Sonnagar- Dankuni Section 

The Sonnagar–Dankuni section, originally part of the Eastern Dedicated Freight Corridor (EDFC), spans approximately 538 km and traverses three states: Bihar, Jharkhand, and West Bengal. It passes through two zonal railways: East Central Railway (ECR) and Eastern Railway (ER).

In 2022, the Sonnagar–Andal section was sanctioned as a multi-tracking project under the EPC mode and subsequently handed over to ECR and ER.

The Andal–Dankuni section, covering 163 km, lies entirely within the state of West Bengal and falls under the jurisdiction of Eastern Railway.

This section includes two junction stations (New Khana and New Dankuni), two crossing stations (New Rajbandh and New Jaugram), and one cabin at Andal East. As of now, approximately 97% of the required land for this section is under possession.
