The Nagpur–Hyderabad line is a railway line connecting Nagpur and Hyderabad. A major portion of this 581-kilometre long (361 mi) track, from Nagpur to Kazipet, is part of the Delhi-Chennai line. It is also part of the Delhi-Hyderabad line. The line is under the jurisdiction of Central Railway and South-Central Railway.
With the completion of the Kazipet-Balhashah link in 1929, Chennai was directly linked to Delhi.
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.
As of 1909, "From Wadi on the Great Indian Peninsula Railway, the Nizam's Guaranteed State Railway runs east to Warangal and then south-east towards Bezwada on the East Coast section of the Madras Railway."
The Kazipet-Ramagundam sector was electrified in 1987-88, the Ramagundam-Balharshah-Nagpur sector in 1988-89, the Kazipet-Secunderabad sector in 1991-93 and Majri-Rajpur sector in 1994-95.
