Network Rail has started a £20 million programme to renew overhead power lines on Scotland’s original electrified railway, focusing on sections of the North Clyde lines between Helensburgh, Balloch, Milngavie, and Glasgow’s low-level stations

Much of the original overhead line equipment in the North Clyde area is now more than 65 years old and nearing the end of its operational life. Network Rail said the upgrade is essential to maintain safe and reliable services.

Introduced in 1960, the North Clyde electrification marked the beginning of modern electric rail travel in Scotland. Today, electric services operate on routes including East Kilbride and Barrhead, with further expansion continuing in Fife and the Scottish Borders.

Preparatory work is currently underway, including the refurbishment of supporting structures. More intensive engineering work to replace the overhead wires will take place during Christmas and New Year engineering possessions over the next three years, when lower passenger numbers reduce disruption.

“This stretch of railway was where electrification began in Scotland and marked a real turning point. It changed how people travelled around Glasgow and helped shape the network we use today. We know how vital this area is to the railway as a whole. A single issue on the North Clyde can quickly affect services well beyond Glasgow, which is why this work is being planned now rather than waiting for more serious failures and wider disruption later. 

“This project is about looking after the railway that people rely on every day. By renewing it now, we are helping to make sure it continues to serve passengers and communities long into the future.” 

Ross Moran, route director at Network Rail Scotland.
