Landslip repair should see Kyle Line reopen for Easter

WORK IS under way to stabilise two large landslides that closed the Kyle Line railway near Stromeferry in north west Scotland in October.

The failures were triggered by prolonged heavy rainfall.

Both were at the toe of steep hillsides several hundred metres high, and the debris from one of them struck a passenger service travelling between Kyle of Lochalsh and Inverness.

Edmund Nuttall and Donaldson Associates were asked to assess the landslides and suggest remediation options. These included insitu slope support, retaining walls, slope regrading and realignment of the railway away from the failures.

A detailed assessment showed the safest, most feasible solution was to realign the railway.

This involved building a 400m long, 7m high causeway on the tidal shore of Loch Carron for the new section of track to run on. A 15m high buttress was built at the toe of the hillside to protect the track from further slides.

The £2M project involves placing 50,000t of rockfill from quarries on the Isle of Skye and at Dingwall, together with more than 10,000t of armour stone from Oban and Inverness for coastal protection.

Huesker UK has supplied more than 20,000m 2of HaTe separator geotextile and Comtrac and Stabilenka high strength geotextile reinforcement for the structure.

Detailed design and planning was undertaken by the Nuttall/ Donaldson project team in December and construction work began last month. The railway is scheduled to reopen by Easter.
