Scotland’s first electrified railway upgrade enters new era

Scotland’s first electrified railway upgrade is moving into a major renewal phase. A £20 million programme is now under way to modernise overhead power lines on the historic North Clyde lines.

Scotland’s first electrified railway upgrade targets North Clyde

The work will focus on sections running from Helensburgh, Balloch and Milngavie through Glasgow’s west end and the city’s low-level stations. This part of the network is described as the busiest suburban railway outside London, and it remains one of the most important sections of Scotland’s rail system.

Railway electrification on the route began in 1960, marking a turning point for modern rail travel in Scotland. Electric services now operate on routes including East Kilbride and Barrhead, while further expansion is also taking place in Fife and the Scottish Borders.

Why the overhead power lines need renewal?

Much of the original equipment in and around the North Clyde area is now more than 65 years old. As it nears the end of its working life, renewal has become essential to protect reliability on a route used daily by passengers and communities.

Preparatory work has already begun. Crews are refurbishing the equipment that supports the overhead wires, including cantilevers and other related components that keep the system in place.

Christmas and New Year engineering work planned

The most intensive phase will be the replacement of the wires themselves. This Christmas and New Year engineering work is scheduled across the next three years, with the timing chosen because passenger numbers are lower during that period.

Ross Moran, Route Director at Network Rail Scotland, said the line carries particular historical importance because it was where electrification began in Scotland. He said that change reshaped how people travelled around Glasgow and helped form the railway network used today.

Moran also pointed to the role of the North Clyde lines within the wider system. A single issue in this area can quickly affect services beyond Glasgow, which is why the renewal is being planned now rather than after more serious failures and wider disruption.

The £20 million project is intended to safeguard one of Scotland’s most important suburban rail corridors. By renewing the infrastructure now, Network Rail Scotland aims to keep the route serving passengers and communities well into the future.
