Central Railway (CR) authorities on Sunday said they had introduced ‘talking signals’ to ensure the safety of train operations during foggy weather. Termed the Fog Safety Device (FSD) to assist locomotive pilots when the signal visibility is poor, this innovative technology acts as a crucial aid, significantly reducing the risks associated with low visibility conditions.

“With GPS functionality, the device provides notifications in advance to loco pilots regarding the next three upcoming signals using audio and visual indications. The device calls out and displays the description of the next signal and indicates the intermediate distance between the locomotive and the signal, ensuring better preparedness for changes,” an official said. According to the official, all signals and level crossing gates across various crew routes have been meticulously mapped through GPS locations and programmed into the device, ensuring comprehensive coverage.
