Bhopal Yard Gets Fibre-Optic Rail Signal Upgrade

16 May 2025 CW Team

The Bhopal Division of West Central Railway has begun operating a state-of-the-art fibre-optic-based signalling system at the strategically important Nishatpura yard—marking a key step in India’s transition to smart and resilient rail infrastructure.

Replacing traditional copper wiring, the new system offers real-time digital communication between the control centre and trackside signals. It is expected to significantly enhance safety, operational reliability, and energy efficiency—especially critical in high-traffic areas such as Bhopal, where both industrial freight and passenger movement are heavy.

At the core of the upgrade is the Lamp Output Module (LOM), a digital interface that delivers instantaneous signal commands via optical fibre lines. The system includes built-in redundancy: should the main line fail, an auxiliary connection takes over without delay, ensuring uninterrupted visual signalling. Other features include an automatic temperature control mechanism, where cooling fans activate only as required to protect components—minimising maintenance and prolonging service life.

Fibre-based signalling also reduces dependence on copper—a resource-intensive material—and supports longer transmission distances with minimal interference. This aligns with Indian Railways’ broader shift towards low-carbon, digital-first operations. The initiative dovetails with the national goal of carbon neutrality by 2070 and is a part of Indian Railways’ push for modern, climate-smart public transport.

The Nishatpura yard pilot is now set to expand to the Bhopal–Bina corridor, with phased deployment targeted for completion by June 2026. Once operational, it is expected to increase signalling precision, improve passenger safety, and optimise freight logistics across central India. As Indian Railways continues to modernise, the fibre-optic upgrade stands as a benchmark in efficient, green railway transformation.
