Kernex Microsystems Commissions Kavach 4.0 on North Central Railway

HYDERABAD, India — Kernex Microsystems (India) Ltd has successfully commissioned the upgraded Kavach Version 4.0 safety system along a 207-kilometer stretch of the North Central Railway (NCR). The announcement, made on July 2, 2026, confirms the deployment of the advanced Automatic Train Protection (ATP) technology on the vital Tundla-Panki Dham section, further cementing the company's role in the Indian Railways' safety infrastructure rollout.

This milestone represents a significant expansion of the Kavach network, which is designed to prevent train collisions through an automatic braking system. The newly commissioned corridor is part of a broader push to modernize high-density railway routes across the country.

Scaling Indigenous Safety Infrastructure

According to the official regulatory filing submitted by Kernex Microsystems to the National Stock Exchange (NSE), the implementation of Kavach Version 4.0 now covers 652 route kilometers within the North Central Railway. Of this total coverage, Kernex has executed the installation across 572 route kilometers, establishing the firm as a primary technology partner in the region.

The upgraded system is engineered to support train speeds of up to 130 kmph, with successful tests conducted on major passenger lines, including the Kanpur Shatabdi Express and the Sikkim Mahananda Express. Furthermore, the company reported that its version of the Kavach system has successfully demonstrated operational stability at speeds up to 160 kmph during testing over a 175-kilometer section, signaling potential readiness for high-speed rail integration.

Technical Milestones and Interoperability

The project involved a complex integration of hardware and software components to ensure the system functions seamlessly within the existing railway environment. Key technical accomplishments highlighted by the company include:

• Integration: Successful synchronization with the Hitachi Electronic Interlocking System, confirming interoperability between indigenous and established signaling technologies.

• Infrastructure: Installation of Kavach systems across 39 stations and the commissioning of 10 WAP-7 locomotives.

• Backbone Development: Construction of 17 dedicated communication towers, the laying of 48-core optical fiber cables, and the establishment of 30 equipment rooms to support the signal network.

• RFID Implementation: Installation of more than 4,600 RFID tags along the tracks to provide real-time location and safety data to locomotive pilots.

Rigorous Validation Process

Before final commissioning, the technology underwent comprehensive evaluation. The system was validated by the Research Designs and Standards Organisation (RDSO), the research wing of the Indian Railways, and the North Central Railway authorities. Additionally, an Independent Safety Assessment (ISA) was conducted by Italy-based firm Italcertifier to ensure the system meets global safety benchmarks.

Why It Matters

For the Indian Railways, the wider adoption of the Kavach system is a high-priority initiative aimed at enhancing passenger safety on busy trunk routes. For travelers, the expansion of these systems translates to a more reliable and secure transit experience, particularly on high-traffic lines like the Delhi-Howrah route. For investors, Kernex’s successful delivery of large-scale, technically complex projects on time strengthens its standing in a competitive market as the government continues to invest in nationwide safety upgrades.
