The line directly connects the Sealdah railway station (erstwhile Calcutta railway station) on the east bank of the Hooghly River with the Howrah–Bardhaman chord line at the Dankuni Junction on the west bank of the Hooghly River via the Vivekananda Setu. There is also a 9 km (5.6 mi) long branch line (known as the A.C.C. link line) from Dankuni Junction which connects this line with the Santragachi–Amta branch line and Andul on the Howrah–Kharagpur line.
The Howrah-Bardhaman Chord, a shorter link to Bardhaman from Howrah than the Howrah-Bardhaman Main Line, was constructed in 1917. In 1932, the Calcutta Chord Line was built over the Willingdon Bridge (Vivekananda Setu) joining Dum Dum with Dankuni.
The ACCL line was primarily used by freight trains to bypass the congested sections near Howrah and directly connected the Eastern railway and South Eastern railway zones. However with increasing public demand, some long distance passenger trains were started in this section directly via Sealdah like the Sealdah–Puri Duronto Express in 2012.
The Dum Dum-Dankuni section was electrified in 1964-65. The Andul-Dankuni section was electrified in 1971-72.
