[4][5] While the main line of the eastern section of the Eastern Bengal Railway (reporting mark :EBR) was opened from Calcutta to Kushtia via Ranaghat in 1862, it bypassed Krishnanagar and Shantipur, two very prominent heritage centers of art, culture and learning of the 18th and 19th century Bengal.

[6][7] To resolve this issue, Martin's Light Railways (reporting mark :MLR) constructed a 20.25 mi (32.59 km) long, 2 ft 6 in narrow gauge line from Aistala Ghat, on the west bank of the Churni river, near Ranaghat to Krishnanagar via Shantipur in 1899 which was known as the Ranaghat–Krishnanagar Light Railway.

[16] This bridge was destroyed in the Second World War, leading to connectivity problems between the twin cities of Azimganj and Jiaganj located on the opposite sides of the Bhagirathi river.

[17] Following the partition of India in 1947, the link between Sealdah and Katihar via this line was snapped[13] affecting the connection of South Bengal with North Bengal, North Bihar and Assam due to which the ferry connection was moved to between Sakrigali Ghat railway station in the Sahibganj Loop to Manihari Ghat railway station in the Katihar–Teznarayanpur branch line.

[23][24][25] The Krishnanagar–Nabadwip Ghat section was sanctioned for gauge conversion in 2007 along with a planned extension of the line to Nabadwip Dham on the B.B.

[26][27] On 15 October 2023, a trial run of a goods train was conducted between the Krishnanagar City Junction and Amghata railway stations in order to check the heath of the unutilized section of the new gauge converted line.

It is planned to short terminate trains at Amghata till the land acquisition problems between the Amghata–Nabadwip Ghat section are sorted out.

[28][29][30] A new railway bridge between Azimganj and Murshidabad, across the Bhagirathi river was sanctioned in 2001 owing to the long time demand of the people of the area.

[31][32][17][33] The hurdles related to land acquisition & employment were finally cleared & work for laying the tracks was started in December 2022.

[4] The Ranaghat EMU Carshed also maintains 12-car MEMU rakes which started serving from Sealdah to Lalgola in 2012.

[4] While the section was initially served by the Narkeldanga EMU carshed which opened on 1963, due to the increasing traffic requirements in the Ranaghat–Gede, Ranaghat–Bangaon, Ranaghat–Shantipur–Krishnanagar City and Ranaghat–Lalgola sections owing to the electrification and gauge conversions of various lines, the Ranaghat EMU carshed was commissioned in 2007.

[4] There have been multiple demands for a new railway line from Krishnanagar to Berhampore via Karimpur and Domkal, two major towns in the Nadia and Murshidabad districts of West Bengal.
