The Chennai Egmore–Thanjavur main line connects Chennai Egmore and Thanjavur Junction both in the Indian state of Tamil Nadu. The Chennai Egmore – Thanjavur main line is part of Chennai – Viluppuram – Thanjavur – Tiruchirappalli line. There are several branch lines (included here): Chengalpattu – Arakkonam (links to Chennai Central-Bengaluru City line, Guntakal-Chennai Egmore section), Viluppuram – Puducherry, Cuddalore – Virudhachalam, Mayiladuthurai – Thiruvarur, and Peralam – Nagapattinam sectors. The line connects the Kaveri delta to Chennai.

History

The "main line" of the metre gauge railway system in the Coromandel coast connected Chennai with Tiruchchirappalli via Viluppuram, Cuddalore, Mayiladuthurai (Mayavaram) and Thanjavur junctions.[1] The Chennai – Thanjavur – Tiruchirappalli line continues to be thought of as the "main line".[2][3]

In 1861 the Great Southern Railway of India built the 125 km (78 mi) long 1,676 mm (5 ft 6 in) wide broad gauge line between Nagapattinam and Tiruchirapalli (then known as Trichinopoly) and the line was opened to traffic next year.[4] It was a new development south of Chennai. After taking over of GSIR by South Indian Railway Company in 1874, the Nagapattinam – Tiruchirapalli line was converted to 1,000 mm (3 ft 3 3⁄8 in) wide metre gauge in 1875.[5]

The South India Railway Company laid a 715 km (444 mi) long metre gauge trunk line from Chennai to Thoothukudi via Mayiladuthurai and Thanjavur in 1880.[6] The 82.67 km (51 mi) long Tindivanam-Cuddalore Port (then known as Cuddalore Junction) sector, 27.60 km (17 mi) long Cuddalore Port-Porto Novo sector, 19.71 km (12 mi) long Shyali-Mayiladuthurai sector and 70.42 km (44 mi) long Mayiladuthurai-Thanjavur setor were opened in 1877, thereby connecting Tindivanam to the already opened Tiruchirappalli-Nagapattinam line.[7]

Following an agreement between the British and the French, a metre gauge line was laid between Puducherry and Viluppuram around 1877–1879.[5]

A 1,067 mm (3 ft 6 in) wide line was laid between Arakkonam and Kanchipuram (then known as Conjeevaram) in 1865 by Indian Tramway Company.[4] The line was converted to metre gauge in 1878 and opened in 1891. The Chengalpattu-Walajabad line was opened in 1880.[7]

Viluppuram was connected to Vriddhachalam railway station in 1927.[7]

The Mayiladuthurai-Tarangambadi line was opened in 1926 and was closed in 1987.[8]

Suburban railway

A major part of the South Line, Chennai Suburban is part of this line. The area south of Chennai was served by a single line shared by passenger and goods trains till 1931. Electric trains in the sector were planned as early as 1923. Construction work began in 1926 and was completed in 1931. A new line for electric trains was added between Chennai Beach and Egmore, and two lines were added between Egmore and Tambaram.[9] The first MG EMU services were run on 1.5kV DC overhead lines on 11 May 1931.[10] In the 1960s the Chennai Beach – Tambaram – Viluppuram sector was converted from 1,5 kV DC traction to 25 kV AC traction and limited EMU services were extended to Chengalpet. In 1969, an additional metre gauge track was laid between Tambaram and Chengalpet. Starting with the 1990s the entire area was converted to broad gauge.[10]

Gauge conversions

With the conversion from metre gauge to broad gauge, the entire Egmore-Tambaram-Tiruchirapalli-Dindigul-Madurai sector virtually complete, broad gauge passenger traffic was initiated in March 2001. The left over conversion work was then completed and the last metre gauge EMU service ran between Tambaram and Egmore on 1 July 2004.[11]

Conversion from metre gauge to broad gauge of the Viluppuram – Puducherry branch line was completed in 2004. The Cuddalore Port Junction railway station – Vadalur sector was converted in 2003.[12] After conversion work of the Thanjavur – Tiruvarur broad gauge section was opened to traffic in 2006 and Tiruvarur – Nagore section in 2010.[13]

Conversion from metre gauge to broad gauge of the Viluppuram-Cuddalore Port-Mayiladuthurai track was completed in 2010.[14]

A broad gauge line (conversion from metre gauge) connecting Chengalpattu with Arakkonam was built in 1999–2000. The Thakolam-Arakkonam sector had to be realigned because of its proximity to the Arakkonam Naval Air Station[15][16]

Electrification

The metre gauge track of Madras Beach-Tambaram sector was electrified in 1931 with 1.5 kV DC overhead system. In the fifties Indian Railways decided on using 25 kV AC overhead system on a national basis. The Madras Beach-Tambaram sector was converted to 25 kV AC overhead system in 1967.[17][18]

The Tambaram-Chengalpattu-Viluppuram sector was electrified in 1964–65 and then again in 2000-01 (after gauge conversion) along with the Chengalpattu-Kanchipuram sector.[18]

The broad gauge Viluppuram-Puducherry line was electrified in 2006.[19]

The broad gauge Viluppuram-Tiruchirapalli sector was electrified in 2010.[20]

New electrification survey in 2012–13 had been sanctioned in the Railway budget for the Karaikkal/Karaikkal port-Thiruvarur-Thanjavur-Tiruchchirappalli and Nagapattinam-Velankkani sectors.[21]

The execution of Electrification of Villupuram – Cuddalore Port – Mayiladuturai –Thanjavur and Mayiladuturai –Thiruvarur has been given to Rail Vikas Nigam Limited.[22]

Railway reorganization

The Great Southern Railway of India and Carnatic Railway merged to form South Indian Railway Company in 1874.[5]

In the early 1950s legislation was passed authorizing the central government to take over independent railway systems that were there. On 14 April 1951 the Madras and Southern Mahratta Railway, the South Indian Railway Company and Mysuru State Railway were merged to form Southern Railway. Subsequently, Nizam's Guaranteed State Railway was also merged into Southern Railway. On 2 October 1966, the Secunderabad, Solapur, Hubli and Vijayawada Divisions, covering the former territories of Nizam's Guaranteed State Railway and certain portions of Madras and Southern Mahratta Railway were separated from Southern Railway to form the South Central Railway. In 1977, Guntakal division of Southern Railway was transferred to South Central Railway and the Solapur division transferred to Central Railway. Amongst the seven new zones created in 2010 was South Western Railway, which was carved out of Southern Railway.[23]
