Engineers are investigating how to repair the damaged sea wall at Shakespeare Beach, Dover.
Storms have created sink holes in the wall, forcing the closure of the railway line between Dover and Folkestone.
Workers from Network Rail and Costain are digging up the tracks to examine how the wall was built. Limited records were held during the wall’s construction in 1927, making the work a more challenging process.
The line has been closed since Christmas 2015, with replacement bus services in operation.
