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'''. 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 BARB&AR.
