Summary

Prime Minister Narendra Modi inaugurated the Bairabi–Sairang new rail line, worth over ₹8,070 crore, on 13 September 2025, connecting Mizoram's capital to the Indian Railways network for the first time. Bad weather kept him at Lengpui Airport, so he addressed the Aizawl event by video-conference as part of projects worth over ₹9,000 crore. The 51-km line, built through difficult hilly terrain, has 45 tunnels, 55 major bridges and 88 minor bridges. The PM flagged off three new trains: the Sairang (Aizawl)–Delhi (Anand Vihar) Rajdhani Express, the Sairang–Guwahati Express and the Sairang–Kolkata Express. He also laid the foundation stone of road projects, including the 45-km Aizawl Bypass under PM-DevINE.
