NEW DELHI: Railways may soon get an advanced system, called "Tri-Netra", on its trains which will help reduce train accidents by keeping a record of the track maintenance and will also provide better visibility during foggy days. Senior railway officers said Tri-Netra system is made up of a high-resolution optical video camera, high-sensitivity infrared video camera and a radar-based terrain mapping system.Tri-Netra stands for ­ "terrain imaging for diesel drivers infrared, enhanced optical and radar assisted system". The system provides a locomotive pilot a clear view of up to one kilometre on a straight track, even during inclement weather. This helps in maintaining high speed in poor visibility and avoid delay in arrivals.The new technology has been used on a trial basis and has shown good results. Senior officers said that once it is proved to be reliable, it may be brought to use this winters. The requirement for the system gained more pace after 14 bogies of the Patna-bound Indore-Rajendra Nagar Express went off the tracks near Kanpur Dehat in the early hours of Sunday.
