Aizawl Becomes 4th Northeast Capital Linked to National Railway Network

Mizoram's capital Aizawl is now linked to the Indian railway network through the 51.38-km Bairabi–Sairang line. The ₹5,021 crore project features 48 tunnels and a 104m tall bridge, marking a new era for Northeast connectivity.

In a significant boost to infrastructure development in Northeast India, Mizoram’s capital Aizawl has been officially connected to the national railway network through the Bairabi–Sairang New Line. This development marks a major milestone in India’s efforts to enhance regional integration and transportation connectivity in one of the country’s most geographically challenging regions.

Aizawl Becomes Fourth NE Capital with Rail Connectivity

With this project, Mizoram becomes the fourth northeastern state to have its capital linked by railway. The other states already connected are:

Assam
Tripura
Arunachal Pradesh

Previously, the railway in Mizoram extended only 1.5 km into the state, terminating at Bairabi in Kolasib district, near the Assam border.

Project Highlights: Bairabi–Sairang New Railway Line

Distance and Cost

Total project length: 51.38 km
Revised sanctioned cost: ₹5,021.45 crore

This railway project is a vital link between Bairabi and Sairang, a satellite town just 20 km from Aizawl. A successful trial run by the Northeast Frontier Railway (NFR) on May 1, 2025, marked the beginning of operations and a historic day for Mizoram.

Current Progress and Timeline

According to the Ministry of Railways, the project has achieved:

94.52% physical progress
97.13% financial progress

Project Segmentation:

Bairabi–Hortoki (16.72 km) – Commissioned in July 2024
Hortoki–Kawnpui (9.71 km) – To be commissioned by June 2025
Kawnpui–Mualkhang (12.11 km) – June 2025 target
Mualkhang–Sairang (12.84 km) – Expected operational by June 2025

Engineering Marvel in Challenging Terrain

Constructing this railway in Mizoram’s hilly and forested terrain posed significant engineering challenges. The infrastructure built for the line includes:

48 tunnels with a total length of 12,853 meters
55 major bridges and 87 minor bridges
5 Road Over Bridges (ROBs)
6 Road Under Bridges (RUBs)

Bridge No. 196: Taller Than Qutub Minar

One of the most iconic structures of this project is Bridge No. 196, which stands at 104 meters tall — making it 32 meters taller than the Qutub Minar, one of India’s best-known monuments.

Strategic Importance and Broader Impact

This development is a part of India’s larger “Act East” policy and PM Gati Shakti National Master Plan, which aims to:

Integrate remote and border states with national infrastructure
Promote economic growth and regional equity
Improve access to education, healthcare, and markets in the NE region
Enable faster and more reliable movement of people and goods

The Aizawl-Sairang connection is expected to catalyze commercial, tourism, and logistic activity, giving a significant push to the local economy and reducing road dependency in a state known for its rugged terrain.
