The 40km Shield: India’s Underground Rail Masterplan

The Central government has announced plans to construct underground railway tracks along a 40-km corridor in West Bengal to enhance connectivity between the North East and the rest of India.

Union Minister for Railways Ashwini Vaishnaw said the proposed underground section will span the stretch between Tin Mile Haat and Rangapani stations. The project is considered strategically significant, as the region—often referred to as the “chicken’s neck”—is critical for both transportation and national security.

In addition to the underground alignment, the plan includes upgrading the existing railway network to a four-line system, which will substantially increase capacity, efficiency, and reliability. The underground segment, owing to its strategic importance, is expected to enhance the resilience of the transport network against potential security threats.

The initiative forms part of the government’s broader efforts to strengthen regional connectivity, improve safety, and reinforce vital infrastructure links with the North East.
