In a Tuesday filing to the stock exchanges, the company stated: “HBL received approval from the Research Designs and Standards Organization (RDSO) for Version 4.0 of the Kavach System. HBL is the first company to receive this approval.”

This approval reaffirms HBL’s leadership in the Automatic Train Protection (ATP) segment and enables the company to commence deliveries for an accumulated order book of ₹3,763.83 crore related to Kavach. The company expects to fulfil these deliveries within 24 months. This is a critical step in the company’s ongoing efforts to capitalise on the Indian government’s push for safer, more efficient railways. (Source: LiveMint)

What is Kavach?

Kavach, known as the Train Collision Avoidance System (TCAS) or IRATPS, is India’s indigenous Automatic Train Protection system. Launched in 2020, the system uses GPS and RF communication to detect potential collisions and can automatically apply brakes if the loco pilot fails to respond. In addition to collision prevention, Kavach systems ensure speed regulation, signal compliance, and loco-to-loco communication, making it a holistic safety mechanism. It is a key component in modernising India’s railway safety infrastructure and is expected to be deployed across over 44,000 kilometres of railway lines by 2030.
