Proposed railway electrification in Great Britain


Proposed railway electrification in Great Britain. In 2009, Lord Adonis was appointed Secretary of State for Transport. After a gap of more than a decade, electrification was back on the agenda and Adonis announced plans to electrify the Great Western Main Line from London as far as Swansea, as well as infill electrification schemes in the North West of England.
In July 2012 the UK government announced £4.2 billion of new electrification schemes, all at 25 kV AC and reconfirmed schemes previously announced by Adonis. These were to be Northern Hub, Great Western Main Line, South Wales Main Line, Midland Main Line, Electric Spine, Crossrail, Gospel Oak to Barking Line and West Midlands suburban lines including the Cross-City Line.
Rail transport in Scotland is a devolved matter for the Scottish Government, but they too have pursued electrification with multiple schemes in the Central Belt. All these have been 25 kV AC, as in England and Wales.
On 25 June 2015 the government announced that some of the electrification projects would be delayed or cut back because of rising costs. Electrification work was to be "paused" on the Trans-Pennine route between York and Manchester and on the Midland main line between Bedford and Sheffield. Electrification of the Great Western main line would go ahead but the status of the Reading-Newbury and Didcot-Oxford sections was unclear.
However, in September 2015, the electrification work was "un-paused", but with a delayed completion date. Since then there have been regular updates including one published in October 2016.
On 20 July 2017 Chris Grayling the Secretary of State for Transport cancelled a number of electrification projects citing disruptive works and use of bi-mode technology as an alternative. In June 2018,
Electrification has not been without controversy with cancellations and various appearances of the Secretary of State for Transport called before the Transport Select Committee. The Transport Select Committee published its report into various matters including regional investment disparity on the railways and calling again for the reinstatement of various cancelled electrification schemes.
A written question was submitted and answered in parliament regarding route miles electrified in the years 1997-2019.
In March 2019 the Railway Industry Association published a paper on Electrification cost challenge suggesting ways forward and a rolling program of electrification.

Existing routes

Proposed routes

Northern Hub

As part of the Northern Hub project, the following lines in North West England and Yorkshire are to be electrified:
Main article: Midland Main Line
Main article: Electric Spine
New cross-London main line, originally due to open in December 2018. Opening has been delayed until 2021.

Gospel Oak to Barking Line

Extensions to the existing West Midlands suburban electrification:

[Edinburgh to [Glasgow Improvement Programme]] (EGIP)

This electrification scheme and associated works has come to mean Edinburgh-Glasgow via Falkirk High and was due to be completed by December 2016. The rolling programme would then follow with the route via Shotts. The scheme via Carstairs in association with the ECML electrification was completed in the early 1990s. With other infills in the central belt of Scotland there will soon be 4 different electrified routes between the two cities with assorted diversionary routes.
The December 2016 date was not met and in May 2017 a further delay to the wires going live was announced due to a safety-critical component possibly for the whole route needing to be replaced.
It was actually completed in December 2017.
The infills include the route from Cumbernauld and Falkirk Grahamston to Larbert, Alloa, Dunblane and Stirling.

Rolling program

On 28 July 2020, Scottish Transport Secretary Michael Matheson announced plans to phase out fossil fuel use on the railway network by 2035. The plan would see most lines electrified, but suggests that intermittent electrification in difficult places may be implemented. Alternative traction will be implemented rather than electrification for some lightly-used lines. These are the Far North Line, Kyle of Lochalsh Line, West Highland Line, and the southern portion of the Stranraer Line.
