The class was ordered to strengthen the diesel locomotive fleet of Sri Lanka Railways. The Class M5 became a familiar sight on Main Line of SLR. They performed on Sri Lanka's railroad for few years. HistoryBackgroundIn 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. DeclineAfter few years of operation, due to technical problems, M5 class locomotives were taken out of service.[2] Sub-ClassesConsidering 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.
IncidentsLocomotives 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] See alsoDiesel locomotives of Sri Lanka{{Portal|Railways in Sri Lanka}}References1. ^1 2 3 {{cite web|url=http://slrailinfo.wordpress.com/locomotives/class-m/class-m5/ |title=Class M5 | Sri Lanka Railways Info Page |publisher=Slrailinfo.wordpress.com |date= |accessdate=2013-10-16}} 2. ^1 2 3 {{cite web|author= |url=http://locolanka.blogspot.com/2011/01/m5-made-in-japan.html |title=෴අඟුරු නොකා වතුර නොබී කොළඹ දුවන යකඩ යකා෴: ෴M5 දුම්රිය එන්ජිම - Made in Japan෴ |publisher=Locolanka.blogspot.com |date=2011-01-02 |accessdate=2013-10-16}}
