MULTI-MILLION pound works to modernise the railways in North Wales are under way.
More than £10 million is being invested to help upgrade the service between Wrexham and Shrewsbury.
Improvements include strengthening the historic Cefn viaduct and improving a 10-mile stretch of track on the cross-border route.
It is the latest move by the rail network manager to upgrade the railways of Wales and the border counties of England.
Mark Langman, route managing director of Network Rail Wales, said: “This investment across Wales and the border counties of England forms a key part of our modernisation plans to bring the railway across the region into the 21st century.”
Mr Langman's comments came as buses replace trains on the 10-mile line this week.
“It follows recent works to upgrade the railway and station facilities across the area, including upgrades to Chester and Prestatyn stations and new lifts at Wrexham General.
“The next steps in the modernisation programme include our plans to modernise the signalling and control systems between Newport and Shrewsbury and from Flint to Llandudno, starting in 2015.”
He said the changes would deliver improvements for passengers.
“These investments will deliver a real improvement to passengers with the potential for quicker and more frequent journeys on a network that is more resilient and reliable,” he said.
“In addition, a robust railway will also help drive economic growth across the country.”
The improvements include 10 miles of “life-expired” track between Wrexham and Shrewsbury being realigned to reduce noise and create a smoother ride for passengers.
Cefn viaduct will be strengthened with waterproofing works, helping preserve and protect the Grade II listed structure for future generations.
The majority of the work has already been carried out overnight and during weekends.
Currently, the line between Wrexham and Shrewsbury is closed.
The entire programme of work will be completed by the end of September.
l Replacement buses are operating between Wrexham General and Shrewsbury until 5.45am on Monday, September 2.
The buses call at Ruabon, Chirk and Gobowen stations.
