Introduction & Background:

  • The Eastern Corridor spans from Ludhivana to Dankuini. The Eastern Corridor has a route length of 1875 km. On the Eastern Corridor, DDU — Khurja — Ludhiana section is funded through World Bank loan and equity from MoR, whereas Sonnagar —DDU is funded by equity from MoR.
  • The proposed alignment of Sonnagar (New Chiraila Pauthu)-New Andal section is a part of Eastern Dedicated Freight Corridor and passes through Aurangabad and Gaya District of Bihar, Koderma, Hazaribagh, Giridih and Dhanbad district of Jharkhand and Paschim Bardhaman district of West Bengal.
  • Pursuant to requisite Cabinet approval, DFCCIL has decided to implement the project Sonnanagr to Andal (a section of approx.375 RKM) through Engineering, Procurement, Construction (”EPC”) mode. The Project shall be funded through equity provided by Indian Railway.
  • Sonnagar (New Chiraila Pauthu)-New Andal stretch of DFC starts from New Chiraila Pauthu station of EDFC and passes through New Koderma Junction, New Gomoh, New Pradhankanta of East Central Railway and meets at New Andal Junction on the Eastern Railway. The route length of this section is approx. 375 Fans. Total 10 Stations including 6 Junction Stations and 4 Crossing stations have been planned. In addition to this, one cabin at New Katipahari is also planned in this section.
  • The project shall be undertaken under the jurisdiction of CGM/Kolkata.
  • PETS survey has been carried out. Detailed project report (DPR) for the Sonnagar-Andal Section (374.534 Km) Jan 2023 has been prepared and accepted by the competent Authority.

Scope of Work:


  • Most of the proposed alignment of Sonnagar (New Chiraila Pauthu)-New Andal section is parallel to existing Indian Railways lines wherever feasible to utilize available Railway lands to the extent possible.
  • Wherever alignment parallel to IR is not possible, detours are proposed. Two detours are planned in the proposed section, the first detour is taken in Gaya to avoid heavily built- up and densely populated Gaya town.
  • Another detour is planned after Paharpur station. Paharpur- Koderma- Gurpa section traverses the hilly and forest terrain of Chota Nagpur Plateau range and having gradient of 1 in 100. To maintain the DFC’s standard ruling gradient of 1 in 200, a second detour is planned.



Package-1- Integrated Contract Package of Civil, Building and Track Works, Electrical and Signalling & Telecommunication Works from Sonnagar- Koderma (including Koderma detour)



169.49 RKM (including Koderma detour of length 63 KM)


Package-2- Integrated Contract Package of Civil, Building and Track Works, Electrical and Signalling & Telecommunication Works from Koderma (excluding Koderma detour) — Andal
