The movement of several trains has been affected as dense fog has engulfed the northern region of the country, causing low visibility. According to Indian Railways, nearly 30 Delhi-bound trains have been delayed by up to three hours. These include the Shram Shakti Express, Poorva Express, Padmavat Express, Ayodhya Express, Lucknow Mail, Shramjeevi Express, Vikramshila Express, and Malwa Express. Passengers have been advised to check the latest status of the trains before arriving at the station to board their trains.
