Class 21 was first introduced to Malaysia in 1965. It was suppose to be used for the East Coast line where 20 class cannot enter. It was built by the now defunct Kisha Keiso Kasha Ltd, Japan. This is the only mainline diesel-hydraulic locomotive used by KTMB. Because of the light axle weight, the locomotive experiences wheel slip very often.
This class has been withdrawn from service. There is one class 21 locomotive numbered 211.11 displayed at a park in Malacca city. There is another loco rotting away at a siding in Seremban station. I kinda like this 21 class design, reminds me of my Ultraman. Unfortunately i've never see one run in real life before. This locomotive produces 1060 horsepower. The tractive effort is 34,940.
