Hyderabad-based company HBL Engineering Limited, formerly known as HBL Power Systems Limited, has secured a significant contract valued at ₹132.95 crore from South Central Railway for the deployment of the indigenously developed Kavach safety system.
The project consists of implementation of the Kavach safety system across the Vijayawada–Ballarshah section, marking a major step forward in enhancing railway safety and accident prevention in the region.
The contract covers installation of Kavach over a 446-kilometre stretch, across 48 stations and 10 locomotives. The project is expected to be completed within 18 months, according to a stock exchange filing.
Kavach, an automatic train protection system developed in India, aims to reduce the risk of signal passing at danger (SPAD) and collisions. It is part of Indian Railways’ broader push to enhance safety through advanced technology and indigenous innovation.
In a parallel development, the company also received a letter of acceptance from South Central Railway for upgrading Kavach from Version 3.2 to Version 4.0 along the Mudkhed (including)–Manmad (excluding) section. The ₹30.67 crore contract, inclusive of GST, covers 350 kilometres and is to be executed within 24 months.
