Unlike the West Coast and East Coast Main Lines, the Midland Main Line has not been electrified along its full length. The line was electrified as far as Bedford in the early 1980s, but services relied on diesel traction beyond that.

In 2011 work commenced to extend the electrification, including to both Corby and Nottingham. Increasing costs initially saw this terminated at Kettering in 2017, but in 2021 work began on extending electrification to Market Harborough and onwards to Wigston with plans to extend further to Sheffield.<ref>{{Cite web|url=https://www.railwaygazette.com/uk/electrification-to-reach-market-harborough/48150.article|title=Electrification to reach Market Harborough}}</ref><ref>{{Cite web|title=Spades in ground as government delivers on rail investment promise for North and Midlands|url=https://www.gov.uk/government/news/spades-in-ground-as-government-delivers-on-rail-investment-promise-for-north-and-midlands|access-date=2021-12-21|website=GOV.UK|language=en}}</ref><ref>{{Cite web|date=2021-12-21|title=Main works on next stage of Midland Main Line electrification due to begin|url=https://news.railbusinessdaily.com/main-works-on-next-stage-of-midland-main-line-electrification-due-to-begin/|access-date=2021-12-21|website=RailBusinessDaily|language=en-US}}</ref><ref>{{Cite web|title=Rail industry welcomes progress on Midland Mainline electrification|url=https://www.riagb.org.uk/RIA/Newsroom/Press_Releases/Progress_on_MML_electrification.aspx|access-date=2021-12-21|website=www.riagb.org.uk}}</ref>

In May 2022, a briefing to contractors was released ahead of an invitation to tender for Midland Mainline Electrification project work to extend electrification to Nottingham and Sheffield. This scheme is expected to cost £1.3&nbsp;billion.<ref>{{cite web|url=https://www.newcivilengineer.com/latest/contractors-alerted-to-next-phase-of-1-3bn-midland-main-line-electrification-24-05-2022/ |title=Contractors alerted to next phase of £1.3bn Midland Main Line electrification |date=24 May 2022 }}</ref>
