The "Electric Spine" is the name for part of a rolling programme of railway electrification projects in England estimated to cost £800 million. The aim is to form 25 kV AC overhead-wire electrified links northward from the Port of Southampton to major cities in northern and central England and a dry port container terminal in the Midlands. The government wants efficient electric-hauled freight trains to compete with road haulage, and in 2012 expected the spine to be completed with Network Rail's Control Period 5 (CP5, 2014–2019). This will not be the case, because various works have been delayed and a major constituent programme—the electrification of the Midland Main Line (MML)—was suspended for several months. In 2015, newly appointed head of Network Rail, Peter Hendy, moved many Electric Spine projects to development and delivery in Control Period 6 (CP6) starting in 2019.

Other works associated with the project will include gauge clearance for large shipping containers and electrified connections to adjacent electrified routes, depots and freight facilities.
The north–south axis of the link leads to the spine name.
Routes
A high-capacity passenger and freight corridor will run from the south coast through Basingstoke and Reading to Oxford, where it will split. One branch will run to Leamington Spa, Coventry, and the west Midlands, and another will use the re-instated East West Rail Link to Bletchley (Milton Keynes) for the West Coast Main Line (WCML) to the West Midlands, north-west England and Scotland, and also onward to Bedford for the MML to the East Midlands, Sheffield and south Yorkshire.
Constituent projects
The various projects to create the spine are at different stages of development, and will be completed at different times. The initially prioritized works are fully planned and under way as part of CP5 (i.e., works for 2014–2019). Some projects will be planned and undertaken in CP5, others will be planned in CP5 for completion in the following Control Period, and some remain yet to be firmly committed to.
East West Rail Link
The rebuilt 46 mile-long East West Rail Link from Oxford (via Bicester and Bletchley) to Bedford will be electrified as an integral part the Electric Spine. This will include the Oxford to Bicester Line, a rehabilitated stretch of the Buckinghamshire Railway from Bicester to Bletchley (and a junction with the WCML), and the Marston Vale Line from Bletchley to Bedford (where it meets the MML). The Bicester to Bletchley section will be double track with a line speed of 100 mph. This phase is due to be completed in 2019. As of April 2015 however, electrification and track upgrade of the Bletchley to Bedford section is planned but not scheduled, and greater work on the East West Rail Link than that scheduled for CP5 would be needed to achieve the Electric Spine.
Midland Main Line
The electrification of the MML will be extended northward from its limit at Bedford. Bedford to Derby was originally scheduled to be electrified by 2019, but the work was "paused" in June 2015 despite significant progress having already been made. The electrification to Derby and beyond (e.g., from Trent Junction via Derby to Sheffield—completion originally due in December 2020—and also to Doncaster—originally due June 2021) will be much delayed. On 30 September 2015, the Department for Transport announced the resumption of the work with revised completion dates of 2019 for Corby and Kettering and 2023 for the line further north to Leicester, Nottingham and Sheffield.
Bridges and other structures have been replaced to allow space for the overhead cables and also a larger loading gauge.
Derby and Leicester station areas remodelling
Derby railway station, a junction station on the MML, will have remodelled track and signalling: trains approaching from the north will be segregated from those approaching from the south and west, thus removing the current bottleneck at the station. The work was set for completion in December 2017, but was later pushed back to October 2018. The MML around Leicester is also being considered for capacity-improvement, but the plans are less well developed than those for Derby, and are due to be finalised in CP6.
Electrification of the Great Western Main Line and the Reading to Basingstoke Line
Part of the planned-to-be-electrified Great Western Main Line (GWML) (from Reading to Didcot) will form part of the Electric Spine. The electrification of this part of the GWML will also include the Cherwell Valley Line from Didcot Parkway to Oxford, which was announced in 2009 as part of the 21st Century modernisation of the GWML. A freight curve at Reading bypasses the station and connects the GWML to the Reading to Basingstoke Line (14 miles), which will take the spine south to Basingstoke and onward to Southampton. The Didcot to Oxford electrification, under way and initially due for completion in 2016, was delayed indefinitely in November 2016. The Reading to Basingstoke electrification, planned as part of CP5, As of April 2015 had no expected completion date.
Leamington Spa to Coventry line
Of the western branch of the spine from Oxford, only the Coventry to Leamington Line (9 miles) was initially prioritized for the 2014–2019 period of works. It will be electrified and the track doubled. However, it—along with other works—has been delayed into CP6.
Required works not scheduled for 2014–2019
Overall, the line north from Oxford to Nuneaton is scheduled for "single option development" (the stage before detailed design) within CP6, and no completion date is given. This includes the northern part of the Cherwell Valley Line from Oxford to its junction with the Chiltern Main Line near Banbury, the Chiltern Main Line from Banbury to Leamington Spa (Oxford to Leamington: 43 miles), the Coventry to Leamington line, and the Coventry to Nuneaton Line (9 miles).
The South Western Main Line, which runs 34 miles from Basingstoke to Southampton and its port, is currently third rail DC electrified, and will eventually be converted to AC overhead. This test-section of re-electrification will assess the feasibility of the wider conversion of the third-rail electric network to overhead. As mentioned above, electrification from Bletchley to Bedford is also not yet scheduled. Network Rail intends to develop plans for both projects in CP6.
Reactions
The managing director of GB Railfreight, John Smith, has questioned the prioritisation of the Electric Spine over other freight routes: "I [do not] really understand some of the details of the electric spine. We are reviving and electrifying a stretch of railway between Oxford and Bletchley that’s been out of use for 20 years, before we electrify across Suffolk [for access to the Port of Felixstowe], double the Felixstowe branch or deal with the Immingham approaches." He stated that "the majority of electrification schemes in the UK [are to] support the passenger network."
Other freight companies' managers also have doubts in the project's benefit to freight transport given the lack of priority given to the lines to the major ports.
