West Coast Main Line route modernisation

Last updated

The West Coast Main Line is a key strategic railway line in the United Kingdom. It links the cities of London, Glasgow, Birmingham, Liverpool, Manchester, Preston, Lancaster and Carlisle. Virgin Trains took on the franchise to run train services on the routes in 1997 and as part of the agreement wanted an upgrade to the railway line to allow for faster more frequent trains to grow the business. [1] The upgrade started in 1998 and was completed in 2009. [2] It came under parliamentary and media scrutiny because of cost and schedule overruns. [3] Further improvements such as the Norton Bridge rail flyover were completed after these dates. [4] The project is sometimes given the acronym WCRM - West Coast Route Modernisation. [5]

Previous modernisations

In the middle of the 20th century the line was upgraded substantially as part of the 1955 Modernisation Plan. [6] [7] Further electrification was discussed in 1968. [8] The line north of Crewe was modernised by further electrification from Weaver Junction to Glasgow in the 1970s. [9] [10] Some innovative electrical engineering technology was used on the project including lighter catenary and extensive use of headspans. [11] Substantial new signalling also took place in this timeframe. [12] The Advanced Passenger Train concept was in effect a part of that upgrade. It relied on tilting trains to increase speed on the route rather than major civil engineering interventions. [13] [14]

Post privatisation modernisation

The late 20th and early 21st century modernisation began without public sector involvement but with Railtrack. However, the Strategic Rail Authority was concerned about cost overruns. Railtrack asked the government for more money to complete the project but the Labour Party Secretary of State for Transport Stephen Byers put the company into liquidation. This and other problems with this project and its cost and time overruns, is usually considered the cause of the liquidation of Railtrack. [15] [16] In 2002 Bechtel was invited to join the project. [17] The upgrade went substantially over budget. [18] [19] Regular updates were then conducted by the UK Parliament accounts department. [20] The Strategic Rail Authority published a document in June 2003 which re-examined and clarified many of the assumptions and specified the direction and scope of the whole project. [21]

Benefits

The benefits of the project are claimed to be capacity improvements, journey time reductions of up to 28% in some cases and improved safety. [29] Although Virgin Trains were part of the driver for the project, the client is actually listed as the Department for Transport. The length of the project was just short of 11 years (110 months) and the final contract cost of approximately 9 billion pounds. [30] The Campaign for Better Transport (United Kingdom) has stated that the benefits are 1) Road congestion reduction. 2) Carbon emissions reduction. 3) Economic and 4) Passenger benefits. It is claimed it was part of the reason that the BBC decided to move its main operations from London to the north. [31]

Capacity enhancements

The Campaign for Better Transport (United Kingdom) in their paper entitled "Transformation of the West Coast Main Line" stated there are 40% more long distance services overall. There are 25% more between London and Scotland; 50% more between London and Birmingham and 150% more between London and Manchester. [32]

Safety

The removal and reduction of level crossings during the modernisation was one factor in improving the safety. A spokesperson for UK Railway Inspectorate made the statement in 2004 that "level crossings create the greatest potential for catastrophic risk on the railways". [33] Other crossings were also removed with subsequent reduction and modernisation of the overhead line. This also reduced maintenance costs.

Road congestion

Road congestion reduction has been harder to quantify but modelling that has been done suggests 26,000 fewer car journeys on the M1 and M40 motorways as a direct result along with as many as 7 million fewer car journeys between the cities of London and Manchester. [34]

Carbon emissions

On the London to Manchester route alone between 2009 and 2017, the modernisation resulted in a 77% increase in rail passengers; 23,000 tonnes of carbon saving and a 27% reduction in air passengers. The air passenger reduction was between Manchester and Heathrow, Gatwick, Stanstead and London City Airports. The number of flights between cities served by the WCML declined 67% since 2004 pre-COVID. [35]

Passenger benefits

In addition to journey time reductions, another result of the modernisation was an increase in capacity such that a 20 minute frequency of trains (3 per hour) between London and Manchester and London and Birmingham at key hours resulted. [36]

Issues - future work still needed

During modernisation, much of the signaling was renewed and concentrated in Rugby. However, money ran out and so the south end of the line still uses Wembley which controls assets that fail frequently. [37] This point of failure will need to be addressed in the future. Other upgrades are continuing. [38]

2020 onwards ongoing improvements

Carstairs has long being considered a bottleneck on the WCML and improvements including signalling, track renewal and other work finished in October 2022. Further work continued in 2023 and included work on the drains and embankments. [39] The work also included substantial realligning of tracks and platforms to give line speed increases [40] and needed a 12-week closure but was completed on time. [41] [42] [43]

More power-hungry trains and further electric freight means at many times there is an overload of the power supply on the WCML. Parts of the route, including Preston- Carlisle is sometimes called congested infrastructure due to power supply constraints. Future upgrades will be planned to enhance these. [44]

The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Liverpool, Manchester and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for 399 miles (642 km) and was opened from 1837 to 1869. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of 700 miles (1,127 km). The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh. However, the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Liverpool, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns.

The period from 1995 covers the history of rail transport in Great Britain following the privatisation of British Rail. During this period, passenger volumes have grown rapidly, safety has improved, and subsidies per journey have fallen. However, there is debate as to whether this is due to privatisation or to better government regulation. During this period, High Speed 1, the West Coast Main Line upgrade and Crossrail were completed and more construction projects are currently under way. The period also saw the demise of privately-owned Railtrack and its replacement with government-owned Network Rail.

<span class="mw-page-title-main">Midland Main Line upgrade</span> Ongoing railway upgrade in the United Kingdom

The Midland Main Line upgrade is an ongoing upgrade to the Midland Main Line (MML), a major railway line in the United Kingdom. There have been a number of proposals to electrify the line over many years but the 2012 proposal and announcement by the UK government was that it would include electrification of the railway line between Bedford, Wellingborough, Corby, Leicester, Derby, Nottingham and Sheffield. The routes between Nottingham and Sheffield and the Erewash Valley line were not included at this time, only the line between Derby and Sheffield. The upgrade was part of the HLOS - High Level Output Specification for Control Period 5 published by the UK Government in 2012. This was also part of a rolling programme of railway electrification projects. To enable all the benefits of using electric traction, the line south of Bedford into London St Pancras is also being progressively upgraded including boosting the power supply. Parts of the line have been classed as congested infrastructure hence another reason for the upgrade.

North West England electrification schemes are a series of individual railway lines in North West England that have been, and continue to be electrified and upgraded. It is planned that these schemes will result in a modernised, cleaner, lower carbon and faster railway with improved capacity.

The Felixstowe to Nuneaton railway upgrade in the United Kingdom is a series of upgrades being made to both a key strategic freight route and one that carries passengers on many parts. It is one of only two routes between the busiest container port and the Midlands, the other being via London. The route and the upgrade is sometimes abbreviated to F2N. The railway route includes the Birmingham–Peterborough line for a large part. The line links the Port of Felixstowe in Felixstowe, Suffolk, with the Midlands and crosses the East Coast Main Line, the Midland Main Line and the West Coast Main Line and thus the north and Scotland. From Nuneaton, a number of intermodal terminals may be reached. Much infrastructure in the UK is of Victorian origin and thus needed an upgrade; F2N, being a key route, is no exception.

Railway electrification in Scotland has proceeded in a different fashion than the rest of the UK especially in the 21st Century. There is political commitment to a substantial rolling programme of railway electrification from the Scottish government where transport is devolved. Transport Scotland and others have said "In Scotland, decarbonisation is spelt E-L-E-C-T-R-I-F-Y". All parties in Scotland are vigorously campaigning for electrification. As of January 2022, there are 2776 kilometres of track in Scotland, and 711 kilometres are electrified representing 25.3%. To meet these needs, the plan is to electrify on average 130 single track kilometres (STK) per year until 2035, although there has been some slippage in this target.
