Key Recent Developments
In March 2024, India and Bhutan finalized plans to build two key rail links – the 69-km Kokrajhar–Gelephu line and the 16-km Banarhat–Samtse line, which will connect West Bengal to Bhutan. These projects will give Bhutan its first-ever railway connectivity.
The Northeast Frontier Railway (NFR) has already issued a Special Railway Project (SRP) notification under the Railways Act, 1989, and funds have been set aside for surveys and initial works.
Key Role in Regional Growth
The Special Railway Project (SRP) status is given to projects of national and strategic importance. The India Bhutan rail link holds this recognition because it will improve cross-border connectivity and strengthen national security.
Beyond security, the project is expected to drive socio-economic development in the region. It also plays a vital role in India’s Act East Policy, which focuses on building stronger partnerships with neighboring countries.
Project Overview and Investment
The Kokrajhar–Gelephu rail line is estimated to cost around ₹3,500 crore. The Northeast Frontier Railway (NFR) has already completed the detailed project report along with the final location survey. The corridor will include six new stations – Balajan, Garubhasa, Runikhata, Shantipur, Dadgiri, and Gelephu.
To support the route, the project will feature two major viaducts, 29 large bridges, 65 smaller bridges, one road overbridge, and 39 road underbridges.

Construction and Design Details
The Kokrajhar–Gelephu rail project faces challenging terrain, requiring advanced engineering solutions. Two viaducts, each 11 metres long, will allow trains to safely cross difficult landscapes.
The multiple bridges and road crossings are designed to ensure smooth travel and connectivity. This infrastructure not only improves transportation but also integrates remote areas, promoting local development and growth.
Economic and Social Advantages
The India Bhutan rail link is set to boost trade and tourism between the two countries, making it easier to move goods and people. Enhanced connectivity is expected to drive economic growth in both the Northeast region of India and Bhutan.
Beyond economics, the project will also strengthen diplomatic relations by improving physical and strategic ties between the nations.
