A rail operating centre (ROC) is a building that houses all signallers, signalling equipment, ancillaries and operators for a specific region or route on the United Kingdom's main rail network. The ROC supplants the work of several other signal boxes which have thus become redundant.
Network Rail announced the creation of fourteen [1] [2] ROCs situated throughout Great Britain that will control all railway signalling over the British National Rail network. This was subsequently revised to twelve ROCs [3] with responsibilities at two (Saltley and Ashford) being transferred to other ROCs (Rugby and Gillingham respectively). [4]
In November 2016, Network Rail announced that the ROC at Edinburgh would not go into operation with all its functions and responsibilities being transferred to Cowlairs in Glasgow. [5]
Nationally this has meant the redundancy of eight hundred mechanical-lever signal boxes [6] and around two hundred panel and IECC boxes. [7] Some are listed buildings and will be left in situ. [8]
The ROCs are built under private contracts for Network Rail, and will only control the rail routes controlled by Network Rail. Railways in Northern Ireland, various heritage railways and other tramways are not subject to control by a ROC. Ashford IECC still controls the UK stretch of the Channel Tunnel Rail Link (HS1/CTRL), which is owned by London and Continental Railways and not Network Rail. [4]
The ROCs function as signalling and control centres with signalling staff, train operating company (TOC) staff and Network Rail controllers all working under one roof. This is meant to enable quick solutions to signalling problems and fewer delays to trains and passengers. Network Rail envisage the twelve ROCs to be controlling the entire network by 2058. [9]
Originally, the early railways employed 'policemen' to time the intervals between trains and to give a 'stop' signal if a train had passed in the previous ten minutes. [10] Developments led to many everyday workings (such as interlocking points) [11] and signal boxes to house the levers that allowed signallers to change the points and signals over a given stretch of railway. [12] These signalboxes were often elevated above the railway due to the locking mechanisms of the signals and points being accommodated on the lower storey. [13] This also allowed the signaller to keep an eye on things from a good vantage point. [14]
At the end of the Second World War, the United Kingdom network was host to over ten thousand mechanical-lever signalboxes. [15] When British Rail was created from the Big Four private railway companies [16] [17] under the Transport Act 1947, [18] they began to install power signal boxes (PSB) at strategic locations such as Euston, Crewe, Doncaster, Rugby and Carlisle. [19] The PSBs would remove the necessity for many individual boxes along a particular route and would pass control to one centralized location. Carlisle's PSB took over the responsibility of 44 signal boxes alone in the north west area. [20]
A step on from the PSBs was the IECC (Integrated Electronic Control Centre) system, a forerunner of the ROCs. The first IECC panel was installed at London Liverpool Street in 1989. [21]
After the railways in Britain were privatised in 1994, [17] [note 1] [22] staff from the then operating company, Railtrack, paid a visit to the Union Pacific Operating Center, USA in 1999. [23] After viewing the facilities and seeing the control they decided that a small number of major operating centres was the way forward for UK operations. Just one centre was approved and built in 2003 at Saltley, near to Birmingham, as part of the West Coast Route Modernisation. [24] However this building was not connected for some time and whilst it was used by Network Rail staff, no signalling equipment was installed until 2006. [25]
With the advent of the 'Digital Railway' project, [26] signalling methods such as ERTMS have been adopted as a way forward by Network Rail. There are two components of ERTMS, ECTS (European Train Control System) and TMS (Traffic Management System).
Whereas lineside signals operated by a signaller would control train movements, ETCS will signal trains via a computer without lineside apparatus. In effect, the train creates its own 'buffer zone' through a digital signal transmitted from the cab. [27] An onboard computer on the train will inform the driver of the 'allowable speed and movement of the train.' [28] TMS allows delays to be minimised through a computer running algorithms and deciding how best to return traffic patterns to normal.
These systems mean the removal of traditional signalling infrastructure and the signal boxes that go with them.
York IECC (Integrated Electronic Control Centre) is an example of an early version of a ROC. York IECC was opened in 1989 [29] and controlled a large region in Yorkshire bounded by Gargrave, South Emsall, Selby, Northallerton, Cottingley (Leeds), Bramley and the Harrogate loop. [30] [31] The ROC, which opened in York on 12 September 2014, [32] superseded the York IECC in January 2015 [33] and will eventually control the East Coast Main Line and associated lines in Lincolnshire, Yorkshire and the Humber and the North East of England. [34] This means a King's Cross to Edinburgh train will be signalled by York ROC all the way from King's Cross to the Scottish Borders. [35]
Saltley ROC will become a remote signalling centre of Rugby. The facility at Saltley was opened as a bomb-proof [36] signalling centre for the West Coast Route Modernisation. [37] However, the inability to achieve a workable Traffic Management System (TMS) [38] without lineside signalling, meant an increased budget of £1.4 billion [39] and the building became a white elephant. [40] The structure was slowly integrated into a ROC function with signalling upgrades transferring responsibility to Saltley starting in 2006. [41] Because the interlocking mechanisms are in place, they will be left at Saltley and operated remotely from the Rugby ROC. What Saltley cannot do, that Rugby can, is host the human space needed for the signallers and train operating company (TOC) staff to work together. [25]

In 2011, Network Rail forecast that 40% of the then remaining 845 signal boxes would be closed by 2017. Progress on this has been slower than anticipated and, by the end of 2017, 137 signal boxes that were due to close were still open. [45]
Whilst the drive for the ROCs has been one of signalling upgrades, there are other benefits and detractions to the scheme. Around four thousand staff will lose their jobs over the course of the implementation programme leaving two thousand signallers in the ROCs. [66] The benefits of centralised control will be that the train operating company (TOC) staff will work alongside the Network Rail staff to allow cohesive problem solving such as resolving late running and last-minute platform changes. Network Rail have said that "The ROC is a key part of our strategy to improve reliability whilst driving down the cost of running and maintaining the railway." [67]
In 2016, it came to light that Network Rail had been hacked four times up to July 2016. As most of the rail network in the United Kingdom is analogue, it would not affect anything, but Network Rail have an aspiration for the digital rail Traffic Management System to go live in 2018. An online security company, who were not commissioned by, or working for Network Rail, discovered the hacks and declared that whilst the hacks were "probing and not disruptive," they could well be full of malicious software in the future. [68]
Network Rail responded by saying that
"Britain has the safest major railway in Europe... safety is our top priority, which is why we work closely with government, the security services, our partners and suppliers in the rail industry and security specialists to combat cyber threats." [69]
In 2017, Ian Prosser, the chief inspector of railways informed the Transport Select Committee that not enough had been done to alleviate the possibility of the ROCs becoming a single point of failure. Prosser highlighted higher workload on signallers and the contingencies needed in the event of a natural disaster disabling one of the ROCs. [70]
ROCs are mostly referred to as rail operating centres. [71] Even in Network Rail's own documentation they are sometimes referred to as railway operating centres. [72] Some of the railway press have referred to them as route operating centres [73] [note 5] and even regional operating centre. [74] [75]
This issue is further clouded by Network Rail having another ROC, the Railway Operational Code [76] and the signalling industry in the United Kingdom having a Remote Override Control. [77]
The Northern City Line is a commuter railway line in England, which runs from Moorgate station to Finsbury Park in London with services running beyond. It is part of the Great Northern Route services, and operates as the south-eastern branch of the East Coast Main Line (ECML). It is underground from Moorgate to Drayton Park in Highbury, from which point it runs in a cutting until joining the ECML south of Finsbury Park. Its stations span northern inner districts of Greater London southwards to the City of London, the UK's main financial centre. Since December 2015, its service timetable has been extended to run into the late evenings and at weekends, meeting a new franchise commitment for a minimum of six trains per hour until 23:59 on weekdays and four trains per hour at weekends.
The East Coast Main Line (ECML) is a 393-mile long (632 km) electrified railway between its southern terminus at London King's Cross station and Edinburgh Waverley via Peterborough, Doncaster, York, Darlington, Durham and Newcastle. The line is a key transport artery on the eastern side of Great Britain running broadly parallel to the A1 road. The main line acts as a 'spine' for several diverging branches, serving destinations such as Cambridge, Leeds, Hull, Sunderland and Lincoln, all with direct services to London. In addition, a few ECML services extend beyond Edinburgh to serve Glasgow Central, although the principal London-Glasgow route is the West Coast Main Line (WCML).
York railway station is on the East Coast Main Line serving the cathedral city of York, North Yorkshire, England. It is 188 miles 40 chains (303.4 km) north of London King's Cross and on the main line it is situated between Doncaster to the south and Thirsk to the north. As of June 2018, the station is operated by London North Eastern Railway. It is the busiest station in North Yorkshire, the second busiest in Yorkshire & the Humber, and the fifth busiest in Northern England.
Radio Electronic Token Block is a system of railway signalling used in the United Kingdom. It is a development of the physical token system for controlling traffic on single lines. The system is slightly similar to North American direct traffic control, which unlike RETB does not have a cab display unit.
The Cambrian Line, sometimes split into the Cambrian Main Line and Cambrian Coast Line for its branches, is a railway line that runs from Shrewsbury, England, westwards to Aberystwyth and Pwllheli in Wales. Passenger train services are operated by Transport for Wales Rail between the western terminals of Pwllheli, in Gwynedd, and Aberystwyth, in Ceredigion, and the eastern terminal at Shrewsbury, Shropshire, as part of the Wales & Borders franchise. The railway line is widely regarded as scenic, as it passes through the Cambrian Mountains in central Wales, and along the coast of Cardigan Bay in Snowdonia National Park.
Brimsdown railway station is on the West Anglia Main Line, serving the neighbourhood of Brimsdown in the London Borough of Enfield, north London. It is 10 miles 61 chains (17.3 km) down the line from Liverpool Street and is situated between Ponders End and Enfield Lock. Its three-letter station code is BMD and it is in Travelcard zone 5.
The European Train Control System (ETCS) is a train protection system designed to replace the many incompatible systems used by European railways, and railways outside of Europe. ETCS is the signalling and control component of the European Rail Traffic Management System (ERTMS).
The Integrated Electronic Control Centre (IECC) was developed in the late 1980s by the British Rail Research Division for UK-based railway signalling centres, although variations exist around the world. It is the most widely deployed VDU based signalling control system in the UK, with over 50 workstations in control centres that manage many of the most complex and busy areas of the network.
Thirsk railway station is on the East Coast Main Line and serves the market town of Thirsk, North Yorkshire, England. It is situated between York to the south and Northallerton to the north. Its three-letter station code is THI. The station is about 2 miles (3 km) outside of Thirsk town centre and is actually on the edge of the village of Carlton Miniott.
The Peterborough–Lincoln line is a railway line linking Peterborough and Lincoln Central, via Sleaford and Spalding. Between Lincoln and Spalding, the line follows the route of the former Great Northern and Great Eastern Joint Railway.
SimSig is a mixed donationware and commercial Windows-based train simulator of modern railway signalling systems in Great Britain, from the point of view of a railway signaller. Users have also had success running SimSig on Linux using Wine.
Glaisdale is a railway station on the Esk Valley Line, which runs between Middlesbrough and Whitby via Nunthorpe. The station, situated 9 miles 33 chains (15.1 km) west of Whitby, serves the village of Glaisdale in North Yorkshire, England. It is owned by Network Rail and managed by Northern Trains.
Resonate Group Limited is a British software, technology and services company. Prior to September 2016, it was called DeltaRail Group Limited.
The European Rail Traffic Management System (ERTMS) is the system of standards for management and interoperation of signalling for railways by the European Union (EU). It is conducted by the European Union Agency for Railways (ERA) and is the organisational umbrella for the separately managed parts of
Wrawby Junction is a busy railway junction located a short distance west of Barnetby, North Lincolnshire, England and controls the confluence of the Network Rail routes from Lincoln, Retford and Scunthorpe towards Immingham and Cleethorpes. The junction was controlled by a large signal box of part-brick, part-wooden, construction and is now controlled from York Rail Operating Centre (ROC).
London Bridge Area Signalling Centre (ASC) was a signalling centre on the Kent Route of Network Rail, principally covering the line from London to Kent and Sussex route areas of Network Rail. The signalling centre was opened in 1974, and closed in 2020.
York Integrated Electronic Control Centre was a major signalling control centre on the East Coast Main Line railway between London and Edinburgh. The centre also contained the electrical control centre for the line and the LNE regional control office of Network Rail. Its responsibility for signalling across Yorkshire was transferred to York Rail Operating Centre in December 2018.
The Selby Line is a secondary railway line in Yorkshire, England, linking Leeds to Selby via Micklefield, and then on to Kingston upon Hull (Hull). Hull Trains, London North Eastern Railway, Northern and TransPennine Express operate passenger trains on the line.
On 3 February 2003, a Comeng electric multiple unit train rolled away from Broadmeadows station in Melbourne, Australia, before it ran for nearly 17 kilometres (11 mi) out of control without a driver and eventually crashed into another train about to depart Spencer Street station. Train controllers attempted several times to stop or redirect the train, but were limited in their ability to intervene, instead being forced to alter the route of other trains to avert a more serious collision. Eleven people on board the stationary train were injured; authorities did not know until after the crash if any passengers were on board the runaway. An investigation identified driver error as the cause of the accident, but the runaway event prompted significant debate about the role of government authorities and private operators in ensuring safety and reliability on the Melbourne rail network.
York Rail Operating Centre is a Rail operating centre (ROC) located at the south western end of York railway station in York, England. The site is one of twelve that will control all signalling across the mainland of the United Kingdom. It was opened in stages from 2014 onwards, with responsibility for signalling becoming active in January 2015. The York ROC accepted the role of its predecessor, the adjacent York Integrated Electronic Control Centre (IECC), in December 2018.
