get New Station at St. Pancras| accessdate=2006-11-20] ) and serious disruption on the nearby Circle/Hammersmith & City/Metropolitan LUL lines and roads would have occurred as a direct consequence. [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 20, paragraph 5.4.2] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-21|format=PDF]

The new station accepts 12 car trains (the previous station was limited to 8 cars) and allows better interchange with other forms of transport, particularly Eurostar. It also has a CCTV system, seven escalators and two lifts, which allows people with impaired mobility to use the station. 'Fit-out' works began in the summer of 2006 (following the decision by the DfT to provide a further £60-65 million for the High Speed 1 project), and operations commenced on 9 December 2007. [cite web| url=http://www.firstcapitalconnect.co.uk/Main.php?iCmsPageId=77| author=First Capital Connect| year=2007-04-01| title=St Pancras International| accessdate=2007-04-24]

Due to the planned closure of King's Cross Thameslink, passengers who were using the station to access the Underground lines would have had to proceed to the other entrances to King's Cross St Pancras in order to access the lines once Thameslink service calls at King's Cross Thameslink were discontinued (although the station would have been retained as an emergency exit, which remains the case today). For this reason, London TravelWatch recommended that the Thameslink station should be retained as an entrance/exit facility for London Underground passengers. [cite web| url=http://www.londontravelwatch.org.uk/document/2305/get| author=London TravelWatch [see page 5, paragraph 6.11] | year=2005-11-01| title=Proposed closure of King’s Cross Thameslink station and parts of the railway network at Blackfriars station and London Bridge station| accessdate=2007-12-15]

London Underground agreed with the recommendation but stated that funding for the required modifications would need the agreement of the DfT; in response the DfT decided against pushing this forward, stating that it was a matter for Transport for London (TfL) [cite web| url=http://www.dft.gov.uk/pgr/rail/pi/tl2000/thameslink2000closuredecision| author=Department for Transport [see page 10, paragraph 43] | year=2006-10-18| title=Thameslink 2000 - Proposal to Discontinue Passenger Services, Close Parts of a Network, Close Parts of Stations and Terminate Use of a Station| accessdate=2006-11-21] . Since 10 December 2007 (the day after Thameslink service calls at King's Cross Thameslink were discontinued), the old station entrance has been retained as part of King's Cross St Pancras. [cite web| url=http://www.tfl.gov.uk/corporate/projectsandschemes/stationsandinterchanges/2333.aspx| author=Transport for London| title=King's Cross St Pancras| accessdate=2007-12-09]

Farringdon & the Moorgate branch

Farringdon station is limited to 8 cars, and therefore requires platform extensions to handle 12 car trains. Extensions towards the north are not planned mainly due to the steep gradient (1 in 27) of the Thameslink line immediately north of Farringdon.cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 9, paragraph 2.1.5] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-12-07|format=PDF] Northward platform extensions therefore would not comply with safety standards, which leaves the alternative of realigning both the Thameslink and Circle/Hammersmith & City/Metropolitan LUL lines, given that the latter crosses over the former on a bridge. This has been deemed impractical due to lack of space. The platforms will therefore be extended southwards, severing the two-station branch to Moorgate. [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 9, paragraph 2.1.1] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-23|format=PDF]

The buildings at 54-60 Cowcross Street will be demolished and a new ticket hall and concourse for National Rail passengers will be built in their place; furthermore, the existing listed ticket hall and concourse will be remodelled, but it will be used exclusively by LUL passengers."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 27, paragraph 2.6.3. Network Rail, June 2004] Despite the separate functions of the two station buildings, interchange within the station will be improved by means of removing the existing interchange bridge and installing new stairs and lifts with access to all four platforms, thereby allowing passengers with impaired mobility to use the station."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 27, paragraph 2.6.4. Network Rail, June 2004]

The increasing patronage at Farringdon also necessitates the widening of the platforms, which itself requires the Cowcross Street bridge abutments to be shifted; for this reason the bridge will be demolished and then rebuilt once the abutments have been shifted."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 27, paragraph 2.6.5. Network Rail, June 2004] Other planned major works within Farringdon include the erection of a new roof over the northern half of the station premises and the pedestrianisation of Cowcross Street. [cite web| url=http://www.tl2000inquiry.org.uk/documents/cd202.pdf| author=Network Rail [see page 15, paragraph 2.2.1] | year=2005-07-01| title=Thameslink 2000 Environmental Statement: Addendum| accessdate=2006-12-13|format=PDF] This is to help passenger movements around and within the station, particularly during the peak; and to protect passengers from the weather.

The intermediate station at Barbican (which is located on the Moorgate branch) is already used by Thameslink trains only when travelling east (from Farringdon); westbound trains (from Moorgate) do not stop. Once the branch is closed in March 2009 passengers wanting to travel to or from Barbican or Moorgate stations will have to change at Farringdon onto London Underground trains on the Circle/Hammersmith & City/Metropolitan LUL lines. Although this will be inconvenient for some passengers (the disbenefits are estimated at £65 million over a 60 year appraisal period [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 10, paragraph 2.4.2] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-23|format=PDF] ), the benefits to other Thameslink passengers are deemed to be significantly greater (£5.7 billion over the same period [cite web| url=http://www.dft.gov.uk/stellent/groups/dft_railways/documents/page/dft_railways_610223.pdf| author=Network Rail [see page 11, paragraph 2.5.5] | year=2005-11-04| title=Thameslink 2000 Closures Statement of Reasons| accessdate=2006-11-23|format=PDF] ).

City Thameslink

No major works will take place within City Thameslink railway station, although the OLE (overhead power) system will be extended from Farringdon to City Thameslink for northbound trains only. Combined with new trackwork between the two stations, this will allow northbound trains to be recovered should they fail to change from the southern portion's third rail DC to the northern portion's overhead AC traction current (and vice versa). [cite web| url=http://www.dft.gov.uk/pgr/twa/ir/thameslinkreport/thameslink2000inspectorsrepo1034?page=6| author=Department for Transport [see paragraph 2.2.16] | year=2006-10-18| title=Thameslink 2000 Inspector's Report 2006| accessdate=2006-11-28]

Blackfriars

The existing building at 167-179 Queen Victoria Street (which is currently utilised as an LUL office) will be demolished and, a new station building (which will employ a facade primarily composed of glass) will be built in its place, to the same height. Within this building a new shared National Rail/LUL ticket hall and LUL ventilation shaft will be provided; in addition, new escalators and lifts will take passengers to a mezzanine level (for National Rail services) or to a sub-surface level (for the Circle/District LUL lines)."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 34, paragraph 2.7.6. Network Rail, June 2004] The LUL station will also be subject to major enhancements, and therefore will be closed for 24 months. [cite web| url=http://www.dft.gov.uk/pgr/twa/dl/thameslink/thameslink2006transportandwo1036?page=3| author=Department for Transport [see paragraph 35] | year=2006-10-18| title=Thameslink - 2006 Transport and Works Act Decision Letter| accessdate=2006-12-07] The existing subway entrance to Blackfriars station will be permanently closed as a result of the Thameslink Programme.

The through platforms will be extended along Blackfriars Railway Bridge over the River Thames in order to accommodate 12 car trains (in place of 8 today). The platform layout will also be altered such that the through platforms will be located on the east side of the station (currently the west side), and the terminus platforms will be located on the west side of the station (currently the east side).cite web| url=http://www.alwaystouchout.com/project/23| author=alwaystouchout.com| year=2006-10-28| title=Thameslink Programme (Thameslink 2000)| accessdate=2006-11-27] This means trains to and from London Bridge will no longer have to cross the lines that lead to the bay platforms, which is currently a source of delays.

In order to accommodate the new/extended platforms the existing bridge deck will be strengthened and widened towards the west - consequently the easternmost line of disused piers (which supported the former West Blackfriars and St Paul’s RailwayBridge) will themselves be strengthened, tied into the existing bridge and become stone clad. [cite web| url=http://www.tl2000inquiry.org.uk/documents/cd191.pdf| author=Network Rail [see page 16, paragraph 2.15] | year=2005-03-01| title=Thameslink 2000 Statement of Case March 2005| accessdate=2007-12-15|format=PDF] The number of bay platforms will be reduced from 3 to 2 in the process, but some terminating services will become through services, and the increased length will allow longer trains to terminate at Blackfriars. The existing station roof will be demolished and replaced by a new roof of glazed north lights and partial height glazed side panels, which will be installed along the entire length of the bridge. In addition there will be a new station entrance on the South Bank, where a second ticket hall will be provided."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 35, paragraph 2.7.9. Network Rail, June 2004] The project is being designed by Jacobs and Tony Gee and Partners and being built by Balfour Beatty.

Borough Market Viaduct

The two-track Borough Market Viaduct west of London Bridge is currently used by trains on the Thameslink route to Blackfriars and all trains to Charing Cross. This causes a major bottleneck in the area. To relieve this, an additional pair of tracks will be added to this short section of the route. Trains to Charing Cross will use the southern pair of tracks. This will give Thameslink trains a dedicated route to Blackfriars on the northern pair, which is key to providing the nominal peak hour frequency of 24tph on the core route.

Between London Bridge and the vicinity of Stoney Street, the extra pair of tracks will be on a new viaduct to the south of the existing one. This will require the demolition (and subsequent replacement) of a group of listed buildings within Borough Market, which is a conservation area. West of Stoney Street, most of the widening of the existing viaduct will be to the north, to avoid affecting the Hop Exchange building to the south.

London Bridge

London Bridge station will undergo a major transformation as part of a wider project known as "Masterplan". One aspect of the proposals involves the closure of 3 terminus platforms and the creation of 3 through platforms to allow additional services to continue to either Cannon Street, Charing Cross or Thameslink stations north of the River Thames. The increase in through platforms will also allow London Bridge to function as an emergency terminus for services approaching the station from the west.

To alleviate congestion and improve circulation within the station, a new station concourse will be built. This requires the demolition of brick vaults between Stainer and Weston Streets, which will themselves become part of the new concourse (and therefore cease to be thoroughfares).

As a result of changes that have been made to signalling standards, the current throughput of train services at London Bridge during the peak may have to be reduced if the signalling system is renewed in the absence of the Thameslink Programme.

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 can cross over trains from Kent headed for Charing Cross.

Charing Cross services will be diverted slightly south in the vicinity of Trundleys Road onto the route of the former branch line to Bricklayers' Arms. They will then slope up alongside the Brighton Main Line just north of South Bermondsey station. Thameslink trains can then cross over the line on a new bridge, meeting the existing alignment just north of Jarrow Road. The Charing Cross line and Thameslink will each cross the Rotherhithe New Road on the other's present alignment.

Tanners Hill fly-down

In order 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."Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 53, paragraph 2.11.1. Network Rail, June 2004] Before the new track is laid, St John’s Vale Road Bridge will be subject to partial demolition and will be reconstructed with a concrete pier, as well as a new south span over the new track; the existing embankment along the fly-down will also be widened. Given that the existing footbridge will be rebuilt, a temporary footbridge will be provided for the duration of the works. "Thameslink 2000 Environmental Statement: Main report (Inner Area)", page 53, paragraph 2.11.3. Network Rail, June 2004]

Rolling stock

As of 2008, the existing Thameslink fleet consisted of 74 dual-voltage Class 319s and 2 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 cascade of 12 Class 319s to be implemented in batches of 4 and 8 during December 2007 and December 2008 respectively. Now that project funding is guaranteed, it is now also intended that 23 Class 377s will be drafted in to fulfil further capacity requirements that will come into play once the service alterations of Key Output 0 are in place.

The December 2011 timetable (i.e. after Key Output 1) will introduce 12-car trains and as a result further rolling stock will be required.

The Thameslink Rolling Stock Project (itself a part of the Thameslink Programme) commenced on 9 April 2008 and it was introduced for the purpose building a brand new fleet of electric trains worth £1.4 billion.
