Radhikapur-Biral and Singhabad-Rohanpur are also notified for use of Nepalese transit traffic.
"Kolkata is a major destination for people in this area, but as of now there was no direct connectivity to the city. The line will help not only people from Agartala but also those from Mizoram which is 150 km away," Chief engineer of the Rs 570 crore project M S Chauhan said.
The line will be operational by 2020, he said.
The trains on the line will undergo security check once at Nishchintpur on the Indian side and Gangasagar on the Bangladesh side, sources said.
This line will be instrumental in freight movement as well as goods from the northeastern state can now reach Kolkata in one third the time. Similarly, goods from Chittagong port will reach Agartala quicker.
