|How to interpret this infobox|
On the expiry of the Assam-Bengal Railway's contract at the end of 1941, the Government of India exercised its option and took over the ABR, merging it with the EBR to create the Bengal and Assam Railway. On 1 April 1942, the BAR took over operational control of the Dibru-Sadiya Railway for the duration of the war (WW2). On 1 October 1943, the GoI took over the Jorhat (Provincial) State Railway and on 1 October 1944, the Sara-Sirajgonj Railway, merging both in turn into the B&AR.
For administrative convenience, the section of the B&AR west of the Brahmaputra was referred to as the EB Zone and that to the east as the AB Zone, retaining the nomenclature in use before the amalgamation.
In 1947, the B&AR was divided between the two new nations of India and Pakistan. That part remaining in India was renamed the Assam Railway; in 1952, this was merged into a new zone of Indian Railways, North Eastern Railway.
The part of B&AR within the area of East Pakistan was renamed the Eastern Bengal Railway with ownership and control vested in the Central Government of Pakistan. In 1961, the system was further renamed Pakistan Eastern Railway.
In 1972, Pakistan Eastern Railway became Bangladesh Railway.
