Dibrugarh Railway Yard, 1943

The Assam Railway and Trading Company Limited was incorporated in 1881. The first metre gauge locomotive was put into service in Assam in 1882. The 64-kilometre (40 mi) long line from Dibrugarh steamer ghat to Makum was opened to passenger traffic on 16 July 1883. The objective of opening an isolated railway in upper Assam was to link the tea gardens and coalfields to the steamer ghats.

In the latter part of the 19th century, the Dibru-Sadiya railway was 126-kilometre (78 mi) long.[1] The 1,000 mm (3 ft 3 38 in) wide metre gauge railway track earlier laid by Assam Bengal Railway from Chittagong to Lumding was extended to Tinsukia on the Dibru-Sadiya line in 1903.[1][2] The Mariani-Furkating line was operated by Jorhat-Provincial Railway.[2]

The project for the conversion of the entire Lumding–Dibrugarh section from metre gauge to 1,676 mm (5 ft 6 in) wide broad gauge was completed by the end of 1997.[3]

The Guwahati-Lumding-Dibrugarh line was proposed to be doubled in the Railway Budget for 2016-17.[4] The 123-kilometre (76 mi) long Dimapur-Zubza-Kohima new line project has the status of a National Project. Final location survey has been completed for the entire project.[5][6] As of 2012, surveys are underway for 6 km (4 mi) long line from Tirap to Lekhapani and 31 km (19 mi) long line from Lekhapani to Kharsang in Arunachal Pradesh. Survey for 344 km (214 mi) long new line from Jorhat to Shibsagar was completed in 2010-11. Survey was completed for doubling of 520 km (323 mi) long line from Digaru to Dibrugarh. Survey is in progress for 190 km (118 mi) long new line from Dimapur to Tizit. Survey was completed for 31 km (19 mi) long new line from Amguri to Naginamora. The survey for 9 km (6 mi) long new line from Tuli to Tuli Town has been shelved.[7]
