The site of the railway station hosted a fortified redoubt in the early 18th century, and later housed a
sanatorium, and an
orphanage in the mid 18th century. By the late 19th century, part of the land was owned by
Pulney Andy (1831–1909), one of the first Indians to earn a medical degree in the United Kingdom. The
South Indian Railway (SIR) was established in 1874 through the amalgamation of three railway companies that existed in the
Madras Presidency. Egmore became the company's terminus in Madras by the 1880s. An increase in traffic led to plans for the construction of a full-fledged terminus in the early 1900s. The terminal building was designed by British architects
Henry Irwin and E. C. Bird. It measured by , and was constructed by
T. Samynada Pillai. The construction of the station began in September 1905 and was completed in 1908 at a cost of . The station was opened to the public on 11 June 1908, and initially relied on
diesel generators for electricity. The station underwent developments in 1930, and became part of the first
electrified suburban line established in 1931. A signal cabin at the station was opened in 1935, after the suburban line between
Madras Beach and was electrified. After the nationalisation of the railways in 1951, the station became part of the
Southern Railway zone of the
Indian Railways, and emerged as a major terminal for trains to the south of the state. The
suburban trains continued to operate on meter gauge until 2004 when a new suburban terminal was added to the station. In 2013,
ballast-less tracks were laid along the terminus. In the early 2020s, it was one of the stations selected for upgradation under the
Amrit Bharat scheme of the Indian Railways, and underwent major renovation as a part of the scheme. ==Design==
