This line was meant primarily for the collection of jute and its onward dispatch to Kolkata, then known as Calcutta.

[2][3][4][5] The line was extended for another 88 kilometres (55 mi) to Jagannathganj Ghat, on the east bank of the Jamuna, soon after its opening.

The Bahadurabad Ghat–Jamalpur (also known as Singjhani) metre gauge line was opened in 1912, connecting it to another point on the Jamuna.

[3][4] The construction of this track opened up the possibilities of linking such places as Gouripur, Kishoreganj, Bhairab Bazar and Mohanganj through branch lines.

[8] The construction of the 4.8 kilometres (3.0 mi) Bangabandhu Bridge has completely changed the scope of communication systems in this part of the country.

[3] On 24 April 2013, the first Diesel Electrical Multiple Unit (DEMU) service in the country was inaugurated between Narayanganj and Dhaka.

Twenty DEMU sets were purchased from Chinese manufacturer CRRC Tangshan for Tk 460 crore (US$59 million as of 2013).

[12][13][14] Eighteen months later, the Dhaka Tribune characterized the DEMU service as "a lemon" because travel time was little better than conventional service, carriages had inadequate ventilation, and there was a three-foot mismatch between carriage door and station platform heights.
