 After getting promising results of the trials of TRI-NETRA system, the railways plans to install the device in loco engines to ensure timely operations of trains during foggy weather.

TRI-NETRA is a system comprising of three image technologies to assist the driver to run the train even during dense fog or inclement weather. The system has a high resolution optical video camera, high sensitivity infra-red video camera and radar based terrain mapping system. The device would be fitted outside the loco engines and it uses GPS technology.
The three camera-based device beams clear video image of the track through a screen fitted inside the loco engine. The system shows that the track ahead is obstruction-free and maps the terrain ahead so that driver knows when the train is approaching a station or a signal.
 Sources said the two trials of the device, which were conducted on Lucknow-Delhi and Bangalore-Mysore routes, have been successful, prompting the department concerned to seek a final nod from the railway board to start installing the devices. 
According to the plan, as many as 3,000 electric and diesel loco engines would be fitted with TRI-NETRA device to ensure no train gets delayed or cancelled during foggy weather, which is quite common during the winter months in the northern parts of the country. Hundreds of trains run behind the schedule or are cancelled during winters.
An official said that around Rs 1 crore would be required to install the device in a loco engine.
Additional director general (PR), railway board, Anil Saxena told Governance Now that the technology is likely to be implemented from next year. “There will be a budgetary provision for this device,” Saxena said.
