Assam tea
In response to the demands of the Assam tea planters for a railway link to Chittagong port, Assam Bengal Railway started construction of a railway track on the eastern side of Bengal in 1891. A track between Chittagong and Comilla was opened to traffic in 1895. The Comilla–Akhaura–Kulaura–Badarpur section was opened in 1896–98 and extended to Lumding by 1903.
