The Chennai Central – Bangalore City line is an electrified railway double line which connects the cities of Chennai and Bengaluru in South India.

History

The first train service in southern India and the third in India was operated by Madras Railway from Royapuram / Veyasarapady to Wallajah Road (Arcot) in 1856. Madras Railway extended its trunk route to Beypur / Kadalundi (near Calicut) in 1861. Madras Railway connected Bangalore Cantonment to Jolarpettai on the newly constructed Beypur line in 1864. Bangalore Mail started running the same year. Bangalore City was linked to Bangalore Cantonment in 1882. The 1,676 mm (5 ft 6 in)-wide 5 ft 6 in (1,676 mm) broad gauge Bangarpet-Marikuppam line came up in 1894. The 2 ft 6 in (762 mm)-wide narrow-gauge line between Bowringpet (later Bangarpet) and Kolar was opened in 1913 by Mysore State Railway. The narrow-gauge Yeshvantapur–Yelahanka–Devanahalli–Chikkaballapur–Kolar line was opened in 1915 and was linked to Bangalore in 1918. With the completion of the gauge conversion to broad gauge of the Chikballapur-Kolar section in November 2013, the entire Bangalore–Kolar section was ready for direct broad gauge trains. Gauge conversion of the Bangarpet–Kolar line was completed in 1997 and a Railbus service was operating since then, till 11 September 2016 when Railbus got replaced by an eight-bogie diesel–electric multiple unit (DEMU).

The Chennai–Tiruvallur sector was electrified in 1979–80, the Tiruvallur–Arakkonam–Chitteri sector in 1982–83, the Chitteri–Walajah Road (excl) sector in 1983–84, the Walajah Road–Katpadi sector in 1984–85, the Katpadi–Jolarpettai sector in 1985–86, the Jolarpettai–Mulanur sector in 1990–91, the Mulanur–Bangarpet–Bangalore City sector in 1991–92.

In the early 1950s legislation was passed authorizing the central government to take over independent railway systems that were there. On 14 April 1951 the Madras and Southern Mahratta Railway, the South Indian Railway Company and Mysore State Railway were merged to form Southern Railway. Subsequently, Nizam's Guaranteed State Railway was also merged into Southern Railway. On 2 October 1966, the Secunderabad, Solapur, Hubli and Vijayawada Divisions, covering the former territories of Nizam's Guaranteed State Railway and certain portions of Madras and Southern Mahratta Railway were separated from Southern Railway to form the South Central Railway. In 1977, Guntakal division of Southern Railway was transferred to South Central Railway and the Solapur division transferred to Central Railway. Amongst the seven new zones created in 2003 was South Western Railway, which was carved out of Southern Railway and South Central railway.
