Sri Lanka Railways M2
The Sri Lanka Railways Class M2 is a class of diesel-electric locomotive that was developed in 1954 by General Motors Diesel, Canada, and Electro-Motive Division, USA. This is considered one of the most successful locomotives in Sri Lanka.

It is a General Motors Diesel (Canada) EMD G12 model using the EMD 567C,  engine.

Description

Introduction
From 1954, several batches of General Motors-manufactured locomotives were imported to Sri Lanka under "The Colombo Plan". Locally called a "Canadian" engine – there are actually two classes of Canadian engines in SLR – the other one is Class M4. Since these engine were imported under grants from the Canadian government, class M2 locomotives are named with Canadian province and city names. The last two locomotives were made in the United States and imported for Cement Corporation, Sri Lanka. But they were later attached to Sri Lanka Railways’ locomotive fleet. They were named after two local cities – Galle and Kankasanthurei – where the cement factories were located.

Entering into Service
The class entered service in January 1955.  The Ruhunu Kumari train started using M2 572 British Columbia on 24 October 1955, the first long distance luxury passenger train service in Sri Lanka. The same loco hauled the first Udarata Manike Colombo - Badulla train on 23 April 1956, and on the same day the Yal Davi started, hauled by M2 569 Ontario, in the far north of the country.

Sub Classes

In Service
This class has been used on both passenger and freight trains on Sri Lanka's railways for over 50 years. Despite the introduction of more modern types of traction, as of 2013 a significant number are still in use.
