In a significant step towards enhancing connectivity in the North-East, Mizoram’s capital Aizawl has been linked to the national railway network through the newly completed Bairabi–Sairang line. This development marks a major milestone in the region’s infrastructure progress.

Previously, Bairabi in Kolasib district—located near the Assam border—served as the only railway station in Mizoram. The new line extends the network to Sairang, a satellite town situated about 20 km from Aizawl.

A senior official from the Ministry of Railways stated that the formal inauguration of the Bairabi–Sairang railway line is expected to take place after June 17. The Commission of Railway Safety (CRS) is scheduled to inspect the project this week, and the inauguration and commencement of operations will follow only upon successful completion of this inspection. The official added that the majority of construction work is complete, with only a few minor works pending.

The CRS inspection represents the final phase before train services can begin. A successful trial run was carried out by the Northeast Frontier Railway (NFR) on May 1, symbolising a historic achievement for the state.

With this development, Mizoram becomes the fourth state in the North-East to have its capital connected to the national railway network, joining Assam, Tripura, and Arunachal Pradesh.

Until now, railway access in Mizoram extended just 1.5 km beyond the state border. The Bairabi–Sairang New Line spans 51.38 km and has a revised sanctioned cost of Rs 50.21 billion.

According to data from the Ministry of Railways, the project has achieved 94.52 per cent physical progress and 97.13 per cent financial progress. It is divided into four sections: Bairabi–Hortoki (16.72 km), which was commissioned in July 2024; and the remaining sections—Hortoki–Kawnpui (9.71 km), Kawnpui–Mualkhang (12.11 km), and Mualkhang–Sairang (12.84 km)—are expected to be operational by June.

The project posed significant engineering challenges due to Mizoram’s difficult terrain. The line includes 48 tunnels stretching a combined 12,853 metres, 55 major bridges, 87 minor bridges, five Road Over Bridges (ROBs), and six Road Under Bridges (RUBs). Among its most remarkable structures is Bridge No. 196, which stands 104 metres tall—32 metres higher than the Qutub Minar.

The Bairabi–Sairang project forms part of the Ministry of Railways' broader strategy to connect all North-Eastern state capitals by rail and improve regional infrastructure. This includes a series of new line and doubling projects across Assam, Nagaland, Arunachal Pradesh, Sikkim, Manipur, and Tripura. However, progress in Meghalaya remains slow due to prolonged resistance from local pressure groups opposing rail connectivity in the state.
