and New Delhi-Sealdah Rajdhani Express trains are delayed by 15 hours. The New Delhi-Howrah Rajdhani Express, scheduled to arrive in Dhanbad at 6:30 AM, arrived at 10:06 PM. The New Delhi-Sealdah Rajdhani Express arrived at 9:48 PM instead of 6:18 AM. Other trains like the Purva Express, Netaji Express, Doon Express, and Durgaiana Express also faced significant delays. The fog safety devices, designed to prevent accidents and ensure safe train operations, use GPS technology to provide train drivers with real-time information about track conditions, signals, and crossings, helping them maintain safe speeds even in foggy conditions.

Some passengers express dissatisfaction with the heavy expenditure on these devices while still facing delays. The devices work by providing the driver with information about the track, including potential obstacles, allowing them to adjust speed or stop as needed.
