East Coast Main Line


The East Coast Main Line is a electrified railway between London and Edinburgh 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 line was built during the 1840s by three railway companies, the North British Railway, the North Eastern Railway, and the Great Northern Railway. In 1923, the Railway Act of 1921 led to their amalgamation to form the London and North Eastern Railway and the line became its primary route. The LNER competed with the London, Midland and Scottish Railway for long-distance passenger traffic between London and Scotland. The LNER's chief engineer Sir Nigel Gresley designed iconic Pacific steam locomotives, including the "Flying Scotsman" and "Mallard" which achieved a world record speed for a steam locomotive, on the Grantham-to-Peterborough section.
On 1 January 1948, the railways were nationalised and operated by British Railways. In the early 1960s, steam was replaced by Diesel-electric traction, including the Deltics and sections of the line were upgraded so that trains could run at speeds of up to. With the demand for higher speed, British Rail introduced InterCity 125 high-speed trains between 1976 and 1981. In 1973, the prototype of the HST, the Class 41, achieved a top speed of in a test run. In the 1980s, the line was electrified and InterCity 225 trains were introduced.
The line links London, South East England and East Anglia, with Yorkshire, the North East and Scotland and is important to their local economies. It carries key commuter traffic in north London and cross-country, commuter, local passenger services, and freight. Services north of Edinburgh to Aberdeen and Inverness use diesel trains. In 1997, operations were privatised. It is operated by London North Eastern Railway which took over from Virgin Trains East Coast in June 2018.

Route definition and description

The ECML is part of Network Rail's Strategic Route G which comprises six separate lines:
The core route is the main line between King's Cross and Edinburgh, the Hertford Loop is used for local and freight services and the Northern City Line provides an inner suburban service to the city. The line has ELRs ECM1 - ECM9.

Origins and early operations

The ECML was constructed by three independent railway companies. During the 1830s and 1840s, each company built part of the route to serve its own area, but also intending to link with other railways to form the through route that would become the East Coast Main Line. From north to south, the companies were:
The GNR established an end-on connection with the NER at Askern, famously described by the GNR's chairman as in "a ploughed field four miles north of Doncaster". Askern was connected to the Lancashire and Yorkshire Railway, a short section of which was used to reach the NER at Knottingley. In 1871, the line was shortened when the NER opened a direct line from an end-on junction, with the GNR, at Shaftholme, just south of Askern to Selby and over Selby Bridge on the Leeds-Hull line direct to York.
Through journeys were important and lucrative for the companies and in 1860 they built special rolling stock for the line. Services were operated using "East Coast Joint Stock" until 1922.
In 1923, in an effort to stem the losses of smaller companies, the Railway Act of 1921 required the companies to amalgamate to form the London and North Eastern Railway. The LNER was the second largest railway company in Britain, its routes were located to the north and east of London. On 1 January 1948, the Transport Act of 1947 implemented by Clement Attlee's Labour Government, nationalised the LNER and other privately owned railway companies to form British Railways. British Railways managed the ECML as its Eastern Region up to its discorporation in the early 1980s.
Alterations to sections of the ECML's 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 bypassing anticipated mining subsidence from the Selby coalfield and a bottleneck at Selby station. The Selby Diversion which diverged from the ECML at Temple Hirst Junction, north of Doncaster and joined the Leeds to York Line at Colton Junction south west of York opened in 1983. The old line between Selby and York was dismantled and is now a public cycleway.
No. 2547 Doncaster hauls the daily Flying Scotsman in 1928.
The line was temporarily realigned while the ground was stabilised when mining subsidence affected 200 metres of track 17 km to the east of Edinburgh, near Wallyford. The tracks were re-routed as was the overhead electrification equipment and the work was completed in 2000 when the track was returned to its original alignment. In 2001, severe subsidence was discovered at nearby, Dolphinstone and about 2 km of track was permanently moved laterally in a gentle curve to avoid a permanent speed restriction in 2002.
The line was worked for many years by Pacific steam locomotives designed by Sir Nigel Gresley, including the "Flying Scotsman" and "Mallard". Mallard achieved a world record speed for a steam locomotive, having attained a recorded top speed of, while traversing the Grantham-to-Peterborough section on the descent of Stoke Bank. To date, the speed record set by Mallard has not been broken.

Diesel era

In the early 1960s, steam locomotives were replaced by Diesel-electrics, amongst them the Deltic, a powerful high-speed locomotive developed and built by English Electric. The prototype was successful and a fleet of 22 locomotives were built and put into BR service for express traffic. Designated the, they were powered by a pair of Napier Deltic engines that had been developed for fast torpedo boats; the unusual three-crankshaft triangular configuration of the engines was the source of the locomotive's Deltic moniker. Their characteristic throaty exhaust roar and body outline made them unmistakable and distinctive amongst their peers. The Class 55 was for a time the most powerful diesel locomotive in service in Britain, capable of providing up to.
In the years following the introduction of the Deltics, sections of the ECML were upgraded for trains running at speeds of up to. On 15 June 1965, the first length of high-speed line, a stretch between Peterborough and Grantham, was completed. The next section was of line between Grantham and Newark and more sections were upgraded to enable high speeds along much of the line.
As the demand for higher speed intensified, British Rail produced a successor to the Deltics, the high speed train, which was introduced between 1976 and 1981. Capable of, it was a popular and iconic train and remained in passenger service in 2018 after a re-engining programme during the 2000s, in which MTU engines replaced the HST's original Paxman Valenta power units.
In 1973, the prototype HST British Rail Class 41 recorded a top speed of in a test run the line. British legislation required the use of in-cab signalling for running at speeds in excess of and so regular trains services were unable to run at such speeds. The lack of in-cab signalling was the primary reason that prevented the InterCity 225 train-sets from operating at their design speed of during normal service. A secondary factor was that the signalling technology of the time was insufficient to allow detection of two broken rails on the running line.
Before current in-cab regulations were introduced, British Rail experimented with 140 mph running by introducing a fifth, flashing green signalling aspect on the Down Fast line and Up Fast line 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 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 in test runs. The capability to run special test trains in excess of 125 mph is listed as being maintained in the LNE Sectional Appendix.

Electrification

In the 1930s, studies were conducted into electrifying sections or all of the ECML. While British Rail considered electrification to be of equal importance to the West Coast Main Line and ECML during the 1950s, political factors delayed ECML electrification. Instead, investment was in high-speed diesel traction, the Deltic and high-speed train, for implementing service improvements.
Between 1976 and 1991, the ECML was electrified with 25 kV AC overhead lines, which were installed in two phases: The first phase between London and was carried out between 1976 and 1978 as the Great Northern Suburban Electrification Project, using Mk.3A equipment over 30 miles in total.
A working group of British Rail and Department for Transport officials convened in the late 1970s determined that, of all options for further electrification, the ECML represented the best value by far. Its in-house forecasts determined that increases in revenue and considerable reductions in energy and maintenance costs would occur by electrifying the line. In 1984, the second phase commenced to electrify the Northern section to Edinburgh and Leeds. The Secretary of State for Transport Nicholas Ridley and Minister for Railways David Mitchell played a large role in the decision to proceed.
The programme covered roughly 1,400 single-track miles and required major infrastructure changes, including resignalling the northern part of the line from Temple Hirst junction near Selby to the Scottish border and new signalling centres at Niddrie, York and Newcastle, ten power supply points at key points on the line, and clearance and immunisation activity to protect equipment. The ECML was crossed by 127 overbridges which were adjusted to accommodate the change. It was decided to rebuild individual bridges as opposed to lowering the track or other compromises. Some overbridges, such as the aqueduct near Abbots Ripton, were subject to innovative alterations to accommodate the installation of the overhead lines and on listed structures, such as the Royal Border Bridge, a specially-developed mast and foundation were used; elsewhere the standard Mk.3B equipment was deployed.
In 1985, construction began on the second phase; in the late 1980s, the programme was claimed to be the "longest construction site in the world", spanning more than. In 1986, the section to Huntingdon was completed, Leeds was reached in 1988 and the line to York was energised in 1989; by 1991, electrification had reached Edinburgh and electric services began on 8 July, eight weeks later than scheduled. Significant traffic increases occurred in the two years after completion; one station recorded a 58 per cent increase in passengers.
Electrification was completed at a cost of £344.4 million, a minor overrun against its authorised expenditure of £331.9 million. 40 per cent of the total cost was on new traction and rolling stock and 60 per cent for the electrification of the line. Shirres compared the ECML and later Great Western Railway electrification programmes, noting a 740 per cent increase in cost between the former and the latter; in this respect, the ECML scheme was more cost effective. The infrastructure supported speeds of up to 140 mph on a 3hr 29mins non-stop run between London and Edinburgh on 26 September 1991. British regulations have since required in-cab signalling on any train running at speeds above preventing such speeds from being legally attained in regular service.
In 1989, InterCity 225 rolling stock was introduced on the line. They were developed to a competitive tender, to which GEC was awarded the contract. The Intercity 225 sets were used alongside other rolling stock, including locomotives and electric multiple units. The displaced diesel trains were reallocated predominantly to the Midland Main Line.

Infrastructure

The line is mainly quadruple track from London to Stoke Tunnel, south of Grantham with two double track sections, one near Welwyn North Station where it crosses the Digswell Viaduct and passes through two tunnels. The second is between Fletton Junction near Peterborough, and southwards towards Holme Junction. The section between Holme Junction south and Huntingdon is mostly triple track. North of Grantham the line is double track except for quadruple-track sections at Retford around Doncaster, between Colton Junction, Thirsk and Northallerton, and Newcastle.
The main line is electrified along its full length but the line between Leeds and York is not electrified. This line is in the Transpennine electrification scheme.
With most of the line rated for operation, the ECML was the fastest main line in the UK until the opening of High Speed 1. The high speeds are possible because much of the line is on fairly straight track on the flatter, eastern side of England, through Lincolnshire and Cambridgeshire, though there are significant speed restrictions because of the line's curvature particularly north of Darlington and between Doncaster and Leeds. By contrast, the West Coast Main Line crosses the Trent Valley and the mountains of Cumbria, with more curvature and a lower speed limit of. Speeds on the West Coast Main Line were increased with the introduction of tilting Pendolino trains and now match the 125 mph speeds on the ECML.

Future

Operators

The line's current principal operator is London North Eastern Railway, whose services include regular trains between King's Cross, the East Midlands, Yorkshire, the North East of England and Scotland. LNER is operated on behalf of the Department for Transport by a consortium of Arup Group, Ernst & Young and SNC-Lavalin Rail & Transit and took over from Virgin Trains East Coast on 24 June 2018.
Other operators of passenger trains on the line are:
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 overnight Caledonian Sleeper operated by Serco occasionally uses the ECML when engineering works prevent it from using its normal train path on the WCML.
DB Cargo UK, Direct Rail Services, Freightliner and GB Railfreight operate freight services.
In 2019 FirstGroup and Hitachi Rail secured rights from the Office of Road and Rail to run a new ‘open access’ service between the two capitals.

Development

Capacity problems

The ECML is one of the busiest lines on the British rail network and there is 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:
Railway operations 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-reduction measure was the use of headspan catenary support systems over the quadruple track sections – as employed in the Weaver Junction to Glasgow Electrification on the WCML during the 1970s. Headspans do not have mechanically independent registration of each electrified road and thus are more complex to set up, compared to TTC and portal style support structures, during installation. In the event of a de-wirement of a given road, headspans result in the need to correctly set up the OLE of adjacent roads before the line can reopen to electric traction. This was a result of extreme pressure from the Department for Transport to reduce avoidable costs when the line was originally electrified between 1985 and 1990.

Recent developments

The European Union Directive 96/48/EC, Annex 1 defines high-speed rail's minimum Speed Limit as on existing lines which have been specially upgraded.
Over the years successive infrastructure managers have developed schemes for route improvements. The most recent of which is the £247 million "ECML Connectivity Fund" included in the 2012 HLOS with the objective of increasing capacity and reducing journey times. Current plans include the following specific schemes:
And on a more route wide basis the following projects:
Once the High Speed 2 project is completed, it will supersede the ECML as the primary link between London and Edinburgh. A link between HS2 and the ECML will be constructed south of York and high speed services will continue to use the ECML north of this junction to reach York, Darlington, Durham, and Newcastle. The removal of high speed services from the southern end of the ECML will allow more local services to run.

Popular culture

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 King's Cross to Newcastle in the opening credits. During 2009, the motoring show Top Gear featured a long distance race, in which LNER A1 60163 Tornado, a Jaguar XK120 and a Vincent Black Shadow competed to be the fastest vehicle to travel the full length of the line from London to Edinburgh.
The route has been featured in several train simulator games. Trainz Simulator 2010 features the route between London and York, Trainz Simulator 12 extends the route to Newcastle, and Trainz: A New Era brings it all the way to Edinburgh, allowing the entire 393-mile route to be driven. All three routes take place during the 1970s, around the time the InterCity 125 was introduced; this is reinforced by instructions in the "HST Southbound Express" session not to move until the guard has locked the doors, since the trains did not have pneumatic locks initially; doing so will lead to an automatic failure. Other rolling stock includes Class 37s, Class 47s, and Class 105s, plus Mark 2 coaches. TS12's version added Class 55 Deltics and Class 313s, as well as additional pre-made, pre-scripted sessions.
King's Cross Station is also known as the starting point of the Hogwarts Express from the books and films of the Harry Potter franchise. This connection is marked by a tourist attraction within the station concourse, featuring the Platform 9¾ sign and a luggage trolley partially embedded in the station wall with an owl cage and suitcases on it.
