Midland Main Line

Overview

The Midland Main Line is the railway from London St Pancras to Sheffield, running through the East Midlands of England in the United Kingdom and serving the region’s three biggest cities. Network Rail, which owns the infrastructure, says the line reaches Sheffield at its most northerly point and is currently undergoing the largest upgrade since it was completed in 1870 (Network Rail).

Rail Technology Magazine likewise calls the current electrification programme the most extensive upgrade to the line since its completion in 1870 (Rail Technology Magazine). The line is electrified from London to Wigston, south of Leicester, while electrification further north has been paused indefinitely (East Midlands Business Link). It is also the line blocked by the 2008 Barrow upon Soar derailment (Rail Technology Magazine).

Built in stages: from coal lines to a London terminus

1839–1844: the Midland companies

The Midland Main Line grew out of local coal railways, and Derby was its first hub. The first railway train steamed into Derby from Nottingham on 30 May 1839, and five days later the Midland Counties Railway started a regular passenger service between Derby and Nottingham (Discover Derby). Derby station was completed during the summer of 1840, and cut-throat competition between the three railway companies serving the town was solved in 1844 with their amalgamation, forming the Midland Railway on 10 May 1844 (Discover Derby). The new company expanded rapidly: it reached Manchester in 1867, London a year later, Swansea in 1874 and Scotland a year later via the Settle and Carlisle line (Discover Derby).

Completion in 1870 and the St Pancras terminus

Network Rail dates the line’s completion to 1870, and describes the current upgrade as the largest since that completion (Network Rail). The Midland Railway, formed in 1844 from three companies, built the line in stages across three decades (Discover Derby). Rail Technology Magazine agrees, calling the electrification programme the most extensive upgrade to the line since its completion in 1870 (Rail Technology Magazine). The two dates in the sources need care: the Midland reached London in 1868, when its extension to St Pancras opened, while 1870 marks the completion of the through line as Network Rail reckons it (Discover Derby; Network Rail). St Pancras has remained the line’s southern terminus ever since (Network Rail). This profile therefore treats 1868 as the London extension and 1870 as the completion of the through line, and flags the distinction openly.

Route and services

The route today

The Midland Main Line runs from London St Pancras and reaches Sheffield at its most northerly point, serving the three biggest cities of the East Midlands — Leicester, Derby and Nottingham — plus East Midlands Parkway for connections to the region’s airport (Network Rail). Network Rail presents the line as part of its wider East Midlands route, which takes in the whole of the East Midlands including Derby, Nottingham and Leicester (Network Rail). That East Midlands route as a whole has 1,500 employees who help run around 1,400 trains per day, calling at 99 stations and looking after 622 level crossings — route-wide figures, not figures for the Midland Main Line alone (Network Rail). Work is ongoing to electrify the Midland Main Line, with the promised result of smoother, more reliable, quieter and greener journeys between South Yorkshire, the East Midlands and London (Network Rail). The line thus serves both inter-city travel and the suburban commuter links outside London (Network Rail).

The 2008 derailment at Barrow upon Soar

On 1 February 2008, the 06:13 Nottingham to Norwich train collided at Barrow upon Soar in Leicestershire with debris from a footbridge knocked down by the raised body of a tipper lorry; the train derailed and continued for 170 metres (RAIB). The train derailed but remained upright, and the Midland Main Line remained blocked, with London services terminating at Leicester (Rail Technology Magazine). Engineers worked through the night, two of the four lines were reopened by 04:00 the following day, and the remaining two were due to reopen by teatime (Rail Technology Magazine). The Rail Accident Investigation Branch investigated and made recommendations to Network Rail on assessing risks during road-vehicle transit operations near the running line, and to the Rail Safety and Standards Board on train design (RAIB). The full account is in the Barrow upon Soar rail crash profile, which this profile links to rather than repeating.

Electrification: the stop-start upgrade

Kettering to Wigston goes live

On Sunday 28 July 2024, 25,000 volts of electricity was switched on between Kettering and Wigston as work continued on the wider Midland Main Line Upgrade (Network Rail Media Centre). The 36km section was electrified by Network Rail and its contractor SPL Powerlines, and the wires will power new bi-mode diesel-and-electric trains through the area (New Civil Engineer). Three new substations provide power to the route, including East Langton, and the Braybrooke Feeder Station feeds 25,000 volts to Corby and down to Sharnbrook (Network Rail Media Centre). Seven bridges and four signal gantries on the section use voltage controlled clearance technology, avoiding bridge rebuilds and lengthy road closures, and the Office of Rail and Road issued the Authorisation to Place into Service for the section (Rail Technology Magazine). The work was delivered on time and under budget, and builds on the previous completion of London to Corby (Rail Technology Magazine).

Pause beyond Wigston

Kettering–Wigston sits inside a longer stop-start story. Electrification from London northwards started in 1981 but was terminated at Bedford in 1983, and the scheme has faced repeated delays and cancellations over 45 years despite commitments from successive governments (East Midlands Business Link). In 2009 Labour prioritised Great Western, but in 2012 the Coalition committed to full electrification by decade’s end; the scheme was paused in 2015, cancelled in 2017 and resurrected in the 2021 Integrated Rail Plan (East Midlands Business Link). Procurement of the next phase through Leicester into Nottinghamshire was delayed by the 2024 election and spending review, and the scheme is now indefinitely paused (East Midlands Business Link). The line is now the only mainline route largely non-electrified, and the East Midlands is the most diesel-dependent region in Great Britain, with East Midlands Railway refurbishing 25–35-year-old diesel trains to run a decade longer (East Midlands Business Link).

Frequently asked questions

Where does the Midland Main Line run? It runs from London St Pancras to Sheffield, serving the East Midlands’ three biggest cities — Leicester, Derby and Nottingham — plus East Midlands Parkway for the region’s airport. Network Rail describes it as the East Midlands route’s main line, with Sheffield as its most northerly point and London as its southern terminus.

When was the Midland Main Line completed? Network Rail and Rail Technology Magazine date the line’s completion to 1870, and describe the current upgrade as the largest since then. The Midland Railway had reached London in 1868, when its St Pancras extension opened, so 1868 marks the London extension while 1870 marks the completion of the through line.

How much of the line is electrified? The line is electrified from London to Wigston, south of Leicester, via Kettering and Corby. The 36km Kettering to Wigston section was energised on 28 July 2024 with 25,000-volt overhead wires. Electrification north of Wigston, towards Leicester, Nottingham, Derby and Sheffield, has been paused indefinitely.

Why has electrification stopped and started so often? The scheme has faced repeated delays and cancellations over 45 years despite commitments from successive governments: terminated at Bedford in 1983, paused in 2015, cancelled in 2017, revived in the 2021 Integrated Rail Plan, then paused again after the 2024 election and spending review. Regional leaders argue each pause damages confidence and makes delivery more expensive.

What happened on the line at Barrow upon Soar in 2008? On 1 February 2008 the 06:13 Nottingham to Norwich train collided with debris from a footbridge knocked down by a tipper lorry’s raised body, derailed and ran on for 170 metres. The Midland Main Line was blocked, London services terminated at Leicester, and two of the four lines reopened by 04:00 the next day. The RAIB investigated.

What this profile does not claim

• It does not give a complete station-by-station list for the line, because no fully-read source verified one; it names only places its sources place on the line.
• It does not resolve the 1868-versus-1870 framing beyond the distinction stated above; the sources do not spell out how the two dates relate, and the profile flags that openly.
• It does not predict when, or whether, electrification north of Wigston will resume; the pause is reported as indefinite by the regional press account.
• It does not describe the 2008 derailment beyond the RAIB summary and the Rail Technology Magazine aftermath account; the full investigation belongs to the crash profile.
• It does not assert a current timetable, frequency or journey time for the line, because no fully-read source verified one.
