The Ministry of Railways on 17 July 2016 developed the TRI-NETRA system on locomotives for enhancing the vision of Locomotive Pilots in inclement weather. TRI-NETRA stands for Terrain imaging for diesel dRivers INfra-red, Enhanced opTical &Radar Assisted system.
TRI-NETRA system is be made up of high-resolution optical video camera, high sensitivity infra-red video camera and additionally a radar-based terrain mapping system. These three components of the system act as three eyes (Tri-Netra) of the Locomotive Pilot.
Highlights of the TRI-NETRA system
• TRI-NETRA is designed to see the terrain ahead of the running locomotive during inclement weather by combining the images captured by the three sub-systems.
• It will create a composite video image which shall be displayed in front of the Loco Pilot on a computer monitor.
• It will give the locomotive pilot a clear view of the track ahead in bad visibility conditions so that he can apply brakes well in time.
• *It will also map the terrain ahead so that the driver knows when he is approaching a station or a signal.
Concept of TRI-NETRA
The concept of TRI-NETRA was developed by Development Cell under the guidance of Member Mechanical, Railway Board while brainstorming on how to use the technology employed by fighter aircrafts to see through clouds and operate in pitch darkness.
