Mining-industry zone
"The entire belt between Durgapur (158 km from Howrah), and all the way up to Dhanbad and beyond is industrialized. Apart from factories, there are many coalmines, some closed now, and some with fires burning deep in the mineshafts. Mining area extends for a large area, mostly to the south of the tracks. Quite a portion of the track passes through cuttings, where the surrounding area is higher than the track level, resulting in the profusion of characteristic small masonry bridges crossing the tracks." This description is from "Gomoh loco shed and CLW trip record" by Samit Roychoudhury. History
During the middle of the nineteenth century, Carr, Tagore and Company transported coal from Narayankuri ghat on the Damodar River to Kolkata, then known as Calcutta. However, as the flow of water in the river was inconsistent, supplies were irregular. In order to capture the lucrative coal transport business, East Indian Railway, extended the railway track that had been laid between Kolkata and  to  in 1855 and up to Asansol in July 1863. The East Indian Railway needed land to develop the infrastructure for the railways. While the Searsol Raj, then the zamindar in the Raniganj area, refused to provide the land, the Panchakot Raj, then functioning from Kashipur, agreed to provide the land in Shergarh, of which Asansol was then a part in 1863–64, East Indian Railway purchased a large area of jungle land from the Panchakot Raj, thereby initiating the development of Asansol as an industrial area. Subsequently, Asansol gained further in importance. What was later known as the Sahibganj loop was the first line from Kolkata to Delhi and the first direct train started in 1866, but the shorter line via Asansol and Jhajha came up in 1871. It was initially called the Chord line but as it attracted more traffic, was rechristened the main line and the earlier main line became Sahibganj loop. With the completion of the –Gaya–Mughalsarai Grand Chord in 1901 (formally inaugurated in 1906 and finally opened in 1907), the Kolkata–Delhi rail distance became even shorter, and Asansol started functioning as the junction station of the main and chord lines, as Sitarampur, the actual junction, near Asansol, is a comparatively smaller station. While momentous developments were taking place in connecting Delhi and Kolkata by rail, Bengal Nagpur Railway extended its tracks to the Asansol coal belt in 1887, thus connecting Adra with Asansol. The railway establishment at Asansol contributed substantially to its development and growth. Electrification
Electrification of the railways gained momentum in the early fifties. Although initial installations were with 3 kV DC traction, the railways subsequently adopted the 25 kV AC system. Electrification of the Bardhaman–Mughalsarai section was completed in 1957 and the Howrah–Gaya stretch was electrified by around 1960. The Tatanagar–Adra–Asansol section was electrified in the 1957–1962 period. Locomotive shed
Asansol Electric Loco Shed is home to the oldest electric locomotive shed of Indian Railways. It houses WAP-4, WAG-5, WAM-4 and WAG-7. Asansol Division
