What is the Gajraj System?

• It  is built to use the existing optical fiber cable (OFC) as sensors to identify elephant movements near railway tracks and alert locations to station masters, loco pilots, and control offices. 
• The Indian Railways has chosen the Northeast Frontier Railways to pilot this program and implement this new, cutting-edge technology in some of the worst affected areas.

How does the Gajraj system work?

• Every time an elephant steps onto the track, the system alerts the train controller, station master, train drivers, and other stakeholders who take precautionary measures to avoid imminent danger.
• A real-time alarm is generated when a movement is detected.
