This work enabled a partial train service to continue to run on the East Coast Main Line while the tunnel was being pushed into place in January During a nine-day partial closure of the East Coast Main Line in January , the 11, tonne, metre curved concrete box tunnel was pushed into place. Time-lapse footage below shows the 11, tonne curved concrete box being pushed under the East Coast Main Line..
Whilst hydraulic jacks at the rear pushed the tunnel portal forwards at just cm per hour, excavators at the front broke away the guide tunnels to reveal the glide plates to guide and steer the tunnel into position. This is the first time that a curved concrete box has been installed using this industry-leading engineering technique in the UK. Teams removed three of the tracks, lifted the overhead wires and dug out spoil from the site.
Once the tunnel was eventually underneath, they then put everything back in place ready for regular services to resume. This project is one of the most significant on the East Coast Main Line and involves major construction activity that has the potential to be disruptive to residents and businesses at specific points in time.
We will continue to everyone affected in advance of this type of work. Unfortunately, the series of community events have been cancelled due to Covid We endeavour to re-start these as soon as possible.
We are sorry for any inconvenience caused. A secondary factor was that the signalling technology of the time was insufficient 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 mph running by introducing a fifth, flashing green signalling aspect on the Down Fast line signals P to P and Up Fast line signals P to P 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 mph.
The capability to run special test trains in excess of mph is listed as being maintained in the LNE Sectional Appendix [7]. This included the Hertford Loop Line.
Construction began in , and the section between Hitchin and Peterborough was completed in , Doncaster and York were reached in By electrification had reached Newcastle, and in Edinburgh.
At the peak of the electrification project during the late s, it was claimed to be the "longest construction site in the world" at over miles. The current InterCity rolling stock was introduced in to work the electrified line. The line is mainly four tracks from London to Stoke Tunnel, south of Grantham. However, there are two major 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 a section around 'Stilton Fen', between Fletton Junction near Peterborough, and southwards towards Holme Junction; furthermore, the section between Holme Junction south to Huntingdon is mostly triple track.
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. The main route is electrified along the full route and only the line between Leeds and York Neville Hill Depot to Colton Junction is non-electrified. This diversionary route will be electrified as part of the transpennine electrification scheme, to be completed by December These relatively high speeds are possible because much of the ECML travels on fairly straight track on the flatter, eastern regions of Great Britain, through Lincolnshire and Huntingdonshire , 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 Cumberland and Westmorland , leading to many more curves and a lower general speed limit of mph. Note that although the line passes through Rutland and Berwickshire there are no stops in either county. Jump to: navigation , search. Midlothian Edinburgh Waverley Musselburgh Wallyford.

Although some earlier intentions, such as removing Newark flat crossing and quadrupling Digswell Welwyn Viaduct and Peterborough-Huntingdon have apparently receded, the ECML remains set for significance improvements. A flyover at Hitchin will allow services down from Cambridge to leave the main line without obstructing other ECML movements as at present.
Peterborough, 80 miles north of London and on the limits of outer suburban operations, is to receive a much-needed extra island platform to allow more segregation of East Anglian-Midlands passenger and freight paths from those for the ECML.
After patchy initial performance, reliability was greatly improved by a re-build carried out at Doncaster. The project encompassed a mph line between London, Birmingham and Manchester, with incremental improvements elsewhere.
The chamfered bodysides of the Mark 4s have proven to be an unnecessary intrusion into passenger space, as the tilt mechanism for which the shape allows will never be fitted. Diesel mph HSTs are used to serve non-electrified destinations Hull, Harrogate, Inverness and Aberdeen and, although fully under the wires, to cover some of the increased frequency to Leeds from Their formations have been lengthened with an extra coach and an internal refit to match the Mk4s began in Class units cover inner suburban services, their dual voltage capability used on the city branch to Moorgate.
This incorporates automatic train protection controls and trains receive in-cab signalling information from lineside transponders. Related to new stock, full resignalling and crossing replacements, full implementation could take up to Controlled from seven signal boxes and fully signalled with colour lights, most signalling was renewed when the line was electrified.
The route is equipped for bi-directional running between Glasgow and Berwick-upon-Tweed. GNER became the first UK train company to offer uninterrupted Wi-Fi internet connections for all passengers, both first and standard class. The new franchise operator is committed to making this free in both classes and providing better on-board and station information systems, plus more electronic ticketing options that will extend to car parking.
This will require the capability of handling coach trains for the service, which will encompass Peterborough and Cambridge line trains and a range of destinations south of the Thames.
