The Kelani Valley Railway Line, in Sri Lanka, covering the breadth of Colombo District and some parts of Kegalla and Ratnapura Districts. The line is owned, maintained, and operated by Sri Lanka Railways.

Route definition and overview

Nugegoda Railway Station

The Kelani Valley Line runs southeast from Colombo Maradana Station, through much of the city of Colombo. It runs through major business centres, like Nugegoda and Maharagama, before turning eastwards. It crosses the Southern Expressway near Homagama and continues east towards Avissawella, the current terminus of the line. The line serves an increasingly urbanising community.

Major railway stations on the line are Colombo Fort, Maradana, Narahenpita, Nugegoda, Maharagama, Pannipitiya, Kottawa, Homagama, Meegoda, Padukka, Waga, Kosgama, and Avissawella.

History

Narrow gauge era

The Kelani Valley Line was originally built from Colombo to Yatiyanthota via Avissawella during 1900 - 1902. It was branched off at Avissawella and extended up to Opanayaka via Ratnapura (completed in 1912). Originally built as a 2 ft 6 in (762 mm) narrow gauge^[1] line to serve the rubber plantations in the area, the railway line between Avissawella and Yatiyanthota was removed in 1942, the line from Homagama to Opanayaka abandoned in 1973.

The services were restarted up to Avissawella in 1978.

Gauge conversion

In 1992, a project was started to convert the line to 1,676 mm (5 ft 6 in). The project was finally completed up to Avissawella (58 km or 36 mi) in 1996. The tracks beyond were completely abandoned and currently the tracks from Avissawella to Yatiyanthota and Opanayaka can only be traced by the remaining and ruined stations, bridges and bunds.

Infrastructure

The Kelani Valley Line is entirely single track, at 1,676 mm (5 ft 6 in).^[2] As train frequency increases, it is becoming increasingly challenging to operate trains running both direction on the single-line track.

Currently the line serves an increasingly urbanizing population leading up to Avissawella. Even though the line was broad-gauged to improve the services in capacity and speed, the objectives have not been achieved due to sharp curves (a leftover of the narrow gauge system) and the illegal constructions on either sides of the track from Colombo up to Maharagama.

The Kelani Valley Line is not electrified. All services run on diesel power. Current operating speeds are limited due to the sharp curves on the line.

Locomotives and rolling stock

New S12 DMUs were introduced in 2012

During the narrow gauge era, the line had its own fleet of narrow gauge locomotives and rolling stock. The steam locomotives of Class K and Sentinel railcars class V1 & V2 were also used.

Operation

Sri Lanka Railways has a monopoly on the operation of Kelani Valley Line.

As of January 1, 2009, there were 16 trains operating on the line daily, mainly catering for the rush hour commuters traveling to and from Colombo.
