Southern Railway, in its present form, came into existence on 14th April 1951 through the merger of the three state railways namely Madras and Southern Mahratta Railway, the South Indian Railway and the Mysore State Railway.

Southern Railway’s present network extends over a large area of India’s Southern Peninsula, covering the states of Tamilnadu, Kerala, Pondicherry and a small portion of Andhra Pradesh. Serving these naturally plentiful and culturally rich southern states, the Southern Railway extends from Mangalore on the west coast and Kanniyakumari in the south to Renigunta in the North West and Gudur in the North East.
