Train accidents in Bangladesh
Train accidents are common in Bangladesh, many at unmanned level crossings and some due to the poor condition of tracks.
According to data provided by the Bangladesh Railway, in August 2019, only 466 gates of its 1,412 level crossings had gatemen.
In November 2019, a deadly collision occurred between Dhaka-bound Turna Nishita Express and Chattogram-bound Udayan Express on the Dhaka-Chattogram route near the Mandbagh railway station in Kasba upazila of Brahmanbaria.
