Product Code Database
Network Rail Limited is the owner and infrastructure manager of most of the railway network in Great Britain. Network Rail is a non-departmental public body of the Department for Transport with no shareholders, which reinvests its income in the railways.
Network Rail's main customers are the train operating companies (TOCs), responsible for passenger transport, and freight operating companies (FOCs), who provide train services on the infrastructure that the company owns and maintains. Since 1 September 2014, Network Rail has been classified as a "public sector body".
To cope with rapidly increasing passenger numbers, () Network Rail has been undertaking a £38billion programme of upgrades to the network, including Crossrail, electrification of lines and upgrading Thameslink.
In May 2021, the UK government announced its intent to merge Network Rail's responsibilities with other railway operations into a new public body called Great British Railways.
A spate of accidents, including the Southall rail crash in 1997 and the Ladbroke Grove rail crash in 1999 called into question the negative consequences that the fragmentation of the railway network had introduced to both safety and maintenance procedures. Railtrack was severely criticised for both its performance for infrastructure improvement and for its safety record. The Hatfield train crash on 17 October 2000 was a defining moment in the collapse of Railtrack. The immediate major repairs undertaken across the whole British railway network were estimated to have cost in the order of Pound sterling580million and Railtrack had no idea how many more 'Hatfields' were waiting to happen because it had lost considerable in-house engineering skill following the sale or closure of many of the engineering and maintenance functions of British Rail to external companies; nor did the company have any way of assessing the consequence of the speed restrictions it was ordering. These restrictions brought the railway network to an almost total standstill and drew significant public ire. According to railway historian Christian Wolmar, Railtrack's board panicked in the wake of Hatfield. Railtrack's first chief executive, John Edmonds, had pursued a deliberate strategy of outsourcing engineers' work wherever possible with the goal of reducing costs.
Various major schemes being undertaken by Railtrack had also gone awry. The modernisation of the West Coast Main Line had suffered from spiralling costs, rising from an estimated £2billion to roughly £10billion. This programme suffered failures that were technical as well as managerial, such as the moving block signalling apparatus being immature for such a busy mixed-traffic mainline. In 2000, reports emerged that Railtrack may not be able to go through with its planned commitment to purchase section 2 of High Speed 1, resulting in disruption and uncertainty for that programme as well.
In February 2001, Steve Marshall, Railtrack's chairman, warned that Railtrack could have a net debt of approximately £8billion by 2003. During May 2001, Railtrack announced that, despite making a pre-tax profit before exceptional expenses of £199m, the £733m of costs and compensation paid out over the Hatfield crash had plunged Railtrack from profit into a loss of £534m, and it approached the government for funding, which it controversially used to pay a £137m dividend to its in May 2001. Months later, Railtrack sought another bailout from the government. On 7 October 2001, Railtrack plc was placed into railway administration under the Railways Act 1993, following an application to the High Court by the then Transport Secretary, Stephen Byers.
Network Rail owns the infrastructure, including the railway tracks, signals, overhead wires, tunnels, bridges, level crossings and most stations, but not the passenger or commercial freight rolling stock, other than its limited departmental stock. While it owns over 2,500 railway stations, it manages only 20 of the biggest and busiest of them as all the other stations are managed by the various train operating companies (TOCs). Network Rail should not be confused with National Rail, the latter is a brand rather than an organisation, used to inform and promote a nationwide network of passenger railway services. The majority of Network Rail lines also carry freight traffic; some lines are freight only. A few lines that carry passenger traffic are not part of the National Rail network (such as the Tyne and Wear Metro and the London Underground). Conversely, a few National Rail services operate over track which is not part of the Network Rail network, such as the line between Harrow-on-the-Hill and Amersham station being owned by London Underground.
Following an initial period in which Network Rail established itself and demonstrated its competence in addressing the principal challenges of improving asset condition, reducing unit costs and tackling delay, the Government's Rail Review in 2004 said that Network Rail should be given responsibility for whole-industry performance reporting, timetable development, specification of small and medium network enhancements, and the delivery of route-specific utilisation strategies (RUS). Some of these are functions which Network Rail already had; others – such as the obligation to devise route utilisation strategies – were transferred to Network Rail from the Strategic Rail Authority, a non-departmental public body, part of the UK government. The SRA was abolished in November 2006.
Network Rail initially sub-contracted much of the infrastructure work to private maintenance companies, such as Carillion and First Engineering; other sub-contractors perform specialist work or additional labour, such as Prima Services Group, Sky Blue, Balfour Beatty, Laboursite, BCL, Atkins (Atkins Rail) and McGinleys. In October 2003, Network Rail announced that it would take over all infrastructure maintenance work from private contractors, following concerns about the quality of work carried out by certain private firms and spiralling costs. In 2007, it was announced that the number of track renewal contractors would be reduced from six to four; Amey plc/Seco Rail, Balfour Beatty, Babcock First Engineering and Jarvis plc. Network Rail has expanded its in-house engineering skills, including funding of apprenticeship and foundation degree schemes, and has reported significant savings from transferring work away from contracting companies. Additional work was taken back in-house after the serious accident at Potters Bar and other accidents at Rotherham and King's Cross led to Jarvis's collapse into administration in March 2010.
The company moved its headquarters to Kings Place, 90 York Way, from 40 Melton Street, Euston, in August 2008. Two months later, Sir Ian McAllister announced that he would not stand for re-election as chairman of Network Rail after holding the position for six years. He noted that as Network Rail moved to a "new phase in its development" it was appropriate for a new chairman to lead it there. Network Rail also has a 15-year lease on Square One in Manchester with 800 staff in one of Manchester's largest refurbished office spaces. During June 2012, work was completed on the company's new national centre, known as the . Based in Milton Keynes about five minutes' walk from , it comprises four buildings connected to a central street, accommodating more than 3,000 people. Various divisions, including engineering, logistics, operations (including timetable planning), IT, procurement, planning and finance departments, and Route Services Supply Chain operations have been transferred to the Quadrant.
Critical commentary appeared in the media concerning the Knight Bachelor awarded to John Armitt in the 2012 New Year Honours for services to engineering and construction. Armitt was Chief Executive of Network Rail at the time of the 2007 Grayrigg derailment and the family of a victim of the accident criticised the award, which coincidentally was conferred on the same day that Network Rail were prosecuted for the accident.
In 2023, one of Network Rail's managing directors resigned after a litany of problems in the areas she was responsible for. Michelle Handforth resigned after infrastructure problems left hundreds of passengers stranded in carriages in London, one of the latest issues with the lines outside Paddington Station. The Office of Rail and Road was already investigating poor reliability and punctuality in the Wales and Western region.
In December 2016, the Transport Secretary, Chris Grayling announced that Network Rail would lose sole control of track maintenance and repairs, and instead would share this with the Train Operating Companies.
During 2011, work commenced to extend the electrification of the Midland Main Line, including to both Corby and Nottingham. In July 2017, it was announced the then-Secretary of State for Transport Chris Grayling that the electrification scheme north of Kettering to Derby, Nottingham and Sheffield had been cancelled and that bi-mode trains would be used instead. However, in May 2022, a briefing to contractors was released ahead of an invitation to tender for Midland Mainline Electrification project work to extend electrification to Nottingham and Sheffield. This scheme is expected to cost £1.3 billion.
Network Rail has undertaken numerous schemes to develop its own renewable electrical generation footprint, which is used in part to power the operational railway. In January 2014, Network Rail opened the world's largest solar-powered bridge, adjacent to the remains of the old Blackfriars Railway Bridge, across the River Thames. The roof of the new railway bridge is covered with 4,400 photovoltaic panels, providing up to half of the energy requirement for London Blackfriars station. Solar panels are used at various locations across Network Rail's property portfolio, including stations and depots. In August 2022, an agreement between the company and EDF was signed to provide more solar energy.
In July 2025, it was announced that Network Rail's property team would be merged with London and Continental Railways (LCR) to create Platform4, a new state-owned railway property development company. Platform4 was subsequently launched in November 2025.
Network Rail works in five-year funding cycles called "Control Periods" (CP for short). The government specifies what is needed from Network Rail and sets out how much the government can afford to contribute. The Office of Rail and Road (ORR) then sets the level of fixed income that Network Rail is allowed to charge and assesses the amount of money needed by Network Rail to run efficiently. The last Control Period ran from 2014 to 2019; 1 April 2019 was the start of Control Period 6.
In 2019, government funding for train operating companies amounted to £4.1 billion, paying access charges to use the rail network, £2.1 billion and freight £58 million. In 2019, it spent £3.1 billion on renewals (restoring existing infrastructure back to how it was when new) and £3.2 billion on enhancements, with the rest spent on maintenance and other costs.
In February 2004, an operations centre at Waterloo station in London was opened, which was operated jointly by Network Rail and South West Trains. This was the first full collaboration of its kind since privatisation, and it is regarded as a model for other areas of the network, with a further six integrated Network Rail + TOC Control Centres having opened since then, at Blackfriars, Croydon (Leading Control for Thameslink), , , Glasgow and, most recently, Liverpool Street and South Wales based in Cardiff Canton.
Track renewal, the ongoing modernisation of the railway network by replacing track and signalling, continues to be carried out by private engineering firms under contract. The biggest renewals projects include the multibillion-pound upgrade of the London – Glasgow West Coast Main Line, which was completed in 2008, the Thameslink Programme to upgrade the north–south railway through London and work on the part of Crossrail which is operated by Network Rail. A line closure for engineering or renewal works is known as a possession.
Network Rail has an internal infrastructure database known as GEOGIS. The system uses codes for four-digit Track IDs to identify which line at any location is referred to. The first number refers to track direction, with values of 1 (Up), 2 (Down), 3 (Reversible/Bi-directional), or 4 (Merry Go Round Loop). The second number refers to track use, which can be 1 (Main or Fast), 2 (Slow, Local or Relief), 3 (Goods), 4 (Single line), 5 (Loop), 6 (Terminal or Bay), 7 (Crossover), 8 (Other or Engine), or 9 (Single Siding). The third and fourth numbers refer to the track number, which can be any number from 00 to 99 inclusive, and are usually numbered sequentially.
In 2006, Network Rail made public a high-tech plan to combat the effects of slippery rail. This plan involves the use of satellites for tracking trouble areas, water-jetting trains and crews using railhead scrubbers, sand sticks and a substance called Natrusolve, which dissolves leaf mulch.
National
London stations
Glasgow Central and Liverpool Lime Street stations are divided into high and low-level stations – the high-level stations are all termini used primarily by the main inter-city services to those stations. The low-level stations are through routes on local commuter networks that are largely separate from other routes to the main station; these platforms are not managed by Network Rail, but instead by the rail operator that primarily uses them, ScotRail and Merseyrail respectively.
Network Rail operated station until January 2012 when it was transferred to Southern, and until November 2014 when it was transferred to c2c. Network Rail took over management of Bristol Temple Meads and Reading in April 2014.
A DfT franchise report in 2014 stated Network Rail's intention to subsume more major stations into Network Rail's directly operated portfolio. The report earmarked for Network Rail management, as well as Manchester Oxford Road and Manchester Victoria which are currently undergoing major rebuilding as part of the Northern Hub. However the two Manchester stations remained under the operatorship of Arriva Rail North.
There are a small number of stations on the National Rail network that are not owned by Network Rail. As of 2022 these are:
| Peel Ports | |
| Aylesbury Vale Parkway Ltd | |
| West Midlands Combined Authority | |
| Coleshill Parkway Ltd | |
| Earl of Sutherland | |
| HS1 Ltd | |
| Stena Line | |
| Transport for Greater Manchester | |
| Glasgow Prestwick Airport | |
| London Southend Airport | |
| Stena Line | |
| HS1 Ltd | |
| Warwickshire County Council |
In 2008, Network Rail piloted its first qualification in "track engineering". It has been given permission to develop courses equivalent to GCSE and A-levels.
Network Rail operates several analogue radio networks that support mobile communication applications for drivers and lineside workers which consist of base stations, antenna systems and control equipment. The National Radio Network (NRN) was developed specifically for the operational railway; it provides radio coverage for 98% of the rail network through 500 base stations and 21 radio exchanges. The Radio Electronic Token Block RETB system is based on similar technology as the NRN and ORN but provides data communication for signalling token exchange as well as voice communication.
Fixed communication at trackside is provided by telephone. These are primarily provided for signallers to communicate with train crew, via telephones mounted on signal posts, and with the public through telephones located at level crossings. GAI-Tronics provides many of the telephones sited on trackside and at level crossings. They also provide Public Access Help Points on platforms and stations to provide passengers with easy access to Information and Emergency control centres.
GSM-R radio systems are being introduced across Europe under EU legislation for interoperability. In the UK, , Network Rail is well underway in the UK implementation of GSM-R to replace its legacy National Radio Network (NRN) and Cab Secure Radio (CSR) systems currently in use.
Each stage delivers an agreed set of outputs to defined quality criteria. The process has been criticised as cumbersome by some and it is proposed to replace it with a new process with the acronym PACE- Project Acceleration in a Controlled Environment.
The Secretary of State for Transport regularly issues a High-Level Output Specification (HLOS) indicating what work the Government wishes to be undertaken during a given Control Period.
The devolved routes were introduced in 2011, and the 17 strategic routes labelled "A" to "Q" were introduced in 2010. From 2004 to 2009, the network had been divided into 26 strategic routes numbered "1" to "26". In 2003, the network had been divided into 41 strategic routes numbered "1" to "41".
The 2011 devolved routes and strategic routes are organised as in the table below.
Since Network Rail does not have shareholders, its members hold the board of directors to account for their management of the business. From 1 July 2015 all the members were removed leaving the special member, the Secretary of State for Transport, as the sole member of Network Rail.
Previously at any one time there were around 100 members in total, drawn from a wide range of industry partners and members of the public. There were two general categories of membership, industry members comprising any organisation holding a licence to operate on the railway or preferred bidder for a railway franchise, and public members who were drawn from the wider stakeholder community. Members were appointed by an independent panel and served a three-year term. They had a number of statutory rights and duties which included attending annual general meetings, receiving the Annual Report and Accounts, and approving the appointment or re-appointment of Network Rail's directors. Members had a duty to act in the best interests of the company without personal bias. They received no payments other than travel expenses.
Setting the strategic direction and the day-to-day management of Network Rail is the responsibility of the company's board of directors. That direction must be consistent with the regulatory jurisdiction of the ORR, and with the requirements of its contracts. The ORR in turn operates within the overall transport policy set by the UK Department for Transport and the Scottish government, including as to what the government wants the railway industry to achieve and how much money the government is prepared to put into the industry. This means that the degree of government influence and control over the company is higher than it was before these enlargements of the powers and role of the government were introduced by the Railways Act 2005.
The board of Network Rail are:
In the annual report 2014/15, the ORR reported that the Public Performance Measure (PPM) was 89.6%, 1.4 percentage points (pp) below target in England and Wales, and PPM in Scotland was 90.5%, 1.5pp below its regulatory performance target of 92%.
In December 2005, two young girls were killed by a train as they were crossing the railway line via a pedestrian level crossing at in Essex. Network Rail was prosecuted for breaching health and safety law and fined £1million in March 2012. The court heard that risk assessments carried out by Network Rail staff in 2002 had identified potential dangers with the crossing and recommended the installation of gates that would lock automatically as trains approached, but this was not acted upon.
Many track safety initiatives have been introduced in the time Network Rail has been operational. One high-profile measure, announced in December 2008, known as "All Orange", states that all track personnel must not only wear orange hi-vis waistcoats or jackets, but must also wear orange hi-vis trousers at all times when working on or near the track. This ruling came into force in January 2009 for maintenance and property workers and in April 2009 for infrastructure and investment sites.
All workers working on or near the line or trackside have to pass a medical assessment and a drug and alcohol test. They must also sit a Personal Track Safety training course and undergo assessment to be issued with a PTS card (reassessment is required every two years).|format=PDF Network Rail workers undergo periodic assessments as part of the Skills Assessment Scheme, formerly called the AITL process (Assessment in the Line). This requires each worker to go through questions on a computer based program on all the competencies held.
Railtrack plc was placed into railway administration under the Railways Act 1993 on 7 October 2001, following an application to the High Court by the then Transport Secretary, Stephen Byers. It was reported in November 2001 that a further £3.5 billion might be needed to keep the national railway network running, a sum disputed by Ernst & Young, the administrators. To get Railtrack out of administration, the government had to return to the High Court and present evidence that the company was no longer insolvent. The principal reason given by the government to the court for this assertion was the decision of the Rail Regulator in 2002 to carry out an interim review of the company's finances, with the potential to advance significant additional sums to the company. The High Court accepted that the company was not insolvent, and the railway administration order was discharged in October 2002.
Until 2013, there was discussion over whether Network Rail should be classified as a public-sector or a private-sector entity. Although it was officially a private sector organisation, the fact that its debts were underwritten by the government, and it was partly funded by the government, led to the description of "nationalisation in all but name". It was also claimed that the government is keen for Network Rail not to be classified as a public-sector organisation, as this would mean that the company's debt would be counted as public expenditure liabilities. The Office for National Statistics (ONS) repeatedly clashed with the National Audit Office and the Statistics Commission over whether the successor to Railtrack should be considered a private company – as the ONS believed – or included on the Government's books, as the National Audit Office argued. The NAO said that as the Government is bearing the risk that would normally be borne by equity capital, and as it can appoint, through the SRA, a director who cannot be removed by members, Network Rail is effectively a subsidiary of the Government-controlled SRA.
In December 2013, the ONS announced that Network Rail would be classified as a "government body" from September 2014. As a result, the company's debt of £34 billion was added to the national debt. In the 2016–17 financial year, Network Rail's net debt rose from £41.6 billion to £46.3 billion.
Control periods
For financial and other planning purposes, Network Rail works within 5-year "Control Periods", each one beginning on 1 April and ending on 31 March to coincide with the financial reporting year. These periods were inherited from Railtrack, so that the earlier ones are retrospective, and not necessarily of 5 years duration. They are as follows:
Route plans
Network Rail regularly publishes a Strategic Business Plan detailing their policies, processes and plans, as well as financial expenditure and other data. The most recent complete business plan was published in January 2013. Within these plans the rail network is divided into ten “devolved routes” or “operational routes”, with a Route Plan for each being published annually.
Each route or other plan covers a number of railway lines usually defined by geographical area and the routes are further subdivided into 17 “strategic routes”, each divided into Strategic Route Sections (SRS) and given an SRS number and name. The plans also detail the geography of routes, stations, major junctions, capacity constraints and other issues and provide data on freight gauge, electrification, line speed, number of tracks, capacity and other information. The plans also detail the expected future demand and development of each route, their predicted expenditure and their maintenance and investment requirements.

Governance structure and accountability
Formal governance structure
The company is accountable to a body of members through its corporate constitution, to its commercial train operator customers through its contracts with them (the contracts are subject to regulatory oversight), and to the public interest through the statutory powers of the Office of Rail and Road (ORR).
Monitoring Network Rail's performance
The Office of Rail and Road (ORR) monitors Network Rail's performance on a continuous basis against targets established by the regulatory authority in the most recent access charges review (2003), against obligations in the company's network licence and against forecasts in its own business plan. If performance is poor, the company will face criticism and possible enforcement action from its commercial customers (under their contracts) and from the ORR (enforcing the company's network licence). It may also be criticised by its members in general meeting.
Informal governance groups
Railway Industry Planning Group (RIPG)
The Railway Industry Planning Group (RIPG), chaired by Network Rail, has as its purpose railway industry input into the structure and development of the national railway strategic planning processes. Its members are drawn from railway funders, operators and users, and the group meets quarterly to consider:
Safety
While generally good, the safety record of the company was marred in February 2007 when a Virgin express derailed at Grayrigg in Cumbria. Network Rail admitted responsibility for the incident. The RAIB investigation concluded in 2009 that a faulty set of points had caused the derailment. In 2012 the Office of Rail Regulation announced that Network Rail was to be prosecuted under the Health and Safety at Work etc. Act 1974 for "failure to provide and implement suitable and sufficient standards, procedures, guidance, training, tools and resources for the inspection and maintenance of fixed stretcher bar points". Network Rail pleaded guilty and were fined £4.1million including legal costs.
Private versus public-sector status
In 2001, the Labour government denied that it had nationalised the rail network in order to prevent Railtrack's shareholders claiming, via the European Court of Human Rights, the four-year average price of Railtrack, about £10 per share. Instead, Railtrack's shareholders were given only £2.60. The Times reported that Gordon Brown's aide, Shriti Vadera e-mailed Stephen Byers in July 2001 asking: "Can we engineer the solution through insolvency ... and therefore avoid compensation under the Human Rights Act?"
Photography competition
Network Rail organises the Landscape Photographer of the Year competition. Shortlisted photos are displayed at London Waterloo and other major stations.
