‘Raksha Dhaga’ or literally, ‘Safety Thread’, is a device pioneered by Konkan Railways in landslide-prone areas. It consists of a wire attached to sensors which can be tripped when the wire is moved excessively or snapped by a falling rock. The sensors when tripped activate lights and hooters 0.5km away so that approaching trains can safely stop before the location of the landslide. These are used in several stretches on the KR route in cuttings and in unlined tunnels.

In addition, KR has pioneered the use of electronic inclinometers to detect earth slippages in areas prone to landslides, connected to a similar warning system as in the Raksha Dhaga.
