Southern Railway zone

The history of the Southern Railway can be traced back to the Madras Railway. In 1832, the proposal to construct the first railway line in India at Madras was made by the British. In 1835, the railway track was constructed between Little Mount and Chintadripet in Madras and became operational in 1837. The Madras Railway was established later in 1845 and the construction on the first main line between Madras and Arcot started in 1853, which became operational in 1856. In 1908, Madras Railway merged with Southern Mahratta Railway to form the Madras and Southern Mahratta Railway. In 1944, all the railway companies operating in British India were taken over by the Government. Post Independence, various re-grouping proposals were studied as there were 42 different railway systems. In December 1950, the Central Advisory Committee for Railways approved the plan for Indian Railways into six zonal systems and the Southern Railway zone was created on 14 April 1950 by merging three state railways, namely, the Madras and Southern Mahratta Railway, the South Indian Railway Company, and the Mysore State Railway. ==Organisation==
