West Central Railway’s Bhopal division has achieved a major milestone by implementing a state-of-the-art signal control technology that operates entirely on optical fibre at its Nishatpura yard, effectively replacing the traditional wiring system
Senior Divisional Commercial Manager Saurabh Kataria indicated that this cutting-edge technology has recently been commissioned on two signal posts within the Nishatpura yard.
About the New Signal Technology
The newly deployed system utilises optical fibre cables, which enable faster, more secure, and highly reliable signal transmission in comparison to conventional methods. The fundamental component of this upgrade is the ‘Lamp Output Module’ (LOM), which transmits signal commands directly from the control room to the signal posts via optical fibre.
This innovative approach allows for signal management along the railway track to occur directly through fibre lines rather than through conventional wiring. Importantly, even in the event of a component failure, the signal remains visible to approaching trains.
The system also incorporates an automatic cooling fan that activates as necessary to prevent equipment overheating. In the case of a failure in the primary fibre line, an auxiliary line immediately assumes responsibility, guaranteeing uninterrupted service.
Future Projection
A phased implementation has commenced along the Bhopal-Bina railway section. According to current plans, the entire section is anticipated to be fully upgraded with this new system by June 2026.
