WEST COAST MAINLINE TO RE-OPEN NEXT MONDAY

Train services will resume running over flood-damaged Lamington Viaduct on Monday, February 22.

Works to repair and reopen the viaduct, on the West Coast Mainline, are to finish ahead of schedule following an intensive seven week engineering project to save the vital structure from collapse.

The Victorian-built viaduct had been severely weakened and left close to falling into the River Clyde by flood damage caused by Storm Frank on New Year’s Eve.

The viaduct’s second pier was left on the brink of failure when floodwaters scoured out much of its foundations.

Phil Verster, managing director for the ScotRail Alliance, said: “I am delighted that we have managed to complete the works at Lamington ahead of schedule.

“I understand the impact the closure of Lamington Viaduct has had on customers and our engineers have been working around-the-clock since its closure to finish the repairs and get trains back on the West Coast Mainline.

“This project has been a hugely challenging one - involving working out in the Clyde through the worst of January's storms in a race against time to save the structure. Our engineers have faced atrocious conditions throughout this project and I am really proud of their hard work and their absolute commitment to getting the line open again.

“I really do want to thank customers for their patience and our industry partners for the close cooperation shown over the last two months. By working together we have been able to help limit disruption for passengers by providing diversionary routes for many of the affected services.”

Engineers had to work around-the-clock to divert the Clyde and stabilise the structure following Storm Frank.

The incident also damaged the second pier’s steel bearings, which support the bridge-deck and track above the pier, a non-load-bearing section of the viaduct’s third pier and the structure’s north abutment.

Over the weekend, engineers installed new steel bearings on the viaduct’s damaged second pier and constructed a new concrete plinth on the top of the pier to support them.

Having successfully raised the bridge-deck back into position last week, the recovery works are now progressing two weeks ahead of the March reopening date previously announced.

Engineers have taken advantage of a break in the weather conditions and the earlier than expected arrival of the new, custom-made, bearings to accelerate their recovery programme.

Stewart MacPherson, route delivery director for Scotland, said: “January’s persistent poor weather was a real challenge for the team in terms of safely accessing and stabilising the viaduct, but the drier weather since the start of February has given us the opportunity to accelerate the programme and we achieved the crucial milestone of jacking the bridge deck back into its original position at the tail end of last week.

“The location and age of the structure have made this a very complex piece of engineering work and has required input from specialist divers, engineers and hydrologists throughout the repairs. Work will continue on the viaduct 24/7 for the next week ahead of the line re-opening on Monday 22nd February, with the team focussing on the removal of the jacks and repositioning the bridge-deck on to the newly installed bearings. It’s been a fantastic response from the team in very challenging conditions and my thanks go to all involved.”
