The Howrah–
Amta light railway had its origin in an agreement, dated 12 June 1889 between the District Board of Howrah and Messrs. Walsh, Lovett & Co., which was subsequently renewed with Messrs.
Martin & Co., and sanctioned by Government notification in the Calcutta Gazette of 27 March 1895. This was one of the Martin lines which was on 2'0" gauge instead of the more common 2'6". The railway connecting
Howrah and
Amta in
West Bengal was opened up to
Domjur in 1897, and to Amta in 1900. An extension from Bargachhia (Bargachha) Junction to
Antpur was opened in 1903, and a further extension to
Champadanga in 1905. The total length of the railway was . Both the Howrah- Amta and Howrah-Seakhala lines used to start from Howrah NG (Telkal Ghat) Station (near Howrah Rail Museum) on the Hooghly river, running to Dasnagar station. Here they separate, the Howrah-Seakhala & Janai line running North-West along the Benaras Road to Seakhala & Janai in Hooghly district. The Howrah–Amta line runs west, chiefly along the side of the Jagatballavpur Road, and then goes south-west to Amta, with a long branch line to
Champadanga from Bargachhia (Bargachha) Junction. The railway was converted to
Broad Gauge in phase starting from 1984 and completing in 2000 with a slightly different alignment. Only the Howrah–Amta long section was rebuilt, while the long branch line from Bargachhia Junction to
Champadanga with extension to
Tarakeswar is under planning since 2001. Work in long line from Bargachhia (Bargachha) Junction to
Tarakeswar via
Antpur &
Champadanga is delayed. There was some construction of a new alignment from Howrah station which utilized the existing route up to Santragachhi Junction and skipped some of the older stations up to Makardaha, while new stations came up on this alignment at Bankra Nayabaz, Baltikuri Junction, Kona, Dansi and Jhaluarber. While some stations from the old line have been retained, some stations on the rebuilt line are at new locations. But the new BG alignment measures the exact as the old NG alignment. This route is now part of
Kolkata Suburban Railway. It has been electrified and EMU local trains run between Howrah and Amta. This route now comes under the jurisdiction of the South Eastern Railway. == Howrah–Seakhala light railway ==
