The EAR 59 class was a class of oil-fired 1,000 mm (3,28 ft) gauge Garratt-type articulated steam locomotives. The 34 members of the class were built by Beyer, Peacock & Co. in Manchester, England, for the East African Railways (EAR). They entered service in 1955–56, and were the largest, heaviest and most powerful steam locomotives to operate on any metre gauge railway in the world.
