Explanation:

TRI-NETRA is abbreviation for Terrain Imaging for Drivers Infrared, Enhanced, Optical & Radar Assisted system.

• It comprises of infrared camera, optical camera and radar assisted imaging system for assisting loco pilots in identifying obstructions on tracks, mainly in foggy conditions.
• This device is making an attempt during fog via ultrasonic waves by help of which it will be able to detect any obstruction on tracks.
• The field trials being undertaken is for proof of concept and its testing on all parameters will be done after its procurement.

Indian Railways is conducting extensive trials of Tri-Netra technology so as to be sure that it is perfect in detecting any obstruction on tracks during fog.
