Fife Electrification

Fife Electrification

Electrification of the Fife Circle and routes connecting Fife to Edinburgh and Dundee.

The Fife Electrification project is the next part of the Scottish Government’s rolling programme of electrification. This major investment in Scotland’s Railway will electrify the railway to enable the introduction of a new fleet of more reliable, greener and more accessible trains. 

Reducing carbon emissions will not only improve rail’s green credentials but will make the air cleaner and play a vital part in building a strong, green economy for the future.

Trains running in Fife are coming to the end of their life and need to be replaced. The Fife Electrification project will enable the introduction of new battery-electric trains to replace those older diesel trains.

Project Updates

  • Thornton - Main Street bridge replacement

  • Kirkcaldy - Bennochy Bridge replacement

    Bennochy Road bridge in Kirkcaldy is being rebuilt, to create the room needed underneath to install new overhead wires.

    Until July 2027, the road is closed to allow the bridge to be rebuilt safely. A road diversion is in place throughout which involves several months of diverting undeground utilities before the bridge can be demolished and rebuilt.

    All of this is part of our work to electrify the railway in Fife.

  • Cardenden - New accessible footbridge

    As part of the electrification project a new accessible bridge will be installed at Cardenden Station. 

    This will replace the current footbridge and once it’s complete, lifts will provide step-free access between platforms, making it much easier for those with mobility challenges, the elderly, and those travelling with children, luggage or prams.

    The project will take around nine months and the current footbridge will remain in place until the new one is constructed, so access will remain between the platforms.  

    The bridge needs to be replaced to make room for the new overhead wires which will power battery electric trains to be installed.  

    Elsewhere in Cardenden, we will be replacing the bridge deck at Cardenden Road (Old Bridge).  

    The new structure will be stronger and more resilient, supporting Network Rail’s commitment to maintaining a safe and reliable railway for passengers and freight. 

    This work is scheduled to start from 17 August until 18 December 2026, with a road and pedestrian diversion in place.  

    Although this bridge replacement is not part of the electrification project, delivering both schemes at the same time helps reduce overall disruption to the community by not having to do this work separately at a later date. 

  • October Engineering work

    Rail passengers in Fife are being asked to plan ahead this October as we carry out a major programme of engineering as part of the Fife Electrification Project. 

    The work is part of the Scottish Government's £311.5m investment to electrify 118km of the route to introduce new battery-electric trains, supporting the wider modernisation of Scotland's railway and a move towards more sustainable transport. 

    Over 18 days, engineers will carry out bridge replacements, track and signalling upgrades, and other improvements in the area to clear the way for the installation of new overhead power lines.

    Three planned rail closures will allow teams to complete some of the most complex parts of the project safely and efficiently: 

    • Inverkeithing and Thornton North: 10 to 20 October 
    • Thornton North, Cupar and Hilton Junction: 20 to 24 October 
    • Lochgelly and Glenrothes: 24 to 28 October. 

     

    Find out more about the programme of work for October. 

Why?

The project will enable a new battery-electric train fleet to be introduced – improving reliability, increasing efficiency and better matching capacity to demand.

Decarbonising the railway, beyond delivering a reduction in carbon emissions, helps reduce the ongoing net cost of the railway to taxpayers.

What will change?

The Fife Electrification project will see £311.5 million invested by the Scottish Government to electrify the railway and procure new trains, as part of the next stage in modernising Scotland’s Railway.

Across Fife, we're delivering around 118km of electrified railway, paving the way for the introduction of battery-electric trains, providing greater capacity and reliability as well as more accessible, comfortable, and sustainable journeys.

From the early planning stages through to construction, we've been working hard to deliver this major upgrade that'll bring long-term benefits for rail passengers and the communities we serve.

Work has already begun, and huge progress has been made on electrifying the railway between Haymarket and Dalmeny, the first phase of the project, which includes bridge reconstruction and installation of overhead electric wires.

The electrification will be completed ahead of the arrival of new battery-electric trains.
