The Levenmouth area was the largest urban area in Scotland unserved by any direct rail link, with a population of around 33,000. The catchment area of the line, which includes parts of the
East Neuk of Fife, is around 43,000, and as such was identified by
Campaign for Better Transport as a priority 1 candidate for reopening. Campaigns for the reinstatement of passenger services on the route have occurred since passenger services were withdrawn in 1969. There was a significant increase in campaigning in 2008, when the
Airdrie–Bathgate rail link and
Borders Railway were being authorised by the Scottish Parliament. Fife Council put forward £2 million to support the reopening, with the costs initially estimated at £28 million. This estimate was later increased to £45–55 million by the end of 2008. SESTRAN conducted a feasibility study and Fife Council declared the project as a top-priority transport project. A third STAG report was prepared during 2018 and early 2019 for Transport Scotland. The preliminary options appraisal looked at a total of twelve improvements to public transport for the Levenmouth area, including upgrading bus services between Levenmouth and existing stations on the Fife Circle rail line, new rapid bus services between Levenmouth and Edinburgh, an entirely new railway on a new alignment between Markinch and Levenmouth, a
hovercraft service between Levenmouth, Kirkcaldy and Edinburgh, and reinstatement of the disused railway between Leven and Thornton North Junction. These were reduced to a total of six options in the preliminary options final report in May 2019: the only remaining rail option was the reinstatement of the line between Leven and Thornton Junction. The remaining five options were a series of upgrades to public transport facilities and bus services, and improvements to 'active travel networks' which would see improved walking and cycling opportunities in combination with any upgrades to bus services and the reintroduction of rail services. The Scottish Government announced on 8 August 2019 that the line would be re-opened for passenger and potential freight services. Passenger services began on Sunday 2 June 2024. There will also be improvements to walking and cycling routes. In May 2021 sleepers for the line were delivered The main delivery phase of the project kicked off in March 2022 and work at Leven station began in February 2023. By January 2024, infrastructure works were largely completed, with testing and driver training underway. The route was formally opened on 29 May 2024 by First Minister
John Swinney, with scheduled service commencing on 2 June 2024. In September 2025, Transport Secretary
Fiona Hyslop announced that the plans to electrify the Levenmouth rail link along with Borders Railway would go ahead, with work near Leven already started. ScotRail is to procure new battery electric trains to run on the route, replacing the existing 40 year old stock. These will run on battery between
Kinghorn and
Dalmeny over the
Forth Bridge. The construction works are estimated to be completed by 2029, with the new trains running by 2031. == Service provision ==
