History

The Agra-Delhi chord was opened in 1904.[1] Some parts of it were relaid during the construction of New Delhi (inaugurated in 1927-28).[2]

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.[3]

The Bhopal-Itarsi line was opened by the Begum of Bhopal in 1884.[3] Itarsi was linked with Nagpur between 1923 and 1924.[4]

The period of construction of the Nagpur-Balharshah line is uncertain.

The Vijayawada-Chennai line was constructed in 1899.[3]

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]

With the completion of the Kazipet-Balharshah link in 1929, Chennai was directly linked to Delhi.[1]

Electrification

The Vijayawada–Chennai section electrified by 1980.[5]

The Vijayawada-Kazipet sector was electrified in 1985-88.[6]

The Kazipet- Ramagundam-Balharshah-Nagpur sector was electrified in 1987-89.

The Bhopal-Itarsi sector was electrified in 1988-89 and the Nagpur-Itarsi sector in 1990-91.

The Agra-Bhopal sector was electrified in 1984-89.

The Agra-Faridabad section was electrified in 1982-85.[6]

Speed limits

The Delhi–Chennai line (Grand Trunk route) is classified as a "Group A" line which can take speeds up to 160 km/h.[7]

Passenger movement

New Delhi, Mathura Junction, Agra Cantt., Gwalior, Jhansi, Bhopal, Bhopal Habibganj, Nagpur, Warangal, Ramagundam railway station, Vijayawada, Nellore and Chennai Central, on this line, are amongst the top hundred booking stations of Indian Railway.[8]

Diamond quadrilateral

The Delhi–Chennai line is a part of the diamond quadrilateral. The routes connecting the four major metropolises (New Delhi, Mumbai, Chennai and Kolkata), along with their diagonals, known as the diamond quadrilateral, carry about half the freight and nearly half the passenger traffic, although they form only 16 per cent of the length.[9]
