The South Eastern Railway (SER) is one of the 17 railway zones in India and Part of Eastern Railways. It is headquartered at Garden Reach, Kolkata, West Bengal, India. It comprises Adra railway division, Chakradharpur railway division, Kharagpur railway division and Ranchi railway division.

The Bengal Nagpur Railway (BNR) Company was incorporated in 1887 to take over from the Nagpur Chhattisgarh Railway and to convert the line to broad gauge. The work was completed in 1888. The extension of the main line from Nagpur to Asansol was completed by 1891. A 161-mile branch line (258 km) that connected Bilaspur to Umaria coal mine was built and linked to the existing line from Umaria to Katni (1891). By the turn of the twentieth century, work on the Calcutta–Bombay and Calcutta–Madras lines was completed. Through the first half of the twentieth century work on the BNR lines progressed steadily. In 1921 the Talcher coalfields were connected by a railway line starting from Nergundi. In 1931, the RaipurVizianagaram line was set up, which connected the east coast with the Central Province. By the end of the 1930s the BNR owned the largest narrow-gauge network in the country. The BNR management was taken over by the British Indian government on 1 October 1944. and continued to be called by that name until 14 April 1952, when it was amalgamated with the East Indian Railway to form one of six newly carved zones of the Indian Railways: the Eastern Railway.
