The Sri Lanka Railways W2 is a class of diesel-hydraulic locomotives built by LEW Hennigsdorf for Sri Lanka Railways.

The rail vehicle factory in Hennigsdorf, Germany, was founded in 1910 by AEG. Locomotive production began in 1913, and in the 1930s absorbed the work of the August Borsig locomotive factory, being renamed the Borsig Lokomotiv Werke GmbH until 1944. After the Second World War the factory was nationalised in the German Democratic Republic and produced electric locomotives for home use and for export, mainly to Communist Bloc countries under the name Lokomotivbau-Elektrotechnische Werke (LEW).

Sri Lanka Railways

The Sri Lanka Railway Department is Sri Lanka's railway owner and primary operator. As part of the Sri Lankan government, it is overseen by the Ministry of Transport. Founded in 1858 as the Ceylon Government Railway, it operates the nation's rail and links the capital, Colombo, with other population centres and tourist destinations.

Description

Introduction

15 Class W2 locomotives were developed by LEW Hennigsdorf including a prototype according to the order placed by Sri Lanka Railways. 14 locomotives were delivered to Sri Lanka in 1969. Prototype locomotive was kept with the builder. Later by 1972, prototype locomotive also was delivered to Sri Lanka. First locomotive fleet were allocated the numbers 703 to 716. Last locomotive delivered was given the number 729. [2]

Operation

The class were used for working passenger and freight services on the SLR Main Line. [2]

Main Line (Sri Lanka)

The Main Line is a major railway line in the rail network of Sri Lanka and considered by many to be one of the most scenic train journeys in all of Asia. The line begins at Colombo Fort and winds through the Sri Lankan hill country to reach Badulla.

Declination

By 80's with the introduction of new locomotives, W2s were taken out of passenger services and were used on freight services. These have been on regular services until 1985. By 90's Most of locomotives were condemned due to technical failures. Some were scrapped. [2]

Class W2A

In 2015, SLR rebuilt W2 715. The new version has Paxman Valenta V12 prime mover. This is painted in a new livery. This locomotive is now in regular operations. [3]
