West Coast Main Line upgrade sees 50km of overhead lines replaced in major works

Passengers on the West Coast Main Line are being thanked for their patience following a major programme of engineering work to upgrade key infrastructure in the North West.

Network Rail, working alongside its supply chain partners, has completed the replacement of more than 50 kilometres of overhead line equipment between Preston, Lancaster and Fylde. The work forms part of a wider £400 million investment programme focused on improving reliability along one of the UK’s busiest mixed-use rail corridors.

The upgrades were carried out during an extended period of disruption between Saturday 11 and Sunday 19 April, when passengers travelling on the northern section of the route faced amended services and journey changes.

Alongside the overhead line renewals, signalling improvements were also delivered between Carlisle and the Scottish border, aimed at enhancing performance and resilience across the network.

The investment is designed to support both passenger and freight operations, reducing the likelihood of faults and improving long-term reliability on the route.

Paul Danks, Network Rail senior programme manager, said:

“Upgrading the overhead power systems for trains is vital to keep passenger and freight services running smoothly, and replacing 50kms over an extended railway closure will mean more reliable journeys in future. We know there’s never a good time to close the railway, so we thank those who’ve been impacted by these essential upgrades in Lancashire and Cumbria. It’s all part of our ongoing investment into the West Coast Main Line over the next several years.”
