Indian Railways is now gearing up to commission the Kavach 4.0 safety system on various routes throughout the country within a short span of six years. Over 30,000 people have already been trained on Kavach systems, the Railways said

In a major push towards modernisation and passenger safety, the Indian Railways has commissioned the indigenous Kavach 4.0 safety system on the Mathura-Kota section of the high-density Delhi-Mumbai route.
Speaking on the development, Railway Minister Ashwini Vaishnaw said, “Railways has indigenously designed, developed, and manufactured the Kavach Automatic Train Protection System, taking inspiration from Hon’ble PM Shri Narendra Modi Ji’s ‘Atmanirbhar Bharat’ vision. Kavach 4.0 is a technology-intensive system. It was approved by the Research Designs & Standards Organisation (RDSO) in July 2024. Many developed nations took 20-30 years to develop and install train protection systems. The commissioning of Kavach 4.0 on the Kota-Mathura section has been achieved in a very short timeframe. This is a very big achievement.”

Advanced train protection systems of international standard were not installed in the country for 60 years after independence.
Indian Railways is now gearing up to commission the Kavach 4.0 safety system on various routes throughout the country within a short span of six years. Over 30,000 people have already been trained on Kavach systems. IRISET (Indian Railway Institute of Signal Engineering and Telecommunications) has signed a Memorandum of Understanding (MoU) with 17 All India Council for Technical Education (AICTE)-approved engineering colleges, institutions, universities for incorporating Kavach as part of their BTech course curriculum.
Kavach will help the loco pilots in maintaining train speed by effective brake application. Even in low visibility conditions such as fog, the loco pilots will not have to look outside from the cabin for a signal. Pilots can see the information on the dashboard installed inside the cab.
What is Kavach?
An indigenously developed train safety system, Kavach is designed to prevent accidents by monitoring and controlling train speeds.
It is designed at Safety Integrity Level 4 (SIL 4) – the highest level of safety design.
Its development started 10 years ago and the system was extensively tested for over three years.
After technical improvements, the system was installed in South Central Railway (SCR). The first operational certificate was granted in 2018.
Based on the experiences gained in SCR, an advanced version ‘Kavach 4.0’ was developed. It was approved in May for speeds up to 160 kmph.
Indian Railways invests more than Rs 1 lakh crore per year on safety-related activities.
