A £61m project to upgrade a train signalling system has been completed, on a route which is undergoing a series of upgrades.
The Kingmoor resignalling project on the West Coast Main Line at Carlisle, in Cumbria, has seen 1960s systems modernised, including brighter signal lights and new systems, Network Rail said.
Work began in April, but went live after a seven-day closure of the line between Carlisle and Lockerbie for “final installation, testing and commissioning”.
It is as the line between Preston and Carlisle is also closed for the demolition and replacement of the Clifton railway bridge, which is expected to reopen on 15 January.
