Kernex Microsystems shares hit a record high after commissioning its Kavach Version 4.0 system on the 207 km Tundla–Panki Dham section, taking its executed Kavach network on North Central Railway to 572 route kilometres.
Kernex Microsystems India share price hit a fresh all-time high of ₹2,419.90 on July 3, 2026, up over 0.4% for the day. The stock opened at ₹2,312.00, touched an intraday high of ₹2,419.90 and recorded a low of ₹2,368 during the session. Trading volume stood at 7.8 lakh shares compared with the 30-day average volume of 4.16 lakh shares.
The move came after the company announced the successful commissioning of its Kavach Version 4.0 automatic train protection system on a significant stretch of North Central Railway. YTD, the stock has gained nearly 98%, showing sustained investor interest in the company.
Kernex Microsystems India Ltd informed that its Kavach Version 4.0 system has been successfully commissioned on the 207 km Tundla–Panki Dham section of North Central Railway.
Kavach, which stands for Train Collision Avoidance System (TCAS), is an indigenously developed automatic train protection system that prevents train collisions by automatically applying brakes when a risk of collision is detected. It carries a Safety Integrity Level 4 (SIL-4) certification, which is the highest functional safety classification for railway signalling systems.
As reported by Indian Railways, the commissioned system supports train operations at speeds of up to 130 kmph on the newly added 207 route kilometres. With this addition, the total Kavach Version 4.0 coverage on North Central Railway has risen to 652 route kilometres. Of these, 572 route kilometres have been executed by Kernex.
The commissioning involved successful trial runs using the Kanpur Shatabdi Express and Sikkim Mahananda Express, both equipped with the Kernex-built Kavach system. A notable aspect of the project was its integration with the Hitachi Electronic Interlocking System. As per the company, this integration was completed without any operational issues, confirming that the system can work alongside existing infrastructure from third-party technology providers.
The project scope was substantial. It covered Kavach installations at 39 stations, commissioning of 10 WAP-7 locomotives, installation of more than 4,600 Radio Frequency Identification (RFID) tags, construction of 17 communication towers, laying of 48-core optical fibre cable and establishment of 30 dedicated equipment rooms.
Before commissioning, the system underwent extensive testing and validation by the Research Designs and Standards Organisation (RDSO), North Central Railway and an Independent Safety Assessment (ISA) conducted by Italcertifier, Italy. These validations are mandatory requirements before any Kavach deployment can go live on the Indian rail network.
The company's announcement further noted that its Kavach Version 4.0 system has demonstrated support for train operations at speeds of up to 160 kmph over an executed section of 175 route kilometres. This indicates the system's readiness for higher-speed rail corridors, which may form part of India's broader rail modernisation plans going ahead.
The commissioning adds to Kernex's growing portfolio of executed Kavach deployments and strengthens its documented track record of large-scale project delivery. This could work in the company's favour when bidding for future contracts from Indian Railways and its various zonal divisions. Kernex has already built a sizeable order book in recent months, including a contract valued at ₹2,041.40 crore from Chittaranjan Locomotive Works (CLW).
Kernex Microsystems India Ltd was incorporated in 1991 and is headquartered in Hyderabad. The company specialises in the manufacture and sale of safety systems and software services for railways in India and in select international markets. Its flagship product, Kavach, is one of the few SIL-4-certified automatic train protection systems developed domestically. Alongside Kavach, its product portfolio includes LxGuard, a level crossing protection system; TrainSHIELD, a train collision avoidance system; KMDAX, a multisection digital axle counter; and CASRY, a collision avoidance system for railyards, among others.
The successful commissioning of Kavach Version 4.0 on the 207 km Tundla–Panki Dham section adds to Kernex Microsystems' cumulative execution record, taking its total deployed coverage to 572 route kilometres out of 652 route kilometres on North Central Railway. The project's seamless integration with third-party interlocking infrastructure and its demonstrated readiness for higher-speed operations are notable from an execution standpoint. With a healthy order book and sustained delivery progress, the company continues to occupy a significant position in India's railway safety infrastructure programme.
