34 of the huge class 59 Garratts were built by Beyer Peacock in 1955 for the East African Railways (EAR) and dominated traffic on the Mombasa to Nairobi route for more then 20 years, able to pull 1200 ton trains on gradients of 1.5 %. They were the world's most powerful narrow gauge steamlocomotives ever built. Nowadays # 5930 "Mount Shengena" is exhibited in the Nairobi Railway Museum, while # 5918 "Mount Gelai" ist operational again since 2005. Unfortunately # 5918 failed with a charter train for Geoff's Trains/Tanago a few kilometres outside Nairobi station near Mombasa Road, perhaps because of a broken superheater pipe.
