History
The Agra–Delhi chord was opened in 1904. Some parts of it were relaid during the construction of New Delhi (inaugurated in 1927–28).
The Agra–Gwalior line was opened by the Maharaja of Gwalior in 1881 and it became the Scindia State Railway.
The Indian Midland Railway built the Gwalior–Jhansi line and the Jhansi–Bhopal line in 1889.
The Bhopal–Itarsi line was opened by the Begum of Bhopal in 1884. Itarsi was linked with Nagpur between 1923 and 1924.
The period of construction of the Nagpur–Balharshah line is uncertain.
The Vijayawad–Madras line was constructed in 1899.
The Wadi–Secunderabad line was built in 1874 with financing by the Nizam of Hyderabad. It later became part of Nizam's Guaranteed State Railway. In 1889, the main line of the Nizam's Guaranteed State Railway was extended to Vijayawada, then known as Bezwada.
With the completion of the Kazipet–Balharshah link in 1929, Madras was directly linked to Delhi.
