FMSR O Class

The O class is a Pacific class built for the Federated Malay States Railway by the North British Locomotive Company in Glasgow, Scotland and delivered in 4 batches between 1938 and 1948. Originally known as O1 Class, the first batch of 11 was delivered in 1938 and numbered 60 - 70. In 1939 a second, identical, batch of 6 was delivered as O2 class and numbered 71-76. The third batch of 11, known as O3 and numbered 77 - 87, was delivered in 1940 and differed in that the cylinder diameter was increased by ½" with a consequent increase in tractive effort. In 1946 a fourth batch, to be known as O4, was ordered but a new numbering scheme was introduced before delivery and they became the 564 class, the earlier locomotives becoming 561, 562 and 563 classes respectively. 40 of these were delivered between 1946 and 1948 and differed from the 563 (O3) class in having an extended tender front sheeting and roof providing an all-weather cab and slightly increasing length and weight.
The class were used on the country's top link express trains such as the Penang Mail. After the Second World War, the class members delivered in 1946 onwards were designated a part of a wartime recovery programme for Malaya after the destruction wreaked upon the nation by the Japanese. In commemoration of this, a few members of the class were painted a celebratory Great Western Railway Green livery complete with copper chimney caps.
In the 1970s, steam locomotives began to be withdrawn from Malaysia's railway systems
