High Speed 2 (HS2) is a proposed high speed railway in the United Kingdom serving The Midlands and North West with a possible "Y" shaped route from London to Birmingham and then spurs to Manchester and to Leeds via the East Midlands. The project is being developed by High Speed Two (HS2) Ltd, a company established by the UK government in January 2009. High speed rail is supported in principle by the three main UK political parties; there is however debate about which cities should be served and on the environmental performance and impact of high speed rail. If approved, construction would begin in 2017 with the first trains running by 2025. The only other high speed route in the UK is High Speed 1 (the Channel Tunnel Rail Link).
History
The Department for Transport published a document in January 2009 giving details of various options for a new high speed railway in the UK[n 1] and concluded that the most appropriate initial route for an entirely new high speed line in the UK was from London to the West Midlands.[n 2]
In January 2009 the government established a separate company, High Speed Two (HS2) Ltd chaired by Sir David Rowlands, to develop the project along the successful lines used for other long lead time rail infrastructure projects such as High Speed 1 and Crossrail.[n 3][n 4] The company would provide advice on the cost and benefits of a proposed route with any options as appropriate, options for a Heathrow International interchange station, options for access to central London and other cities on the route, connectivity with HS1 and the existing rail network, and proposals for financing and construction.[n 5]
In June 2009, Professor Andrew McNaughton, chief engineer for the HS2 suggested that any new line would need to be capable of 250-mile per hour (400 km/h) speeds.[1]
In August 2009, Network Rail published their own study outlining its proposals for the expansion of the railway network which included a new high speed rail line between London and Glasgow/Edinburgh, following a route through the West Midlands and the North-West of England.[2]
In December 2009, HS2 handed its report to the British government. Details released to the public showed proposals for a new railway station in London. Construction was listed as being possible to start by 2017, with completion of a first stage between London and the West Midlands by 2025. The study investigated the possibility for links to Heathrow Airport, connections to Crossrail, the Great Western Main Line and the High Speed 1 Channel Tunnel Rail Link. For the report, a route had been decided and investigated to an accuracy of 0.5 metres (18 in). The report was released in preparation for a government white paper expected to follow in April 2010.[3] The Conservative party accused Labour of delaying a decision until after the next election.[4]
Further details were announced on 11 March 2010 including a number of detailed reports.[5][6]
Route
The line would run from London Euston, mainly in tunnel, to an interchange with Crossrail, west of Paddington, thence along the New North Main Line (Acton-Northolt Line) past West Ruislip alongside the Chiltern Main Line with a four-kilometre viaduct over the Grand Union Canal and River Colne, from the M25 to past Amersham in a new 9.6 km tunnel. After emerging from the tunnel, the line would run parallel to the existing A413 road and London - Aylesbury line corridor, bypassing east of Great Missenden, west of Wendover and Aylesbury. After Aylesbury, the line would run alongside the Aylesbury line, joining north of Quainton Road and then taking over the dismantled stretch of this line, the Great Central Main Line, to Brackley.
Less studied are the routes of any possible extensions from Birmingham to Manchester and to Sheffield and Leeds which would allow connections to the North and Scotland. [n 6]
The route to the West Midlands would be the first stage of a line to Scotland[n 7] and passengers traveling to or from Scotland would be able to use through-trains with a saving of 45 minutes from day one.[7] If approved, construction would begin in 2017, with the first trains running by 2025.[8]
It is possible to view the route over Google satellite photography and on an OpenStreetMap map base. Note that the route may not be completely accurate as it has been traced from some very unclear and awkward to use PDF maps. The route can also be viewed using the official maps published by the DfT.
Possible connection to High Speed 1
Whether and how High Speed 2 should connect to High Speed 1 has not yet been decided. The government command paper says:
"... the new British high speed rail network should be connected to the wider European high speed rail network via High Speed One and the Channel Tunnel, subject to cost and value for money. This could be achieved through either or both of a dedicated rapid transport system linking Euston and St Pancras and a direct rail link to High Speed One."[n 8]
The route engineering study conducted by Arup for High Speed 2 costed a "classic speed" GC gauge direct rail link at £458m (single track) or £812m (double track). The connection would be from Old Oak Common to the High Speed 1 St Pancras portal, via tunnel and the North London Line. A double track high speed connection would cost £3.6bn.[9]
The High Speed 2 report recommended that if a direct rail link is built, it shoud be the classic speed, double track option.[10]
Journey times
Proposed journey times for some routes:[n 6]
London to... | Currently | Proposed |
---|---|---|
Birmingham | 1 hour 24 minutes | 49 minutes |
Manchester | 2 hours 8 minutes | 1 hour 20 minutes |
Liverpool | 2 hours 10 minutes | 1 hour 36 minutes |
Edinburgh | 4 hours 30 minutes | 3 hours 30 minutes |
Glasgow | 4 hours 30 minutes | 3 hours 30 minutes |
Proposed stations
Birmingham Curzon Street
A new station would be built partly on the site of the old Curzon Street Station, as the Birmingham terminus for High Speed 2. It would be reached via a spur line from the main route. The site is termed Birmingham Curzon Street in the government's command paper[n 9] and as 'Birmingham Fazeley Street' in the report produced by High Speed 2 Ltd with reference to a nearby street.[11] The two names do however refer to a station at the same location.
Curzon street was the main station for Birmingham until the nearby Birmingham New Street railway station was completed in the 1850s. Birmingham New Street is however already operating at full capacity and would be unable to accommodate new high speed services.
Birmingham Interchange
The March 2010 report proposes that a new "Birmingham Interchange" station would be built on the other side of the M42 motorway from the National Exhibition Centre, Birmingham International Airport and Birmingham International Station.[n 10] The new interchange would be connected by a "rapid transit people mover" to the other sites; the AirRail Link people mover already operates between Birmingham International station and the airport.
Crossrail interchange
The March 2010 report proposes that all trains would stop at a new "Crossrail interchange" located near Old Oak Common between London Paddington and Acton Main Line stations with connections for Crossrail, Heathrow Express and services on the Great Western Main Line to Heathrow Airport, Reading, South West England and South Wales. The Station also may also have connections with London Overground and Southern services on the North London and West London Lines and also with London Underground's Central Line[12]
London Euston
The line would terminate at an expanded London Euston which will serve both conventional rail and high speed rail. A rapid transit link between Euston and London St Pancras may be provided. The Command Paper also anticipates that the connection with Crossrail will mean that the prospective additional passenger load at Euston will be mitigated.
East Midlands "parkway" station
Not to be confused with East Midlands Parkway railway station on the Midland Main Line. A new "parkway" station in the East Midlands is also proposed at a new site (not the site of the current East Midlands Parkway station). It is not yet known where this station would be sited, as Sir David Rowlands of High Speed Two explained: "Taken individually, Nottingham, Leicester or Derby may not have adequate capacity for a high-speed line. They are not as big as Birmingham or Manchester ... but if you take them together, and have something that can serve all three, that's maybe the best way to go."[13]
Business leaders in the area supported high-speed rail coming to the East Midlands but were concerned that "If a station was connected to a city rather than a parkway it would cut connecting traffic ... The time it would take to get to a parkway would also negate the shorter journey times of the high-speed train itself.[13]
Infrastructure
It was announced that the proposed new line would use conventional steel rail technology to a European loading gauge capable of transporting "high cube" shipping containers[14] and double decker trains.
The route would be served by 400-metre long trains, carrying 1,100 passengers at up to 200 miles per hour (320 km/h).[15]
Environmental impact
Environmental degradation
There are concerns that the route is likely to damage the Chiltern Hills area of outstanding natural beauty, the Colne valley regional park on the outskirts of London and other areas of green belt.[16]
The proposals also include the re-alignment of over 1 kilometre of the already re-aligned River Tame, construction of a 635-metre long viaduct and a large cutting through ancient woodland at the The Wildlife Trust for Birmingham and the Black Country nature reserve at Park Hall on the edge of Birmingham[17].
The scheme would result in the demolition of 440 homes; 250 around Euston station, 'dozens' in West London and most of the rest in Birmingham. The Government has announced plans to compensate those affected by the route who have a "pressing need to sell their homes" but are unable to do so after a period of three months. After May 2010, homeowners who can't sell their houses while the scheme is in the planning stage can apply to have the property bought at market value by High Speed 2. The compensation scheme would remain in place until the project received formal planning approval at which point compensation would be handled by existing measures aimed at homeowners affected by major strategic projects. [18]
Carbon emissions
In 2007 the Department for Transport commissioned a report to investigated likely the carbon impacts associated with the construction and operation of a new rail line to either Manchester or Scotland, and in particular the comparison with emissions from domestic flights, when airport infrastructure carbon costs are discounted.
The report concluded that there were "no potential carbon benefit in building a new line on the London to Manchester over the 60-year appraisal period. In essence, the additional carbon emitted by building and operating a new rail route is larger than the entire quantity of carbon emitted by the air services".[n 11] It did also note that "Construction emissions are only considered for the new line rail options, no construction emissions are assumed for domestic air."[n 12] The report, "Estimated Carbon Impact of a New North South Line", was commissioned from Booz Allen Hamilton.[n 13]
The "High Speed Rail Command paper" published in March 2010 estimated that the carbon impact of the scheme would be between -25.0 to +26.6 MtCO2 over a 60-year period and noted that the figures would be very sensitive to the assumptions relating to load factor, the modal shift achieved away from aviation and the carbon intensity of electricity generation. Should no reduction in aviation be achieved and if there was no change to carbon intensity of electricity generation then the scheme would increase emissions by 0.44 million tonnes per year.[n 14]
Management
High Speed 2 Ltd
High Speed Two (HS2) Ltd was established in January 2009,[n 15] to study the feasibility and viability of a new line[n 16] using trains capable of travelling at speeds over 150 miles per hour (240 km/h).[n 17] The company's stated purpose was to "help consider the case for new high speed services from London to Scotland."[n 18] As a first stage, initial proposals for a new line would be considered for routes between London and the West Midlands,[n 18][n 19] with the new line extended over time to reach Scotland.[n 20] The company would report formally to the Government on the initial issues affecting this first stage by the end of 2009.[n 21]
The company would draw on existing consultation produced for the Department for Transport (DfT) and Network Rail, soliciting new consultation where needed, and would utilise Department for Transport and Network Rail staff as well as recruiting externally.[n 3] While the project was launched as an independent initiative, in launching the HS2 company the government acknowledged the contributions of both the consultancy group Arup in suggesting a high speed link from Heathrow to London, and of HSR advocacy group Greengauge 21 in justifying High Speed rail based on the limitations of the WCML, as both having been important.[19]
The board consists of:[20]
- Sir David Rowlands - Non-Executive Chairman
- Alison Munro - Chief Executive and Board Member
- Sir Brian Briscoe - Non-Executive Board Member
- Andy Friend - Non-Executive Board Member
- Mike Welton - Non-Executive Board Member
- Tim Wellburn - Non-Executive Board Member
Alternative proposals
The intention of the chosen scheme is to relieve congestion on the motorways, rather than replicating an existing route such as the West Coast Main Line.[n 22] and the selected route was identified as "the single most important and heavily used" strategic national transport corridors in England, for both passenger and freight traffic by road and rail,[n 23] with the corridor being cited as having twice the size of travel market as London to the North West and six times that of London to Scotland.[n 24] The DfT cited the significant rail market share (52%) of North East England, "a region well served by efficient and reasonably fast rail services", as showing that the new line could achieve a "modal shift" to rail, from road and air.[n 25]
In launching the project the DfT announced that the new High Speed 2 line between London and the West Midlands would follow a different alignment to the existing WCML, because it was considered to be too costly to provide extra capacity by building new rail alongside the existing WCML while the existing track was in use. Furthermore, parts of the existing Victorian era WCML alignment were not suitable for High Speed Rail service.[n 26]
The Government stated that the new line would improve rail services from London to "Manchester, Liverpool, Glasgow and other destinations in the north of England and Scotland",[n 27] and an approach route west of London would allow opportunities to "improve surface access by rail to Heathrow Airport."[n 28] Furthermore, if the new line were connected to the Great Western Main Line (GWML) and Crossrail it would provide links with East and West London, and the Thames Valley.[n 29]
The DfT also said that the West Coast Main Line (WCML), the existing UK main railway line serving the corridor, was the United Kingdom's busiest, but was expected to be "overloaded south of Rugby by about 2025".[n 30] This was despite a recently completed upgrade, and the expected implementation of plans for longer trains and in-cab signalling.[n 31] Specifically for the WCML as opposed to other main lines, it was asserted that no further significant capacity enhancements were possible without "major disruption to passengers and freight services".[n 26] It was proposed that released capacity on the existing WCML due to construction of HS2 would then be used to enhance services for the Northampton, Milton Keynes and South Midlands area, identified as the "largest growth area in the UK" with a population of 1.6-million people.[n 32]
Atkins study
The Atkins study had identified routes to the West Midlands, Liverpool and Manchester as being capacity constrained by 2015 and this is almost certainly where the first HSL will be required. Atkins also recommended having two routes, one each side of the Pennines. The study recommends against a trunk and branch structure.
Network Rail proposal
A Network Rail study published in August 2009 proposed an alternative high speed route to Scotland via the north west which would replace the West Coast Main Line making it[vague] available for regional services. The report did not find in favour of the line running through Heathrow airport, but favoured a high-speed spur to the airport.[21]
Maglev
A line using maglev technology was dismissed as being too costly to build, not as environmentally friendly as conventional high-speed rail, unable to integrate with the existing UK rail network or future high-speed lines, and unable to bring the operational flexibility and advantages of conventional high speed rail, such as the development of domestic services on HS1 which use high-speed railways in part.[n 33]
