Midland Main Line upgrade

Summary

The Midland Main Line (MML), a major railway line in the United Kingdom, has undergone various upgrades between 2015 and 2025. The current programme of upgrades began in 2012, although electrification was proposed a number of times previously. The programme includes electrification of the railway line between Bedford, Wellingborough, Corby, Leicester, Derby, Nottingham and Sheffield. The routes between Nottingham and Sheffield and the Erewash Valley line were not included at this time, only the line between Derby and Sheffield. The upgrade was part of the HLOS for Control Period 5 published by the UK Government in 2012.
