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. File:Raniganj Coalfield 1867.jpg 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. 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==
