Network Rail is using an unmanned aerial vehicle (UAV) to carry out resilience work on the line between Exeter and Newton Abbot.
The company is performing the work after a portion of the line at Dawlish collapsed into the sea due to extreme weather conditions in 2014.
A study was also conducted to examine the impact of coastal flooding, erosion, and cliff instability on this part of the Great Western route. It is also exploring options available to limit the effects of such natural disasters in the future.
The study identified cliffs at Teignmouth and the Dawlish sea wall as priority areas for resilience work.
Network Rail’s project commercial scheme sponsor Joanna Grew said: "Over the next few weeks, residents are likely to see a lot of activity in the Dawlish and Teignmouth areas as we progress our plans to secure the future of this historic and important part of the Great Western route.
"Securing the future of this line is extremely important to us, which is why we are using the latest technology to build up the most accurate picture of the landscape, how it is likely to change, and what we can do to improve its resilience."
Using the UAV, Network Rail will be able to capture close-up footage of the area faster than traditionally used helicopters. It will keep the company informed about options available to improve resilience in these areas. UAV is much safer and has proved to be less intrusive for the local community, the company said.
