Video footage shows the enormous operation launched after a landslip caused by heavy rain.
Thousands of tonnes of earth had to be moved to secure the area after the landslip at Hillmorton Junction, just outside Rugby, which was caused by Storm Christoph.
The operation took more than two weeks.
MP for Rugby Mark Pawsey was invited out to visit the site and shown the work that was carried out by Network Rail Engineers.
He described the operation as “very impressive”.
As reported, the landslip was spotted at the end of January, after a worker noticed “something unusual”.
Trains were cancelled, with buses put on as a replacement between Rugby and Stafford until the area could be made secure.
Work is now complete and services are set to revert to the previous timetable from tomorrow, Saturday, February 13.
What work was carried out?
The work included moving thousands of tonnes of earth on the West Coast Main Line after the landslip was spotted on the embankment at Hillmorton, near Rugby.
The embankment was rebuilt and 10,000 tonnes of new stone was laid to improve drainage.
New foundations were also installed, along with special pins to prevent future movement.
Landslip was “spotted early”
Ellen Wintle, infrastructure director for Network Rail ’s West Coast South route, said: “I’m really proud of my team for working all hours to get this vital section of the West Coast Main Line secure and back up and running again for our passenger and freight customers.
“Because this landslip was spotted early we were able to control the damage and carry out repairs quickly, reducing the length of time passengers and freight would be disrupted.
“I thank people whose essential journeys were slightly longer during the work for their patience while we worked tireless to make the railway safe and secure again.”
Mr Pawsey added: “As someone who regularly uses the railway to travel between Rugby and London, I was keen to visit the site of the landslip and see for myself the progress being made to resolve this issue.
“It’s very impressive to see how swiftly Network Rail’s team have been able to restore the embankment, especially in the very challenging weather conditions of recent days.”
