STATE-OF-THE-ART UPGRADATION PLAN IN BLUE LINE OF METRO RAILWAY
Kolkata, Date- 29.11.2025
Metro Railway Kolkata is India’s first and Asia’s fifth Metro Railway network. It was built and commissioned with state-of-the-art technology then available in 70s. Whenever and whatever technological upgrades, automations have evolved the same has been continuously incorporated in Metro Railway Kolkata in Blue Line and in all other new Corridors.
For ensuring improved reliability and passenger safety in Metro Railway Kolkata, as a part of its futuristic plan, Building Management System (BMS) is being implemented at each station of Blue Line to facilitate centralized control of all systems, including platform AC, tunnel ventilation, lifts, escalators and sump pumps. This initiative will pave the way for remote monitoring and control of all electrical assets and temperatures from the central location of Metro Rail Bhavan.
According to this plan, five stations each will be grouped together as a cluster and all the assets of such cluster of stations (five each) will be monitored from one monitoring centre located at a particular station among these five stations. Activities of all such monitoring centres will finally be supervised/controlled on real time basis from the Metro Rail Bhavan Control Room.
The ambient temperature of stations will be controlled at the desired level automatically without any human intervention and any rising temperature either in the tunnel or in the platform will be communicated to the control automatically with a buzzer sound. Whenever there will be a rise in temperature in the tunnel or rise in sub-soil temperature or fire in the tunnel or congestion of train inside the tunnel then automatically ventilation fan will start to operate on its own.
