The Kollam–Sengottai railway line (formerly known as Quilon–Shencottah or Quilon–Chenkotta line) is a railway line in South India which connects Kollam Junction in Kerala state and Sengottai (also spelled Shencottah, Shenkottai, Chengottai, Chenkottai, Senkottai) in Tamil Nadu. The Quilon–Shencottah railway line was the first railway line in the erstwhile Travancore state and is more than a century old. The Kollam–Sengottai section is part of the Kollam–Chennai metre-gauge rail route commissioned by the British in 1904. The line has been completely converted to broad gauge and is now fully operational from Kollam Junction to Shengottai. It is going to be the important cargo transportation line connecting Vizhinjam container port and South Indian States.

History

The Kollam–Sengottai metre-gauge line was conceived and implemented by Maharajah Uthram Thirunal of Travancore. It was built jointly by South Indian Railway Company, Travancore State and the Madras Presidency. After a survey in 1888, work started in 1900 and was completed by 1902. The first goods train travelled on this route in 1902 while the first passenger train began its run in 1904. Metre-gauge services were inaugurated on 1 July 1904 with the first passenger train flagged off from Kollam by Maharajah Moolam Thirunal of Travancore with a 21-gun salute. The railway line was constructed by the British in the foothills of the Western Ghats to transport forest products, spices and cashews from Kollam to Chennai, their southern headquarters.

On 2024 July 28, the Palaruvi Express from Tirunelveli to Palakkad was the first electric train that passed through the route.^[11] The electric supply was obtained from Sengottai and Perinad traction substations.

About the route

The route was once a lifeline for the people of the southern districts of Kerala state and the Sengottai–Virudhunagar belt of Tamil Nadu. It served to create a strong link especially among the trading community of these areas in the two States. British tea estates and coffee plantations thrived on the labour of tribesman living in the Thenmala forests and workers from Tamil Nadu. The railway line contributed much to the development of a plantation economy in this area. The farmers of the Shencottah-Virudhunagar belt depended on the trains to market their produce in south Travancore. Huge quantities of vegetables, groceries and dairy products such as curd were brought into Kollam district from Tamil Nadu by trains that plied the route. The Palaruvi and Kazhuthurutti waterfalls and the Thenmala eco-tourism centre are on the fringes of this line, and the Courtallam waterfalls at the destination make this route popular with nature lovers.^[12]

Notable landmarks on the route

13 Kannara Bridge

The Pathimoonnu Kannara Bridge or 13 Arch Bridge (Pathimoonu kannara palam) is a 108–year–old bridge at Kazhathuruthi. The bridge consists of 13 arches and is a major landmark on the Kollam–Sengottai railway line as well as a testimony to the architectural abilities of the British. The bridge connects two hillocks and stands on thirteen granite pillars each almost a hundred feet tall. Sandwiched by the Kollam-Thirumangalam National Highway on one side and the River Kazhuthurutti on the other, the bridge is 102.72 metres (337.0 ft) long and 5.18 metres (17.0 ft) tall.

Aryankavu–Puliyara (Kottavasal) tunnel

The Aryankavu tunnel links Aryankavu in Kerala with Bhagavathipuram in Tamil Nadu. The tunnel was completed in 1903 and is 680 metres (2,230 ft) long. On both sides of the tunnel, the conch shell symbol of the Travancore rulers has been imprinted.

Popular metre-gauge trains on the route

Train No:6105/6106 (earlier 105/106) Kollam–Chennai Egmore Mail

This train was introduced in 1904 after the completion of the Quilon–Sengottai–Virudhunagar metre-gauge line and was flagged off by the then Maharaja of Travancore, Moolam Thirunal. The train was later renamed the Quilon–Madras Mail. The train was extended to Trivandrum in 1918 after completion of the Quilon–Trivandrum metre-gauge line. This train was one of the early metre gauge trains to have a First Class. The train was truncated at Quilon after the Kollam–Trivandrum Central metre-gauge track was converted to broad gauge in 1979. The train went through to Madurai Junction railway station via Manamadurai Junction from 1996 when the Virudhunagar–Madurai line was converted to broad gauge. The train was discontinued in June 2000.

Train No:6383/6384 Tirunelveli–Kollam Express
Sengottai–Kollam passenger

This passenger train was the main means of transport among office workers and students along this route.

Broad gauge conversion

The Punalur–Sengottai section is part of the 325-km Kollam–Sengottai–Tenkasi–Tirunelveli–Tiruchendur broad gauge conversion project and part of the Tenkasi–Virudhunagar trunk route to Chennai. The broad gauge conversion section has been completed.

Kollam–Punalur section

The Kollam Junction–Punalur metre-gauge railway line to broad-gauge conversion works foundation stone was laid in 1998 at Punalur. Services on the Punalur–Kollam metre-gauge section were withdrawn on 1 May 2007, to facilitate the broad gauge conversion work. The gauge conversion took almost 11 years to complete after the foundation stone was laid. The 44 km line was converted to broad gauge and inaugurated on 10 May 2010. Passenger train services connecting Punalur to Kollam, Madurai, Guruvayur, Kanyakumari and Palakkad Junction are currently operational in this route.^[1]

Punalur–Sengottai section

To facilitate the broad gauge conversion work on the Punalur–Sengottai section, train services on the section were withdrawn in September 2010. The 49.2-km Punalur–Sengottai section gauge conversion works were completed in December 2017 and the line was commissioned in March 2018. The inaugural Tambaram–Kollam special train (06027) ran through the section on 31 March 2018. The inaugural TBM–QLN special train was later extended to Chennai Egmore (MS) and then regularised w.e.f. 04.03.2019 where the inaugural run of the regular daily express train was flagged off. The regular train is 115 years old and re-started after 19 years. The train MS<>QLN EXP has train numbers 16101 (MS–QLN)/16102 (QLN–MS). The inaugural special run of the regular train had 06101 as the number and had a total of 14 coaches with 8 SL coaches & 2 3A coaches.

Major Trains

The major trains passing through this line are:

Chennai Egmore–Kollam Junction Express (Quilon Mail)
Ernakulam - Velankanni Express
Palaruvi Express
Guruvayur - Madurai Express

Future Projects

Improvements in track and track alignment is necessary to increase the speed and capacity of trains. Currently the trains with less bogies are moving at low speed with banker locos attached since this is a ghat section. The length of platforms at various stations are required to be increased to facilitate stoppage of long trains.
The doubling of the line is necessary because the line is shortest path from Kollam to Chennai and cargos from upcoming Vizhinjam Port (Thiruvananthapuram) will be travelling through this line.
Extensions of Sabari Railway Line:

The first phase of Sabari rail line is up to Erumely. As a second phase a railway line is proposed from Erumeli to Punalur. This facilitates the connection of Kollam- Sengottai line to Sabarimala, Pathanamthitta and to Ernakulam - Shornur line bypassing Kottayam, Alappuzha, Ernakulam.
Third phase extension from Punalur to Nemom / Balaramapuram (Proposed Vizhinjam port line starts from here).^[13] This railway will act as bypass line to Kollam-Thiruvananthapuram line. This line is beneficial to people in the highrange region of Kollam and Thiruvananthapuram districts. Also this line will facilitate the cargo movement from Vizhinjam Port.
