Problem

The Line 9 of the Autonomous Government of Valencia Railway communicates the municipalities of and Dénia. The route of this line has about 50 kilometres of rail and goes through the spectacular landscapes of the valencian “” (east coast of ), joining some of the most interesting localities of the two “Marinas”. Along the13 km-length that join the localities of Calpe and Teulada, several slope instability events affected the rail line in this particular stretch, causing in some cases, even the traffic closure. As it can be seen from the pictures, the problem areas to deal with were the following:

• Rocks of several tens of centimetres that have reached the railway platform. • Blocks on the crest slope that risk of failing and reaching the railway track Rocks that have reached the railway platform • Erosion on slopes formed by clay and loamy levels • Accumulation of soil behind the wall protection with the subsuequen need of increasing maintenance.
