Class 24 was built by Toshiba Electric Co, Japan. It was introduced to Malaysia in 1987. It is still in service. There are a lot of this class locomotives in service. It can be seen everywhere in the KTMB system. Just like class 23, this locomotive too uses Pielstick engine. This loco produces a whopping 2400 horsepower. The most powerful loco in KTMB until the 29 class locomotives arrived. The 29 class produces 3450 horsepower. Not sure if this is a rumour but a reliable source told me that his 24 class locos arrived in Malaysia with more than 3000HP but it had to be reduced because of overheating problem. Don't you think it's kinda funny that 24 class has got exactly 2400HP? There is something fishy about that coincidence. Anyway, class 24 locomotives has a top speed of 120KM/h.
