Network Rail is the owner (via its subsidiary Network Rail Infrastructure Ltd, which was known as Railtrack plc before 2002) and infrastructure manager of most of the railway network in Great Britain. Network Rail is an arm's length public body of the Department for Transport with no shareholders, which reinvests its income in the railways.
Network Rail's main customers are the private 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 quickly rising passenger numbers, Network Rail is currently undertaking a £38 billion programme of upgrades to the network, including Crossrail, electrification of lines and upgrading Thameslink.
Britain's railway system was built by private companies, but it was nationalised by the Transport Act 1947 and run by British Railways until re-privatisation which was begun in 1994 and completed in 1997. Infrastructure, passenger and freight services were separated at that time. Between 1994 and 2002 the infrastructure was owned and operated by Railtrack.
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 £580 million 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, which all but brought the railway network to a standstill. The costs of modernising the West Coast Main Line were also spiralling. In 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 then used to pay a £137m dividend to its shareholders in May 2001.
Network Rail Ltd took over control by buying Railtrack plc, which was in "railway administration", from Railtrack Group plc for £500 million; Railtrack plc was then renamed and reconstituted as Network Rail Infrastructure Ltd. The purchase was completed on 3 October 2002. The former company had thus never ceased to exist but continued under another name: for this reason Network Rail Infrastructure Ltd was the defendant in later prosecutions in respect of events which had occurred in the days of Railtrack.
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.
The company moved its headquarters to Kings Place, 90 York Way, from 40 Melton Street, Euston, in August 2008. In October 2008, Sir Ian McAllister announced that he would not stand for re-election as chairman of Network Rail. He had held 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.
Many track safety initiatives have been introduced in the time Network Rail has been responsible for this area. The latest, 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.
In 2009, allegations appeared in the media from the Transport Salaried Staffs' Association concerning treatment of Network Rail employees. Former chief executive Iain Coucher was also accused of financial impropriety involving unspecified payments to his business partner Victoria Pender during his tenure at Network Rail.
An internal investigation held by Network Rail in 2010, vetted by its auditors PricewaterhouseCoopers, uncovered no evidence of wrongdoing. An independent enquiry headed by Anthony White QC in 2011 further examined the claims, but also exonerated Coucher.
Critical commentary appeared in the media concerning the knighthood 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 2011 the company began the process of reorganising its operational structure into nine semi-autonomous regional entities, each with their own managing director; the first two units to be created were Scotland and Wessex regions. The reorganisation has been interpreted as a move back towards vertical integration of track and train operations.
In 2016 Network Rail failed to check whether the Flying Scotsman could fit through tunnels along the Borders Route resulting in the cancellation of a trip just 24 hours before departure. The operator described the cancellation as "an absolute disgrace", Network Rail blamed the cancellation on an internal "administrative error". Just one day later Network Rail chose to change their mind and allow the train journey to take place. Scottish Transport Minister Derek Mackay branded the affair a "debacle".
Network Rail's attempt to electrify the Great Western Main Line has been dogged by poor planning and cost overruns. The projected cost had increased from £1.2 billion to £2.8 billion by the end of 2015 and the project has been delayed to the point where the government has asked Hitachi to retrofit the new Intercity Express Programme trainsets with diesel as well as electric engines as the electrification has been scaled back.
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.
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. It however owns a fleet of departmental stock.
Although it owns over 2,500 railway stations, it manages only 20 of the biggest and busiest of them, all the other stations being managed by one or other of the various train operating companies (TOCs). Network Rail has a 15-year lease on Square One in Manchester with 800 staff in one of Manchester's largest refurbished office spaces.
Network Rail should not be confused with 'National Rail'. National Rail is not an organisation, but merely a brand, used to explain and promote a Great Britain-wide 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 (for example High Speed 1, Heathrow Express, Tyne and Wear Metro (the Tyne and Wear Metro uses Network Rail track between Pelaw and Sunderland and is responsible for that) and the London Underground). Conversely, a few National Rail services operate over track which is not part of the Network Rail network. For example, Chiltern Railways services run on track owned by London Underground between Harrow-on-the-Hill and Amersham.
Network Rail is a Not for dividend organisation. The majority of funding comes from a mix of direct grants and borrowing from the UK and Scottish Governments, payments from train and freight operators and a small amount of income from commercial property estate.
Network Rail works in funding cycles of 5 years called "Control Periods" or "CP" for short. The government specify what they need from NR plus setting out how much they can afford to contribute, the ORR then sets the level of fixed income Network Rail are allowed to charge and assess the amount of money Network Rail need to run efficiently. The last Control Period ran from 2014-2019, the 1st April 2019 was the start of Control Period (CP) 6.
In 2019 funding from the government amounted to £4.1 billion with train operating companies, paying access charges to use the rail network, £2.1 billion and freight £58 million. In 2019, it spent £3.1 billion on renewals (renewing existing infrastructure back to how it was when new) and £3.2 billion on enhancements, with the rest spent on maintenance and other costs.
Network Rail covers 20,000 miles of track, and 40,000 bridges and tunnels.
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.
February 2004 saw the opening of an operations centre at Waterloo station in London, 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), Swindon, Birmingham New Street, 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.
Network Rail initially sub-contracted much of the work and the site to private infrastructure maintenance companies such as Carillion and First Engineering. Other sub-contractors are used on site for specialist work or additional labour. These include Prima Services Group, Sky Blue, Balfour Beatty, Laboursite, BCL, Atkins (Atkins Rail) and McGinleys.
Since 2003 Network Rail has been building up significant in-house engineering skills, including funding of apprenticeship and foundation degree schemes. Network Rail reports significant savings resulting from the initial transfers of work away from contracting companies. Additional contracts were taken back by Network Rail after the serious accident at Potters Bar and other accidents at Rotherham and King's Cross led Jarvis to pull out of the track repair business. Shortly after this, and due to other failures by maintenance companies, Network Rail took control of many more maintenance duties. Telecomms maintenance came full circle in April 2009 with the bringing in house of the staff of Thales Telecom Services Ltd (formerly British Rail Telecommunications (BRT)).
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.
All workers working on, near or trackside have to undergo a Personal Track Safety assessment (re-assessed every two years). Network Rail workers undergo an assessment every year as part of AITL (Assessment in the Line). The AITL requires each worker to go through questions on a computer based program on all the competencies held.
A line closure for engineering or renewal works is known as a possession.
In 2007 it was announced that the number of track renewal contractors will be reduced to four from the current six. These are now Amey/SECO, Balfour Beatty, Babcock First Engineering and Jarvis plc. Jarvis went into administration in March 2010, with the bulk of its work commitments being picked up by Babcock.
Network Rail owns more than 2,500 railway stations, divided into six categories. Management and operation of most of them is carried out mostly by the principal train operating company serving that station; however, in a few cases the train operating company does not serve the station. For example, Hinckley is served by CrossCountry, but it is managed by East Midlands Railway. As of April 2018, Network Rail manages 20 stations directly, with Clapham Junction and Guildford becoming managed stations on 1 April 2018. The stations Network Rail operate are:
Central London stations
Network Rail High Speed also operates the non-international areas of London St Pancras International High Level, Stratford International and Ebbsfleet International. 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 the rail operator that primarily uses them (Abellio ScotRail and Merseyrail respectively).
Network Rail operated Gatwick Airport station until January 2012 when it was transferred to Southern, and Fenchurch Street 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 York 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 as of September 2017 the two Manchester stations remain under the operatorship of Northern.
Network Rail has several training and development sites around Britain. These include sites in York, Peterborough, Derby, Leeds, Walsall and Larbert which provide refresher courses, and train staff in new equipment. Advanced Apprentice Scheme trainees are trained at Network Rail's Westwood training centre for the first five months of their apprenticeship and then are trained further at HMS Sultan in Gosport over seven 2-week periods or five 3-week periods (throughout their second and third year) of their apprenticeship, using a combination of Royal Navy facilities and a specially installed training centre. All courses are taught by VT Flagship (part of Babcock International) in the first year but apprentices are trained by Network Rail staff in the second and third years. Network Rail bought a residential centre from Cable and Wireless in the Westwood Business Centre near Coventry for leadership development. The company and other industry partners such as VolkerRail and Balfour Beatty also operate a Foundation Degree in conjunction with Sheffield Hallam University.
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 various essential telecommunication circuits for signalling and electrification control systems, train radio systems, lineside communications, level crossing CCTV, station information and security systems as well as more general IT and business telephony needs. The fixed bearer network infrastructure comprises transmission systems and telephone exchanges linked by a fibre optic and copper cable network that is located mainly within trackside troughing routes on the former British Rail Telecommunications network. (It is the largest private telecoms network in the UK).
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, as of March 2014, 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.
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.
Network Rail operates a large variety of DMUs, locomotives and rolling stock to perform safety checks and maintenance (this fleet is not to be confused with the combined rolling stock assets of ATOC members who work in combination as National Rail). As well as the multiple units and locomotives detailed below, Network Rail own and operate a large stock of rolling stock for particular testing duties and track maintenance. Network Rail also hire freight locomotives from various freight operators including DB Cargo UK, Freightliner, Colas Rail and GB Railfreight amongst others to operate engineers' trains in support of maintenance and renewal work. Network Rail's Infrastructure Monitoring fleet of test trains is operated by Colas Rail, primarily using locomotives from Colas' and Network Rail's own fleets, but also using locomotives hired from other companies such as Direct Rail Services, GB Railfreight and Europhoenix as required.

From 1997 to 2014 (inclusive), passenger numbers have more than doubled, following little growth in the previous decades. To cope with the increasing passenger numbers, Network Rail is currently undertaking a £38 billion programme of upgrades to the network, including Crossrail, electrification of lines, in-cab signalling, new inter-city trains, upgrading Thameslink, and a new high-speed line.
For investment projects, as opposed to routine maintenance, Network Rail has developed an eight-stage process designed to minimise and mitigate risks. This is known as the Governance for Railway Investment Projects (GRIP), previously known as "Guide to Rail Investment Projects". The stages are as follows:
Each stage delivers an agreed set of outputs to defined quality criteria.
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:
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.
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.
|Devolved Route||Strategic Route||Primary routes||Other destinations||Former strategic routes 2004-09|

Network Rail opened the world's largest solar-powered bridge at Blackfriars Bridge across the River Thames in January 2014. The roof of the bridge has been covered with 4,400 photovoltaic panels, providing up to half of the energy for London Blackfriars station.
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).
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 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.
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%.
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:
Previous chief executives
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 Act 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 £4.1 million including legal costs.
In December 2005 two young girls were killed by a train as they were crossing the railway line via a pedestrian level crossing at Elsenham in Essex. Network Rail was prosecuted for breaching health and safety law and fined £1 million 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.
In 2001 the then 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?"
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 go back 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 is 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 is partly funded by the government, has led to its being described as being "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 from September 2014 Network Rail will be classified as a "government body". This resulted in the company's debt of £34 billion being 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.
The new national centre now known as 'The Quadrant:MK' is in Milton Keynes: it completed construction in June 2012. The complex is five minutes' walk from Milton Keynes Central. The four buildings, which are connected to a central street, accommodate about 3,000 people. As of June 2012 , the engineering, logistics, operations including timetable planning, IT, procurement, planning and finance departments all planned to move to the Quadrant.
