Ministry of Railways, Railway Board has initiated a proposal to install TRI-NETRA systems 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.

This system shall 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 shall act as three eyes (Tri-Netra) of the Locomotive Pilot.  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 and to create a composite video image which shall be displayed in front of the Loco Pilot on a computer monitor.
