History

The first train in India from Chhatrapati Shivaji Terminus in Mumbai to Thane ran on 16 April 1853 on a track laid by the Great Indian Peninsula Railway. The GIPR line was extended to Kalyan in 1854 and then on the south-east side to Khopoli via Palasdari railway station at the foot of the Western Ghats in 1856. While construction work was in progress across the Bhor Ghat, GIPR opened to public the Khandala-Pune track in 1858. The Bhor Ghat incline connecting Palasdari to Khandala was completed in 1862, thereby connecting Mumbai and Pune.[1] GIPR extended its line to Raichur in 1871 and met the line of Madras Railway thereby establishing direct Mumbai-Chennai link.[2]

The first train service in southern India and the third in India was operated by Madras Railway from Royapuram / Veyasarapady to Wallajah Road (Arcot) in 1856. Madras Railway extended its trunk route to Beypur / Kadalundi (near Calicut) and initiated work on a north-western branch out of Arakkonam in 1861. The branch line reached Renigunta in 1862.[1] The branch line out of Arakkonam reached Raichur in 1871, where it connected to the Great Indian Peninsula Railway line from Mumbai.[2]

Electrification

The Kalyan-Pune section was electrified with 1.5 kV DC overhead system in 1930 [3] and was converted to AC overhead system in 2010.

The Pune-Solapur-Wadi line is being electrified with a loan of Rs. 1,500 crore from Asian Development Bank. Work was initiated in 2012.[4][5]

Electrification work is in progress in the Pune-Wadi-Guntakal sector. As on 1 April 2012 the entire route of 641 km was shown as balance work.[6]

Electrification of the 308 km long Renigunta-Guntakal section was announced in 2003 at a cost of Rs. 168 crore. The Renigunta-Nandalur sector electrification was completed in 2006.[7][8] The Nandalur-Guntakal sector was electrified by 2012.[6]

The Chennai Beach-Tambaram sector was electrified with DC overhead line in 1931 and was converted to 25 kv AC in 1967. The Chennai Central-Tiruvallur sector, as well as the Basin Bridge-Chennai Beach sector were electrified in 1979-80. The Tiruvallu-Arakkonam sector was electrified in 1982-83, Arakkonam-Tiruttani sector in 1983-84 and the Tiruttani-Renigunta sector in 1984-85.[9]
