East Coast Main Line
The East Coast Main Line (ECML) is a 393-mile (632 km) long high-speed railway link between London, Peterborough, Doncaster, Wakefield, Leeds, York, Darlington, Newcastle, Edinburgh and Aberdeen, electrified between London and Edinburgh; sections north of Edinburgh being serviced by diesel trains. It is classed as a high-speed railway because most of it meets the speed criterion of 125 mph (201 km/h). The main franchise on the line is operated by state-owned East Coast Main Line Company Ltd.
The route forms a key artery on the eastern side of Great Britain and is broadly paralleled by the A1 trunk road. It links London, the South East and East Anglia with Yorkshire, the North East Regions and Scotland. It also carries key commuter flows for the north side of London. It is therefore important to the economic health of several areas of England and Scotland. It also handles cross-country, commuter and local passenger services, and carries heavy tonnages of freight traffic. The route has ELRs ECM1 - ECM9.
Route definition and description
- The main line between London King's Cross and Edinburgh Waverley stations, via Stevenage, Peterborough, Grantham, Newark North Gate, Retford, Doncaster, York, Darlington, Durham, Newcastle, Berwick-upon-Tweed and Dunbar;
- The Doncaster branch of the Wakefield Line, between Doncaster and Leeds, via Wakefield Westgate;
- The Northern City Line from Finsbury Park to Moorgate; and
- The Hertford Loop Line from Alexandra Palace to Stevenage.
The core part of the route is the main line between King's Cross and Edinburgh, with the Hertford Loop used for local and freight services and the Northern City Line only used on weekdays for inner suburban services.
In addition to the formal Network Rail definition, the ECML is generally regarded as including the Edinburgh to Aberdeen Line, on which through express trains have run since before the 1923 creation of LNER and LMS. Some East Coast services continue beyond Edinburgh Waverley to Aberdeen, using the diesel engined HST originally built to serve the line, replacing the Deltic diesels which in turn (1962) replaced the LNER A4 Pacific express steam locomotives.[dubious ] running mostly in view of the east coast via Kirkcaldy, Dundee and Arbroath.[dubious ]| North of Edinburgh it includes the red cantilever Forth Bridge, and at Dundee the curved Tay Bridge, both crossing wide river estuaries.[dubious ]
The line was built by three railway companies, each serving their own area but with the intention of linking up to form the through route that became the East Coast Main Line. From north to south they were
- the North British Railway, from Edinburgh to Berwick-on-Tweed, completed in 1846,
- the North Eastern Railway from Berwick-on-Tweed to Shaftholme
- the Great Northern Railway from Shaftholme to Kings Cross, completed in 1850.
When first completed, the GNR made an end-on connection at Askern famously described by the GNR's chairman as "a ploughed field four miles north of Doncaster" with the Lancashire and Yorkshire Railway, a short section of which was used to reach the NER at Knottingley. In 1871 the NER combined an existing York - Selby line with a new section south of Selby to form a direct through route to an end-on junction with the GNR, at Shaftholme, just south of Askern.
Realising that through journeys were an important part of their business, the companies established special rolling stock in 1860 on a collaborative basis; it was called the "East Coast Joint Stock".
Numerous alterations to short sections of the original route have taken place, the most notable being the opening of the King Edward VII Bridge in Newcastle upon Tyne in 1906 and the Selby diversion, built to by-pass anticipated mining subsidence from the Selby coalfield and a bottleneck at Selby station. The Selby diversion was opened in 1983 and diverged from the original ECML at Temple Hirst, north of Doncaster, and joined the Leeds to York line at Colton Junction.
The northernmost section from Kinnaber Junction, north of Montrose to Aberdeen was built by the Caledonian Railway, but with North British running rights to Aberdeen Station, commonly referred to as Aberdeen Joint Station. The 'Race to the North' from London to Aberdeen was effectively resolved by the shortening of the King's Cross route by the construction of the two bridges, crossing the Forth and Tay estuaries.
The ECML has been the backdrop for a number of famous rail journeys and locomotives. The line was worked for many years by Pacific locomotives designed by Gresley, including the famous steam locomotives "Flying Scotsman" and "Mallard". Mallard achieved a world record speed for a steam locomotive, at 126 miles per hour (203 km/h) and this record was never beaten. It made the run on the Grantham-to-Peterborough section, on the descent of Stoke Bank.
Steam locomotives were replaced by Diesel electrics in the early 1960s, when the purpose-built Deltic locomotive was developed by English Electric. The prototype was successful and a fleet of 22 locomotives was built, to handle all the important express traffic. The Class 55 were powered by two engines originally developed for fast torpedo boat purposes, and the configuration of the engines led to the Deltic name. Their characteristic throaty exhaust roar and chubby body outline made them unmistakable in service. The class 55 was for a time the most powerful diesel locomotive in service in Britain, at 3,300 hp (2,500 kW).
It was just after the Deltics were introduced that the first sections of the East Coast Main Line were upgraded to officially allow 100 miles per hour (160 km/h) running. The first length to be cleared for the new higher speed was a 17 miles (27 km) stretch between Peterborough and Grantham on 15 June 1965, the second was 12 miles (19 km) between Grantham and Newark.
As the demand for higher speed intensified, the Deltics were eventually superseded by the High Speed Train (HST), introduced between 1976 and 1981 and still in service in 2013 (re-engined, with the original Paxman Valenta power units replaced by MTU engines).
A prototype of the HST, the Class 41 achieved 143 mph (230 km/h) on the line in 1973. Current UK legislation requires in-cab signalling for speeds of over 125 mph which is the primary reason preventing the InterCity 225 train-sets from operating at their design speed of 140 mph (225 km/h) in normal service.
A secondary factor was that the signalling technology of the time was insufficiently advanced to allow detection of two broken rails on the line on which the train was operating.
Before the present in-cab regulations came in, British Rail experimented with 140 mph running by introducing a fifth, flashing green signalling aspect on track between New England North and Stoke Tunnel. The fifth aspect is still shown in normal service and appears when the next signal is showing a green (or another flashing green) aspect and the signal section is clear which ensures that there is sufficient braking distance to bring a train to a stand from 140 mph. Locomotives have operated on the ECML at speeds of up to 161.7 mph (260.2 km/h) in test runs.
Electrification of the ECML was authorised in 1984, and work began in 1985 with the initial section between King's Cross and Leeds going into operational trials in 1988. Electrification as far as Edinburgh was completed in late 1990, and the current InterCity 225 rolling stock was introduced.
The line is mainly four tracks from London to Stoke Tunnel, south of Grantham, except for two twin-track sections; the first of these is near Welwyn North Station as it crosses the Digswell Viaduct and passes through two tunnels, the second is between Huntingdon and Peterborough near 'Stilton Fen'. North of Grantham the route is twin track except for four-track sections at Retford around Doncaster, between Colton Junction (which is south of York), Thirsk and Northallerton, and another at Newcastle.
With most the of the line rated for 125 mph (200 km/h) operation, the ECML was the fastest main line in the UK until the opening of High Speed 1. These relatively high speeds are possible because much of the ECML travels on fairly straight track on the flatter, eastern regions of England, through Lincolnshire and Cambridgeshire, though there are significant speed restrictions (due to curvature) particularly North of Darlington and between Doncaster and Leeds. By contrast, the West Coast Main Line has to traverse the Trent Valley and the mountains of Cumbria, leading to many more curves and a lower general speed limit of 110 mph (180 km/h). Speeds on the WCML have been increased in recent years with the introduction of tilting Pendolino trains and now match the 125 mph speeds available on the ECML.
Most passenger services use the InterCity 225 rolling stock. Some diesels still operate on line, including:
- CrossCountry's Class 220 Voyagers, Class 221 Super Voyagers and, occasionally, HST sets that CrossCountry introduced after it took over from Virgin CrossCountry. (Joining the ECML at York and continuing to Newcastle, Edinburgh, Glasgow, Dundee and Aberdeen)
- First Hull Trains Class 180 Adelantes (Kings Cross–Hull)
- East Coast HST sets work some services to Leeds, Newcastle and Edinburgh, and all services that continue north of Edinburgh to Inverness and Aberdeen, as well as daily services to Lincoln, Hull, Skipton and Harrogate .
- East Midlands Trains operates a limited service of HSTs over a portion of the route between Doncaster and Leeds, and a summer Saturday service with Class 222 Meridians from Doncaster and Scarborough to London St Pancras, and back.
- Grand Central's HSTs and Class 180 Zephyrs (Kings Cross–Sunderland/Bradford)
The line's current principal operator is East Coast, whose services include regular trains between King’s Cross, the East Midlands, Yorkshire, the North East of England and Scotland. East Coast is subsidiary of Directly Operated Railways—a holding company owned by the Department for Transport—and took over from National Express East Coast on 14 November 2009. Other operators of passenger trains on the line are:
- First Capital Connect: commuter services between King's Cross, Peterborough, Cambridge and King's Lynn and between Moorgate and Stevenage via either Welwyn Garden City or the Hertford Loop.
- First Hull Trains: between Kings Cross and Hull.
- East Midlands Trains: local services between Grantham and Peterborough, part of the service that runs between Liverpool Lime Street and Norwich, as well as London services between Doncaster and York/Scarborough, extensions of services running to/from Sheffield, Leicester and London St Pancras.
- CrossCountry: cross-country services north of Sheffield are routed via either Leeds or Doncaster. Leeds trains use the ECML between Wakefield Westgate and Leeds and then again north of York. Doncaster trains use the ECML north of Doncaster. Services run to and beyond Edinburgh. Occasional services run from Doncaster to Leeds before rejoining the ECML at York.
- First TransPennine Express: between York and Newcastle and between York and Northallerton before they divert off the ECML to Middlesbrough via Yarm.
- Northern Rail: suburban services from Doncaster to Leeds and Chathill to Newcastle via Morpeth railway station and infrequent services between Newcastle and Darlington that continue to Middlesbrough and Saltburn. Services between Selby and York also use the line from Hambleton Junction to York.
- First ScotRail: services from Edinburgh Waverley to North Berwick and Dunbar. The overnight Caledonian Sleeper occasionally uses the ECML when engineering works prevent it from using its normal train path on the WCML.
- Grand Central: intercity from Kings Cross to Sunderland, branching off the main line at Northallerton and Bradford, branching off at Doncaster.
Eurostar previously held the rights to run five trains a day on the line for services from continental Europe to cities north of London, as part of the Regional Eurostar plan, although such services have never been run.
The ECML is one of the busiest lines on the British rail network and there is currently insufficient capacity on parts of the line to satisfy all the requirements of both passenger and freight operators.
There are bottlenecks at the following locations:
- The section of twin track within a four-line section at Welwyn North over the Digswell Viaduct and through the Welwyn tunnels
- Just north of Newark station at a flat crossing with the Nottingham-Lincoln line.
- Doncaster station has limited facilities for terminating branch trains on the up side of the station.
- South of Newcastle, leading to proposals to reopen the Leamside line to passenger and freight traffic.
Rail services are vulnerable during high winds and there have been several de-wirements over the years due to the unusually wide spacing between the supporting masts of the overhead lines. The other cost-cutting measure was the use of headspan-type catenary systems over the quadruple tracked sections which are not as robust as the older gantry-type design used on the WCML. This was a result of extreme pressure from the Department for Transport (as proxy for the taxpayer) to reduce avoidable costs when the line was originally electrified between 1985 and 1990.
- The Allington Chord was constructed near Grantham in 2006, allowing services between Nottingham and Skegness to call at Grantham without having to use the ECML, trains now passing under the line. This provided sufficient extra capacity for National Express East Coast to run 12 additional services between Leeds and London each day.
- A new platform at London Kings Cross was opened on 20 May 2010. This was originally to be called "Platform Y". Instead it was named platform 0 to avoid confusion of lettered and numbered platforms. The platform will be renamed platform 1 after major restoration work to the station is complete.
- The southern side of York station was given new track and signalling systems. An additional line (a fourth track at Holgate Junction) and new junction were completed in early 2011. This work helped to remove one of the bottlenecks on the East Coast Main Line. Previously, trains would sometimes have to wait before entering the station. The improvements allow for better flow of trains in and out of the station.
- Provision of a grade-separated junction to the north of Hitchin (the Hitchin flyover) enabling down Cambridge trains to cross the main line The work was completed by 26 June 2013
Over the years successive infrastructure managers have developed schemes for route improvements.
These include the following:
- Linking the ECML to Thameslink as part of the Thameslink Programme (for First Capital Connect commuter services to be extended to south London).
- Quadrupling the Welwyn North section, involving probable double-decking of the viaduct and duplication of the two tunnels
- Full reversible signalling over the Stilton Fen section
- Power supply upgrades along the route, including some OLE support improvements and rewiring
- Power supply enhancement on the diversionary Hertford Loop route
- Provision of a new Up bay platform at Doncaster station
- Enhanced passenger access to the platforms at Peterborough and Stevenage
- Increasing maximum speeds on the fast lines to between 125 mph and 140 mph in conjunction with the introduction of the Intercity Express Programme
- Replacement of the Newark North Gate Flat Crossing with a flyover
- Major remodelling of Peterborough station
- A new flyover at Shaftholme Junction in South Yorkshire, near the former Joan Croft station, to allow freight trains from Immingham to pass over the line on their way to Eggborough and Drax power stations, due for completion by the end of 2013
- Reopening of freight diversionary routes
- The line section between London King's Cross to the approach of Doncaster will be signaled with Level 2 ERTMS. The target date for operational ERTMS services is December 2018 with completion in 2020
- An £8.6 million redevelopment of Newcastle Central Station will be undertaken enhancing the existing station and provide a state-of-the-art station for thousands of passengers.

The cuttings and tunnel entrances just north of King's Cross make a memorable smoky appearance in the 1955 Ealing comedy film The Ladykillers. Also during the 1950s, the line featured in the 1954 documentary short Elizabethan Express. Later, the 1971 British gangster film Get Carter features a journey from London Kings Cross to Newcastle in the opening credits. The motoring show Top Gear featured a race including LNER A1 60163 Tornado running up this line from London to Edinburgh.
