In the face of mounting frustrations among air travelers due to frequent flight delays and cancellations, particularly in North India, passengers opting for train travel are experiencing comparatively smoother journeys thanks to an innovative GPS-enabled device known as the 'Fog Pass.' Introduced by the Indian Railways, this technological solution aims to alleviate delays and disruptions caused by dense fog during the winter months, a perennial challenge affecting numerous trains, especially in northern regions.
With the installation of 19,742 'Fog Pass' devices, primarily in trains operating in the northern division, the Indian Railways seeks to enhance navigation capabilities for loco pilots in foggy conditions. The 'Fog Pass' serves as a navigation device, providing real-time information, both visually and through voice guidance, to loco pilots regarding crucial landmarks such as signals, level crossing gates (manned and unmanned), permanent speed restrictions, and neutral sections.
The device displays the next three approaching landmarks in geographical order and issues a voice message approximately 500 meters before the approach. Its special features include compatibility with various types of rail sections, electric and diesel locomotives, and speeds up to 160 mph. The device is equipped with a built-in rechargeable battery backup lasting for 18 hours, making it suitable for all weather conditions.
One of the notable advantages highlighted by Ravinder Singh, Chief Local Inspector of the Northern Division, is the device's accuracy in displaying distances from landmarks even under near-zero visibility. The 'Fog Pass' ensures seamless communication by providing voice commands about incoming signals and distance in meters during periods of low visibility.
Singh further explained the functionality of the device, emphasizing its simplicity and efficiency. The loco pilot is equipped with the 'Fog Pass' before commencing the journey, and the device, complete with an antenna, operates in two modes – automatic and manual. In automatic mode, it captures signals and displays the train's route, while manual mode allows for efficient operation even if the automatic mode fails. The device can display up to three signals upfront and indicates distances up to nearly 999 meters ahead, enhancing safety and navigation for trains navigating through challenging foggy conditions.
