Project Summary:
The 50.38-km broad gauge line from Bairabi in Kolasib district to Sairang, 20 km from Aizawl, is part of the railway's project to connect the capitals of the northeastern states. Hilly terrain, covered with dense forest, the railway route here has to traverse through a number of deep gorges and over several rivers flowing at low ground levels. While the high mountains are penetrated by constructing tunnels, the deep river gorges between the mountain ridges are connected by tall bridges.
