Mizoram’s long-pending plan to extend railway connectivity from Sairang, near Aizawl, to Hmawngbuchhuah on the India–Myanmar border has received renewed attention after Chief Minister Lalduhoma met with senior railway officials on October 27.
According to the Mizoram government’s Directorate of Information and Public Relations (DIPR), railway officials informed the Chief Minister that the proposed line would stretch 230.110 km and have 20 stations. Trains on the corridor are proposed to operate at speeds of up to 130 kmph.
The latest proposal follows years of surveys, revisions and discussions over the strategic importance and financial viability of extending railway connectivity into southern Mizoram.
What is the proposed railway corridor?
The proposed Sairang–Hmawngbuchhuah railway line would extend the existing railway network beyond Sairang, near Aizawl, towards the southernmost part of Mizoram.
Hmawngbuchhuah is a village in Lawngtlai district, located along the India–Myanmar border.
The area is strategically significant because nearby Zochachhuah is connected to the Kaladan Multi-Modal Transit Transport Project (KMMTTP), an India–Myanmar connectivity initiative linking Mizoram with Myanmar’s Rakhine State and the Bay of Bengal.
According to an August 2023 announcement by the Mizoram Governor’s office, which reproduced a press release from Northeast Frontier Railway, the proposed 223-km broad-gauge line would connect Sairang with Hmawngbuchhuah, near the Myanmar border.
The project is intended to improve regional connectivity and could provide another route for transporting goods between Northeast India and Myanmar’s Sittwe Port.
Which districts could the railway line pass through?
The route would traverse six Mizoram districts: Aizawl, Serchhip, Hnahthial, Lunglei, Siaha and Lawngtlai. The precise alignment and the districts the final railway line will pass through should therefore be confirmed against the railway authorities’ final-location survey or detailed project report.
Why is Hmawngbuchhuah important?
Hmawngbuchhuah’s importance extends beyond its location at the southern end of Mizoram. Its proximity to the India–Myanmar border and the Kaladan Multi-Modal Transit Transport Project makes it a potential strategic point for cross-border trade and regional connectivity.
The KMMTTP is designed to connect India’s eastern seaboard with Northeast India through Myanmar. Its infrastructure includes a maritime route through Sittwe Port, inland water transport along the Kaladan River to Paletwa, and a road connection towards Mizoram.
Nearby, Zochachhuah is an important point along the road component of this project, where the route enters Myanmar.
In October 2025, Chief Minister Lalduhoma had mentioned in a meeting that the Centre was taking steps to extend railway connectivity to Hmawngbuchhuah. He linked the proposed railway extension with the broader prospects for development in southern Mizoram.
A proposal dating back more than a decade
The idea of extending railway connectivity from Sairang to Hmawngbuchhuah has been under discussion for years.
In August 2015, Indian Railways completed a preliminary survey for a possible extension from Sairang to Hmawngbuchhuah. The proposed route was intended to reach Mizoram’s southern tip near the Myanmar border and the road corridor associated with the Kaladan project.
At the time, the proposal was viewed as a potential way to strengthen transport links between Mizoram, Myanmar and the wider region.
The existing railway infrastructure in Mizoram had developed in stages. The 84-km Katakhal–Bairabi section, connecting Assam with Bairabi in Mizoram, underwent gauge conversion and was commissioned in May 2016. The subsequent 51.38-km Bairabi–Sairang new railway line was completed and commissioned in September 2025.
Why was the project stalled?
Despite its strategic potential, the proposed railway line faced financial concerns.
In a written reply to the Lok Sabha on March 16, 2022, then Railway Minister Ashwini Vaishnaw stated that a reconnaissance engineering-cum-traffic survey had been conducted for a proposed 223-km broad-gauge line from Sairang to Hmawngbuchhuah.
According to the survey report, the project was estimated to cost ₹15,007 crore and had a rate of return of minus 10.45 per cent. The government said the project could not be taken forward because it was financially unviable.
The negative rate of return indicated that the project was not expected to generate sufficient financial returns relative to its estimated cost under the assessment.
The project returns to the agenda
In September 2022, Mizoram MP C. Lalrosanga urged railway authorities to pursue the proposed extension, highlighting its potential significance for the Act East Policy and the Kaladan project.
In August 2023, the Mizoram Governor’s office announced that the Railway Board had approved a Final Location Survey for the proposed 223-km line from Sairang to Hbichhuah near the Myanmar border. The announcement, which reproduced a Northeast Frontier Railway press release, said the project could support trade connectivity and economic development in the Northeast.
A January 2024 report by Zalen subsequently stated that the Ministry of Railways had sanctioned ₹33.15 crore for the survey work. Citing railway consultant R. Hrangtawna, the report said the funding would be used to identify the actual railway alignment and proposed station locations.
The reported sanction was for survey-related work, not for the construction of the entire railway line.
In December 2025, a Lok Sabha answer on railway development in the Northeast stated that a Final Location Survey for the 223-km Sairang–Hbichhuah new line had been sanctioned for preparation of a Detailed Project Report (DPR). The Railway Ministry reiterated the survey status in a Rajya Sabha reply in March 2026.
