The '''Bengal and Assam Railway''' (BARB&AR) was formed on 1 January 1942 by the amlgamation of the [[Assam-Bengal Railway]] (ABR) with the [[Eastern Bengal Railway]] (EBR).

On the expiry of the [[Assam Bengal Railway|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'''. In a similar mannerOn 1 April 1942, on the BAR took over operational control of the [[Dibru-Sadiya Railway]] for the duration of the war (WW2). On 1 October 19441943, the GoI took over the [[Jorhat (Provincial) State Railway]] and on 1 October 1944, the [[Sara-Sirajgonj Railway]] and merged it , merging both in turn into the BARB&AR.

In 1947For administrative convenience, the BAR section of the B&AR west of the [[Brahmaputra]] was split up and those parts ramaining within referred to as the area of East Pakistan were renamed '''Eastern Bengal Railway'EB Zone'' with ownership and control vesting in that to the Central Government of Pakistan. In 1961, east as the system was further renamed '''Pakistan Eastern Railway'AB Zone'', retaining the nomenclature in use before the amalgamation.

In 19721947, 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 became '''Bangladesh Railway''']].
