Train operations in northern Bangladesh resumed after a 21-hour suspension following the derailment of the Nilshagar Express near Santahar in Bogura. The incident occurred around 2 p.m. on Wednesday, March 18, about two kilometers north of Santahar station. Services were restored at 11:20 a.m. on Thursday, March 19, when the Khulna-bound Simanta Express departed from Chilahati using a newly repaired track.

Authorities reported that at least one hundred people were injured in the derailment, many of them passengers who jumped from the train roof in panic. Fire service teams, assisted by local residents, carried out rescue operations, sending 50 to 60 injured passengers to Naogaon General Hospital and Adamdighi Upazila Health Complex. Four fire service units and a relief train from Ishwardi Junction participated in the recovery of nine derailed coaches.

Following the incident, the assistant station master at Santahar was temporarily suspended, and a four-member investigation committee was formed to determine the cause of the accident.
