The EAR 59 class is a class of oil-fired {{Track gauge|1000mm}} gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives. The 34 members of the class were built by Beyer, Peacock and Company 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.{{sfn|Ramaer|1974|pp=72–73}}

Design and service history

The locomotives had a {{Whyte|4-8-2+2-8-4}} wheel arrangement, weighed {{cvt|252|t|LT ST}}, and delivered a tractive effort of {{convert|83350|lbf|kN|2|abbr=on}}. They were designed to haul 1,200-ton trains on 1.5% gradients and were the mainstay of freight services on the {{cvt|330|mi|km}} run from Mombasa to Nairobi until the late 1970s.

During normal service, the locomotives were attended to by two regular crews on a 'caboose' basis, one working and one resting in a van with sleeping accommodation, changing over at eight-hour intervals.

The engines, many with Sikh drivers, were kept very clean and well maintained. The most famous of the 59 class was 5918 Mount Gelai with a devoted crew known as the 'Magnificent Foursome' who worked on it for 16 years. The two drivers, Kirpal Singh and Walter Pinto, simply went on holiday when the locomotive went into Nairobi works for scheduled maintenance.

According to railway photographer Colin Garratt (in 1975), "the overall condition of Mount Gelai is possibly unrivalled anywhere in the world today. Her cab interior is more akin to a Sikh temple than a locomotive footplate for its boiler face abounds in polished brasswork, embellished with mirrors, clocks, silver buckets and a linoleum floor".{{cite book|last=Garratt|first=Colin|title=Steam Safari |year=1974}}

Withdrawals started in 1973, with the last locomotive (Mount Gelai) removed from service in April 1980 when it was driven by its long time driver, Kirpal Singh directly to the Nairobi Railway Museum; Mr. Singh retired from railway service the same day. Together with Mount Gelai, Mount Shengena was also saved from scrap and both are now preserved by the Nairobi Railway Museum.

In August 2001, Mount Gelai was transferred from the Nairobi Railway Museum to the Kenya Railways' main works for an overhaul to working order. Between November 2001 and September 2005 the locomotive made three round trips to Mombasa hauling excursion trains. It was also used on at least one occasion to haul a freight train to Nairobi due to a shortage of diesel locomotives. However, it has not operated outside of Nairobi since 2005 and is unlikely to do so again due to operational restrictions and the partial regauging of Kenya's meter gauge ({{RailGauge|1000mm}}) rail lines to standard gauge (Standard-gauge railway).

In fiction

The 2018 Thomas & Friends special Big World! Big Adventures! introduced the character Kwaku, who is based on the EAR 59 class.{{Citation needed|date=September 2024}}

Names

The locomotives were named after mountains in East Africa:
