The [[metre-gauge]] Podanur–Mettupalayam line was opened to traffic in 1873. The UNESCO heritage track, [[Nilgiri Mountain Railway]] was opened in two stages. The Mettupalayam–Coonoor section was opened in 1899 and it was extended up to Udhagamandalam (Ooty) in 1908. The Podanur–Mettuapalayam section was converted to broad gauge in early 2000s.

Two 762 mm (2 ft 6 in)-wide [[narrow gauge]] famine-protective lines were opened in the early years of the twentieth century. The 25.25 mi (41 km)-long Tirupattur–Krishnagiri line was opened in 1905 and the 18.5 mi (30 km)-long Morappur–Dharmapuri line was opened in 1906 and extended to Hosur – 54.5 mi (88 km) long. The Hosur–Dharmapuri line was decommissioned in 1941 and other two lines were closed around 1945.

The 229 km (142 mi)-long 1,000 mm (3 ft 3+<sup>3</sup>⁄<sub>8</sub> in)-wide [[metre-gauge]] Salem–Bangalore line was opened in 1969. It was converted to [[5 ft 6 in gauge railway|5 ft 6 in]] (1,676 mm) [[broad gauge]] in 1997.
