It was possible to develop mining in the Jharia Coalfield in the late nineteenth century primarily because of the introduction of railways. East Indian Railway Company extended the Grand Chord to Katrasgarh via Dhanbad in 1894.[3]
The District Gazetteer of Manbhum noted that: "There is a network of railway line in this district passing through colliery area. Grand Chord Line of the Eastern Railway and branch line of South Eastern Railway pass through this district from Gomoh Junction two railway line one of the Eastern Railway and another of the south Eastern Railway branch off, one going to Dehri on Sone (Shahabad) via Barkakana and another from Gomoh to Adra (Purulia district). There are branch lines in both the railway for carrying coal to different places in the country."[5]

Electrification of the stretch of mainline of this section from Asansol to Netaji SC Bose Gomoh was completed in 1960–61.[6]
