Assam tea
In response to the demand 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 1896–1898 and finally extended to Lumding in 1903. On 1 January 1906, Bengal Railway Company was merged with Assam Bengal Railway.
