Railway Minister Ashwini Vaishnaw informed the Lok Sabha on December 18, 2025 that the indigenously developed KAVACH (Automatic Train Protection — ATP) system has been fully commissioned on over 2,000 km of the Indian Railways network. KAVACH automatically applies brakes to prevent collisions and over-speeding. The Ministry reported that consequential train accidents have been reduced from 135 in 2014 to just 11 now — a reduction of approximately 90%. On the infrastructure front, 7,129 km of optical fibre cable has been laid and 860 telecom towers installed. Trackside equipment has been fitted along 3,413 km while KAVACH systems have been installed on 4,154 locomotives. Nearly 40,000 technicians and operators have been trained. KAVACH holds SIL-4 (Safety Integrity Level-4) certification, the highest safety rating. The system is being progressively extended on high-density routes including the Delhi–Mumbai and Delhi–Kolkata corridors. India has also begun exporting the KAVACH technology, signalling its emergence as a railway safety technology provider.

Frequently asked questions
On how many kilometres of the Indian Railways network has the KAVACH Automatic Train Protection system been commissioned?
KAVACH has been commissioned on over 2,000 km of the Indian Railways network, as informed by Railway Minister Ashwini Vaishnaw in the Lok Sabha on December 18, 2025.
By what percentage have consequential train accidents been reduced since 2014 following the deployment of KAVACH?
Consequential train accidents have been reduced by approximately 90%, falling from 135 in 2014 to just 11, largely attributed to safety infrastructure improvements including KAVACH.
What safety certification does the KAVACH system hold and what is its significance?
KAVACH holds SIL-4 (Safety Integrity Level-4) certification, which is the highest international safety rating for railway protection systems.
How many locomotives have been equipped with KAVACH and how many technicians have been trained to operate it?
KAVACH has been installed on 4,154 locomotives, and 40,000 technicians have been trained for its operations and maintenance.
What is the primary function of the KAVACH Automatic Train Protection system?
KAVACH automatically applies brakes to prevent train collisions and over-speeding. It is an indigenously developed system that enhances railway safety through real-time signalling and speed monitoring.
