A Chattogram-bound train named Udayan Express, which departed from Sylhet, left three of its coaches behind near Hasanpur station in Nangalkot upazila of Comilla on Wednesday morning. The incident occurred around 6 a.m. when the coaches became detached, causing severe inconvenience to passengers. The separated section included the guard brake coach, which houses the train director, a canteen, and 15 passenger seats. Thousands of passengers narrowly escaped a major accident.

Following the detachment, the train was delayed in reaching Chattogram. Railway staff worked for nearly two hours to reconnect the separated coaches to the main engine. Once reattached, the train resumed its journey toward Chattogram from the Hasanpur area. According to Hasanpur station master Nasir Uddin, the train split between Hasanpur and Gunabati, outside the station area, and normal train movement resumed about 20 minutes after the incident.

Train operations on the down line later returned to normal, and no further disruptions were reported in the area.
