Train communication between Sylhet and the rest of the country was restored after being suspended for more than three hours due to an engine failure on the Dhaka-bound Upaban Express. The incident occurred around 6 a.m. on Tuesday, March 31, 2026, between Bhanugach and Shamshernagar railway stations in Moulvibazar district. A replacement engine from Sylhet brought the train to Shamshernagar station, allowing normal operations to resume by 9:15 a.m.

According to Shamshernagar Assistant Station Master Sagar Singh, the alternative engine successfully moved the stranded train. Passenger M A Ahad reported that the train stopped suddenly, causing panic among travelers when sparks appeared from friction between the jammed wheels and the rail. However, no fire or injuries were reported. Hundreds of passengers experienced significant delays and discomfort during the disruption.

Kulaura Station Master Roman Ahmed confirmed that no major schedule disruptions occurred, as the 3010-series engine from Sylhet restored movement and normalized train schedules shortly afterward.
