In 1955 the state owned Ceylon Government Railway, now the Sri Lanka Railways, manufactured Sri Lanka's "first" diesel-electric locomotive using old spares of withdrawn Class S1 DMU power sets. This locomotive was named as "Jayanthi" and classified Class M3 - 589. The locomotive was put to service on 5 September 1956. Two years later, in 1958, the then Ceylon Government Railway manufactured another locomotive and Classified it as Class M3 590.
