India’s railway network is preparing for a major technology and infrastructure upgrade. Indian Railways has sanctioned projects worth over ₹765 crore aimed at strengthening electric traction systems and expanding digital communication networks across several critical corridors.
The approvals cover two major traction upgrades on high-density freight and passenger routes, along with a large-scale expansion of the optical fibre communication backbone in western India. Together, these projects are designed to improve train speeds, increase freight capacity, and support advanced railway safety technologies.
Powering a key freight corridor on the East Coast
The project will replace the existing 1×25 kV electric traction system with the more advanced 2×25 kV system, which provides higher power supply capacity to trains. This change allows railways to run heavier freight trains and maintain higher speeds while improving operational reliability.
The section lies on the crucial Howrah–Chennai main line, one of the busiest rail corridors in the country. It plays a central role in transporting minerals and industrial goods from Odisha and Chhattisgarh to Visakhapatnam Port, making it a vital freight artery for eastern India.
Strengthening traction power along this stretch is expected to ease congestion and enable smoother freight movement while also benefiting passenger services.
Boosting capacity on the Mumbai–Chennai route
The upgrade, sanctioned at ₹259.39 crore, will also convert the existing traction system from 1×25 kV to 2×25 kV. This enhancement will allow the corridor to handle heavier train loads, improve operational reliability, and increase the speed potential of both passenger and freight trains.
The section forms part of the busy Mumbai–Chennai railway route, connecting major industrial regions and ports. Strengthening the traction network here is expected to facilitate smoother freight operations and support faster passenger services, including modern trains such as Vande Bharat Express.
The project also contributes to Indian Railways’ broader goal of reaching 3,000 million tonnes (MT) of annual freight loading in the coming years.
Building the digital backbone for railway safety
Alongside traction upgrades, the railways are strengthening their communication infrastructure with a ₹187.88 crore optical fibre network project across the Western Railway.
The project will establish a 4×48 core Optical Fibre Cable (OFC) backbone architecture across the Vadodara and Mumbai Central divisions. This system will deliver higher bandwidth, improved redundancy, and reliable connectivity for railway communication networks.
Under the project, fibre cables will be laid across 1,000 route kilometres, including:
-
692 km in Vadodara Division
-
308 km in Mumbai Division
The digital backbone is critical for supporting Kavach, the indigenous train protection system being rolled out across the national railway network. Kavach relies on robust communication infrastructure to enable real-time train monitoring and automatic braking in case of potential collisions.
Infrastructure for a high-capacity railway network
These three projects form part of a broader modernisation programme included in the 2024–25 Railway Budget, aimed at upgrading traction power systems and expanding digital infrastructure across the country.
Together, the initiatives highlight Indian Railways’ dual strategy: increasing physical capacity through stronger traction systems while simultaneously building the digital backbone needed for modern signalling and safety technologies.
For a network that carries over a billion tonnes of freight annually and connects thousands of cities and industrial clusters, such investments are essential to keep pace with India’s rapidly growing logistics and mobility demands.
