Fog No More: Indian Railways’ High-Tech Devices Ensure On-Time Winter Journeys


Our humble insight into Indian Railways cutting-edge technology for uninterrupted journeys during harsh winter conditions


Winter’s icy grip often brings with it a dense blanket of fog, wreaking havoc on travel schedules and causing frustration for passengers. Yet, Indian Railways is taking decisive action to ensure smooth operations even in the face of reduced visibility. Their weapon of choice? A fleet of 19,742 high-tech “Fog Pass Devices” deployed across the network.

These innovative devices, akin to GPS navigators for trains, empower loco pilots with crucial information even when shrouded in fog. Picture this: as the locomotive hurtles forward, the Fog Pass Device displays the locations of essential landmarks like signals, level crossings, and speed restrictions on a dedicated screen. Not only that, it provides clear voice guidance, alerting the pilot about upcoming obstacles 500 metres ahead. This real-time assistance ensures trains stay on track, literally and figuratively, minimizing delays and maximizing passenger safety.

This initiative marks a significant leap forward for Indian Railways. No longer will winter fog throw a wrench into travel plans. With the Fog Pass Device as their trusty co-pilot, loco pilots can navigate even the densest fog with confidence, ensuring a seamless and stress-free journey for passengers across the nation. So, the next time you embark on a winter train journey, rest assured that cutting-edge technology is working tirelessly behind the scenes to get you to your destination safely and on time.
