Railways in Jharia Coalfield

Jharia Coalfield has a series of railway lines covering the region lying between the Grand Chord line on the north and the Damodar river in the south. It consists of five lines of which four are managed by East Central Railway's Dhanbad railway division and one is managed by the South Eastern Railway's Adra railway division.

History
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.

The Bengal Nagpur Railway extended its then mainline, the Nagpur–Asansol line, to Netaji SC Bose Gomoh, on EIR’s Grand Chord, in 1907. The Mahuda Junction–Chandrapura branch line was opened in 1913.

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."

EIR had four major sections:
 * Kumardhubi–Gomoh section
 * Pradhankhanta–Pathardih section (15 km), opened in 1913
 * Dhanbad–Phularitand section (21.6 km), opened in 1894 to Katrasgarh and extended to Phularitand in 1924
 * Dhanbad–Pathardih section opened in 1903.

BNR had one section from Sudamdih to Gomoh.
