Dingle Site, now known as Dingle Curve, was a Deviation construction site started in the summer of 1969 beyond Barn site, the two of which now form Barn Cutting. The two were joined in late August 1970.
There is a particularly elegant pair of dry stone sheep creep portals under the line at this point, built by one of the Deviationists.
