That might soon change as the Central Railway (CR) has begun testing a new communication technology called Optical Ground Wire (OPGW), which promises to drastically improve mobile connectivity along its entire network.
On September 28, CR General Manager Dharam Veer Meena inaugurated a pilot project at Asangaon, in Thane district. The system has been installed on a 110 kV transmission line, where OPGW cables are strung along the overhead equipment that powers trains.
The system works by combining power line protection with high-capacity fibre optic communication. In simple terms, these cables can carry both electricity and high-speed internet signals, ensuring that calls and data reach passengers’ phones without frequent interruptions.
“OPGW will make railway communication more reliable, speed up projects like Kavach (Automatic Train Protection (ATP) system) and modern signaling, and at the same time improve mobile connectivity for commuters using railway apps or streaming content on trains,” said a senior CR official.
This initiative is part of a broader plan to modernize the Central Railway network and enhance the overall commuting experience. The OPGW technology is expected to not only benefit the daily commuters but also support the implementation of advanced safety features like the Kavach system, which aims to prevent train accidents by providing automatic protection.
The pilot project at Asangaon is a crucial step towards achieving these goals. If successful, the OPGW technology will be rolled out across the entire Central Railway network, bringing a significant improvement in the quality of service for millions of passengers.
For Mumbaiites, this means no more dropped calls, faster ticket booking, and seamless streaming of videos and other content while on the move. The improved connectivity will also facilitate better communication between railway staff, enhancing the overall safety and efficiency of the network.
The Central Railway’s commitment to innovation and modernization is a welcome step for the city’s commuters. As the pilot project progresses, the hope is that the benefits will be felt across the network, making daily travel more convenient and enjoyable for everyone.
