India is undertaking a significant rail infrastructure project to strengthen connectivity between the Northeast and the mainland by 2030. The initiative aims to reduce reliance on the narrow 22-kilometer Siliguri Corridor, known as the "Chicken’s Neck," a critical geopolitical chokepoint. New rail lines in Mizoram, Nagaland, Manipur, and Sikkim are progressing, while Meghalaya faces delays due to local opposition. This expansion also addresses growing security concerns linked to regional geopolitics and seeks to enhance military and civilian connectivity.
