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, as many as 43 Delhi-bound trains have been delayed by up to five hours. These include the Padmavat Express, the Kalindi Express, the Shramshakti Express, the Mahabodhi Express, the Ashram Express, the Vikramshila Express, and the Kaifiyat Express. Passengers are advised to check the latest status of the trains before arriving at the station to board them.
