The intercity Bijoy Express train departed from the accident site near the inner signal of Gauripur rail junction in Mymensingh early Wednesday night, leaving behind three derailed coaches. The train resumed its journey toward Chattogram around 12:30 a.m. after the incident, which occurred at about 10:45 p.m. when the last three coaches went off the tracks. Several passengers were injured in the derailment.

According to Gauripur station master Shafiqul Islam, the train continued its journey with 11 coaches following instructions from higher authorities to minimize passenger inconvenience. Announcements were made at the station informing passengers from the damaged coaches to shift to other compartments. Passengers who wished to cancel their trips were offered ticket refunds, though none accepted. Rail officials stated that the derailment occurred because the line automatically changed after the signal time expired, diverting the last three coaches to another track.

Train movement between Gauripur and Chattogram remained suspended for about two hours following the accident before normal operations resumed.
