Chronology of railways in India,(1947 – 1970)

• 1947

Apr. 1: Mandra-Bhaun line taken over by state (now in Pakistan).
Independence/Partition. Two big systems, Bengal Assam Railway and North Western Railway are no longer in India (these included the workshops of Saidpur and Mogulpura, respectively). Some 2955 route-km of NWR became the East Punjab Railway in India, leaving 8070km in the then West Pakistan. Part of the Jodhpur Railway also went to West Pakistan. Much of the Bengal Assam Railway went to the then East Pakistan (now Bangladesh). Exchanging assets and staff dislocates all normal work, as does the large-scale movement of people between India and Pakistan.
