Aizawl, the capital of Mizoram has now become the fourth Northeast state capital to join the national railway network, along with Dispur (from Assam) and the two from Arunachal Pradesh- Itanagar and Naharlagun. The Bairabi-Sairang rail project which took Rs 5,021 crore to build over 51.38 km, links Aizawl to Sairang, a neighboring town 20 km from the state capital. The government is making infrastructure in Northeastern India a priority and connectivity is a key part of this push. A number of other capitals such as Gangtok, Imphal, Kohima and Shillong, are yet to get railways.
