History



Background


In order to replace steam locomotives and also to increase the diesel locomotive fleet of SLR, 16 diesel-electric locomotives were ordered from Hitachi and were delivered in 1979.



Decline


After few years of operation, due to technical problems, M5 class locomotives were taken out of service.[2]



Sub-Classes


Considering the decline of original Class M5 locomotives, SLR refurbished some selected M5 locomotives as a part of the Transportation Rehabilitation Project.[2] Refurbished locomotives were allocated in to 3 classes namely, M5A, M5B and M5C.























Sub Class Image Description
M5A M5 No. 769 was fitted with a new prime mover of model MTU V12 396TC13[1] which was a spare prime mover of a S8 DMU. Condemned due to an electrical failure.
M5B Class M5B.jpg 4 locomotives (Nos 768, 772, 777 and 778) were fitted with new Paxman Valenta V12 RP200L prime movers. In Use.
M5C M5class.jpg The M5 locomotives 767, 771, 776, 779, 781, 782 and 775 were fitted with new Caterpillar prime movers. This new locomotive class was called M5C. This class M5Cs known to Sri Lankan railway enthusiasts as "Cat"

Locomotives 773 and 780 were damaged due to accidents. Both are out of service. The last M5C locomotive was released in 2010. This locomotive was fitted with air brakes.[2]
