Rail journeys on the West Coast Main Line are now more reliable after a once-in-a-generation overhaul of the signalling system in Carlisle.
Network Rail has invested £61 million into the Kingmoor resignalling project to modernise 1960s systems and replace them with newer technology.
The work, which began in April 2025 and has been delivered by principal contractor Siemens Mobility, has seen:
- 26 lightweight LED signal heads replacing traditional bulbs
- New detection systems to monitor train movements
- Upgrades to track and points for the new systems
- Overhaul of signalling power supplies
- New control panels installed for signallers in Carlisle signal box
- Digital operating systems installed in the signal box relay room
- Upgraded CCTV at Floriston level crossing
On Wednesday 7 January, all systems went live after a seven-day closure of the line between Carlisle and Lockerbie for final installation, testing and commissioning.
Passengers impacted by the New Year closure are being thanked for their patience while this essential work to bring the new systems online was completed.
Christian Irwin OBE, Network Rail Capital Delivery director for the North West and Central region, said: “Today is the start of a new era for the way we signal freight and passenger trains through Carlisle and north into Scotland. This major investment, using the latest technology, benefits both passengers and freight, getting people and goods to where they need to be more smoothly and reliably on this crucial section of railway.
“We know this has brought disruption for passengers at the start of 2026, and we’d like to thank you for bearing with us while we made these essential upgrades, which will improve journeys for years to come.”
Matt Kent, director of operations and manufacturing, rail infrastructure at Siemens Mobility UK&I, commented: “We are proud to have partnered with Network Rail to successfully deliver the Kingmoor resignalling project, a key milestone in our mission to transform rail travel and transport on the West Coast Main Line.
“This extensive signalling upgrade includes state-of-the-art digital trackside equipment, fully compatible with European Train Control System (ETCS) standards to enable future integration. These enhancements will help future-proof the line, delivering enhanced reliability and efficiency for both passengers and freight.”
