The movement of several trains is affected as dense fog has engulfed the Delhi-NCR region, causing low visibility. According to Indian Railways, as many as 25 Delhi-bound trains have been delayed by up to four to five hours. These include the Farakka Express, Prayagraj Express, Malwa Express, Pooja Express, Tamil Nadu Superfast Express, Padmavat Express, Ashram Express, Purushottam Express, and Karnataka Express. Passengers are advised to check the latest status of the trains before arriving at the station to board them.
