The Chord Line connects Viluppuram Junction and Tiruchirappalli Junction, via Virudhachalam Junction in Tamil Nadu. It is the vital, shortest and busiest route connecting Chennai Egmore and Southern Tamil Nadu.

History

Until 1927, Viluppuram Junction and Tiruchirappalli Junction were only connected by Main line that traversed through Kumbakonam and Mayavaram, which was 240 kilometres (150 mi). Hence, the need for shorter route arose and construction began on 22 August 1927 for a new railway line via Virudhachalam Junction in phases. Initially, the stretch between Viluppuram Junction and Virudhachalam were completed and opened on 1 December 1927, the Srirangam - Golden Rock stretch on 22 August 1927, Bikshandarkoil - Srirangam stretch on 12 December 1927 and the entire stretch began its operations since 1 February 1929. This line gradually reduced the Madras - Colombo journey by around four hours. ^[3]

Gauge conversions

The conversion from metre gauge to broad gauge was effected during 1992-93 and completed during September 1998. ^[4]

Electrification

This stretch was proposed for electrification phase by phase by CORE. The electrification was completed during 2010. ^[5]

Operations

Passenger services

The line experiences a heaviest traffic ^[6] handling about 30 passenger and 56 express trains passing through every day in addition to goods train, particularly during night. ^{[7] [8] [9]}

Freight services

The line has a number of Industrial establishments ^[10] which utilises their nearby railway stations for their logistics and transports such as Central Workshop (Golden Rock), Cement and gypsum factories at Trichy, Perambalur and Ariyalur, ^{[11] [12] [13]} and the Sugar factories at Villupuram and Vridhachalam, ^[14]
