Locomotives and train sets of Sri Lanka Railways consist mostly of diesel locomotives and multiple units. Steam locomotives are no longer used, except on heritage trains such as the Viceroy Special.

The first locomotives pulled trains on the original segment of the Main Line, on 54 kilometres (34 miles) connecting Colombo and Ambepussa. In 1953, Sri Lanka Railways enhanced its service to more power with diesel locomotives. Since then, various types of diesel locomotives were added to the service.

History

Sri Lanka's first railway locomotive was Leopold, introduced in 1864. It was one of seven 4-4-0 locomotives built that year for the Ceylon Government Railway by Robert Stephenson & Company (Nos. 1–5) and Beyer, Peacock & Company (Nos. 6 and 7). Many more steam locomotives were added to the system, through to the 1950s. All the steam locomotives but three were manufactured in the United Kingdom; the exceptions were three 4-4-0s built at the railway's Maradana Works near Colombo in 1900 and 1905. In 1938, locomotives were reclassified, based on wheel arrangement and gauge. Sub-classification was based on weight, modifications, heating type, boiler capacity, or other features.

Throughout its history, Ceylon Government Railway had 410 steam locomotives.

The Railways upgraded its service to diesel locomotives, under the leadership of B. D. Rampala in the mid 1950s. In 1953, the first locomotives from British builder Brush Bagnall were imported. Since then, the Railways have imported locomotives from Canada, Japan, West Germany, India, France, and China

In the 1990s, Sri Lanka Railways converted the 2 ft 6 in (762 mm) narrow gauge Kelani Valley line into 5 ft 6 in (1,676 mm) broad gauge. This was the last narrow gauge line left in Sri Lanka, and its conversion to broad gauge put the fleet of narrow gauge locomotives out of use. All operational locomotives in the country today are broad gauge.

As of March 2022, Sri Lanka does not have commercially operational electric locomotives or train sets. Electrification has been proposed to improve energy efficiency and sustainability.

Liveries

Sri Lanka's locomotives have appeared in several different liveries over the years.

The steam locomotives were mainly painted in black.

With the introduction of diesel locomotives, coloured liveries appeared. Typical for many locomotives is a livery that has thick horizontal bands of dark blue, light blue, silver and a yellow stripe. Also common for many locomotives is a livery of horizontal bands of green, brown, and a yellow stripe.

The DMUs are painted in various liveries, unique to their classes. Typically, they feature horizontal bands of colour running their entire length and a solid colour on the front and back ends.

ICE livery

M6 ICE locomotives have a unique ICE livery of brown and orange.

Numbering

Steam locomotives were numbered from 1 upwards, reaching 161 in 1911. Whereafter replacement locomotives were given the same number as the locomotive that they replaced with an "R" prefix; until such time as the old locomotive, now running with an "O" prefix, was finally withdrawn. This system was abandoned in 1928, with new locomotives being numbered from 249 upwards, and reaching 336 by 1940, and 362 in 1951 when the last steam locomotive — a 4-8-0 from WG Bagnall — was delivered.

Narrow gauge locomotives were numbered in the same list as broad-gauge locomotives. Diesel locomotives and multiple unit numbering started from 500 – an Armstrong Whitworth 122 hp 0-4-0 diesel-electric shunter delivered in 1934 – and reached 840 in 1991. and included one locomotive experimentally converted to electric traction.

Steam locomotives

Steam locomotives were used on regular services until the 1970s.
