Work that will pave the way for the electrification of the Fife Circle line is about to get under way.

The £55m Scottish government investment in the line between Haymarket and Dalmeny will see the railway transformed to accommodate quieter, more environmentally friendly electric trains.

The first phase of work between Haymarket and Dalmeny will see Network Rail pile the foundations for masts that will carry overhead wires up to the Forth Bridge. In total it will see 25 single track kilometres (STKs) of railway electrified by December 2024.

Subsequent phases of work will see partial electrification of lines in Fife – totalling a further 104 STKs, to enable the introduction of Battery Electric Multiple Units (BEMUs) to replace life-expired diesel units which will be phased out.

Contractors Scottish Powerlines (SPL) will shortly begin on-site activities between Haymarket and Dalmeny – including piling and constructing steelwork foundations to support overhead power masts.

Electrification from Edinburgh into Fife represents the next phase of the rolling programme of electrification and part of the wider programme of decarbonisation to build a cleaner, greener Scotland’s Railway.

Alex Hynes, managing director of Scotland’s Railway, said: “We’re working hard alongside the Scottish government to bring the benefits of electrification to communities across Scotland. The government has set an ambitious target to decarbonise our railway and projects such as the electrification of the Fife Circle – starting with the line connecting Fife to Edinburgh, will be key to delivering on that commitment.

“We look forward to delivering further investment in Scotland’s Railway and significantly improving the quality of service for the communities it serves. This is one of a number of projects that will create an even greener, cleaner, and more reliable railway for Scotland.”

Scottish government transport minister Jenny Gilruth added: “It’s great news that the first phase of the Fife electrification project is getting under way as this will make a significant difference to passenger and freight services in the future. It will also help towards the delivery of our Rail Decarbonisation Action Plan which will see removal of all diesel trains on passenger services by 2035.”
