Indian Railways in an effort to maintain and keep a check on its 3, 50,000 wagons will be putting RFID tag in its coaches. The railways carry about 23 million passengers per day and over 3 million tons of freight every day over 65000 route kilometers. The project will be completed by 2021 and will cost ₹112.96 crore according to a senior railway official. Till now approximately 22,000 wagons and 1200 coaches have been fitted with radio-frequency identification (RFID) tags, said Rajesh Agarwal, member, Rolling Stock, Railway Board. The RFID project undertaken by CRIS, the IT arm of Indian Railways, can read data even at a speed of 182 kmph, Agarwal said. The RFID is a technology where an antenna broadcasts energy to the tag, which in turn returns the modulated energy back in the form of back-scatter. A RFID reader is a device used to gather information from an RFID tag, which is used to track individual objects. The complete solution also includes the integration of RFID readers with various equipment such as Train Presence Detectors (TPDs), trackside condition monitoring equipment etc. The combination of all of these allows for an early identification of rolling stock that may ...
