Introduced in 1955, these magnificent locos were the largest, heaviest and most powerful steam locos ever to be operated on the metre gauge. Capable of hauling a 1200 ton load up a 1 in 75 gradient the 34 members of the class, numbered 5901 - 5934, were named after the highest peaks in East Africa. Mount Gelai was withdrawn in 1980 and entered the museum under its own steam.
After 21 years as a static exhibit, Mount Gelai has been restored to full working order.
