India will build a 13 km (8. 1 mi) railway linking Tripura's capital Agartala with Bangladesh's southeastern city of Akhaura, an important railway junction connected to Chittagong port, resource-rich Sylhet and Dhaka. An agreement to implement the railway project was signed between India's former Prime Minister Manmohan Singh and Bangladesh Premier Sheikh Hasina during her visit to India in January 2010. Total cost of the proposed project is estimated at ₹252 crore (US$37 million). The Indian Railway Construction Company (IRCON) is constructing the new railway tracks on both sides of the border. Of the 13 km (8. 1 mi) rail line, 5 km (3. 1 mi) of tracks fall in Indian territory. The Northeast Frontier Railways (NFR) is laying the connecting tracks for the new rail link on the Indian side, up to Tripura's southern-most border town, Sabroom - 135 km (84 mi) south of Agartala. From Sabroom, the Chittagong international sea port is 72 km (45 mi) away.
