The Indian Railways will use radio-frequency identification tags (RFID) for tracking of wagons, coaches and locomotives to ensure effective and transparent functioning. <br/><br/>A senior Railway Ministry official said the public transporter has issued instructions for equipping all wagons with RFID tags to begin with. Using RFID devices, it will be easier for the railways to know the exact position of wagons, locomotives and coaches.<br/><br/>The official said, currently, such data is maintained manually, which leaves scope for errors. Railways have sanctioned 57 crore rupees for the first phase of roll-out of the system. Railways had implemented the RFID system on the Vishakhapatnam-Talcher-Paradeep section as a pilot project.
