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.^[3]

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."^[4]
