In 1881, railway first came to Assam when Assam Railway and Trading Company set up metre gauge track. The 65-km-long metre gauge line from Dibrugarh to Margherita was constructed mainly for transportation of tea and coal. This company later started the first passenger train in Assam by the name of Dibru–Sadiya Railway. The North Eastern Railway was formed on 14 April 1952 by amalgamating two railway systems: the Assam Railway and Oudh and Tirhut Railway. Later, it was bifurcated into two railway zones on 15 January 1958, the North Eastern Railway and the Northeast Frontier Railway.[1] to better serve the needs of the northeastern states.
