In 2025, Indian Railways is advancing its safety measures by implementing the Kavach system. This Automatic Train Protection System aims to enhance train safety and operational efficiency. The initiative involves the installation of Kavach on 10,000 locomotives across India. Notably, this implementation will proceed without waiting for ground equipment. Instead, it will leverage the loco-to-loco communication feature of the Radio Communication Backbone known as ‘MComm’.
Background of Kavach
Kavach was recommended by a high-level safety review committee in 2012. The committee was led by renowned figures like Anil Kakodkar and E. Sreedharan. Their focus was on adopting a radio-based Train Control System to improve safety and increase train frequency on existing infrastructure.
Development of MComm
MComm is a critical component of Kavach. It was developed by railway engineer Lalit Mansukhani at the Research Design & Standards Organisation (RDSO). The system was designed to provide a robust radio communication solution that does not rely on outdated mobile technologies like 2G or 4G LTE. MComm is scalable and requires minimal hardware, making it a cost-effective solution.
Proof of Concept and Trials
The first proof-of-concept trials for Kavach occurred in 2012 on the Vikarabad-Wadi section of South Central Railway. These trials demonstrated the system’s ability to stop a freight train from violating a red signal. Subsequent trials confirmed Kavach’s effectiveness in automatic signalling, prompting its consideration for major routes across India.
Implementation Challenges
Despite initial successes, the rollout of Kavach faced delays. Issues included technical mismatches related to antenna bandwidth and radio frequency. However, these challenges have been addressed, allowing for a renewed focus on expanding Kavach’s reach.
Current Status and Future Plans
As of 2025, Indian Railways is actively tendering for the installation of Kavach on 10,000 locomotives. Additionally, the rollout of Ground Kavach equipment is planned for 15,000 route-kilometres. Key routes, including Chennai-Mumbai and Chennai-Delhi, are prioritised for these upgrades. The involvement of multiple firms in the installation process indicates a collaborative approach to enhancing railway safety.
Significance of Kavach
Kavach represents leap forward in railway safety technology in India. By utilising indigenous technology, it aims to reduce accidents and improve operational efficiency. The system’s capability to function without complete infrastructure showcases the innovative spirit within Indian Railways.
