The KUR EC4 class, later known as the EAR 54 class, was a class of 1,000 mm (3 ft 3 3⁄8 in) gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives developed under and for use in wartime conditions.

Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-8-2+2-8-4 is a Garratt articulated locomotive consisting of a pair of 4-8-2 engine units back to back, with the boiler and cab suspended between them. The 4-8-2 wheel arrangement has four leading wheels on two axles, usually in a leading bogie, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. Since the 4-8-2 type is generally known as a Mountain, the corresponding Garratt type is usually known as a Double Mountain.

Garratt articulated steam locomotive with power unit at each end, and boiler slung between

A Garratt is a type of steam locomotive that is articulated into three parts. Its boiler is mounted on the centre frame, and two steam engines are mounted on separate frames, one on each end of the boiler. Articulation permits larger locomotives to negotiate curves and lighter rails that might restrict large rigid-framed locomotives. Many Garratt designs aimed to double the power of the largest conventional locomotives operating on their railways, thus reducing the need for multiple locomotives and crews.

Articulated locomotive

The term "articulated locomotive" usually means a steam locomotive with one or more engine units which can move independent of the main frame. This is done to allow a longer locomotive to negotiate tighter curves. Articulated locomotives are generally used either on lines with extreme curvature—logging, industrial, or mountain railways, for example—or to allow very large locomotives to run on railways with regular track curvature. Articulation is also applied to some electric locomotives, such as the Italian FS Class E656.

The seven members of the class were built during the latter stages of World War II by Beyer, Peacock & Co. in Manchester, England, for the War Department of the United Kingdom and the Kenya-Uganda Railway (KUR). They entered service on the KUR in 1944, and were later operated by the KUR's successor, the East African Railways (EAR). [2]

Manchester City and metropolitan borough in England

Manchester is a city and metropolitan borough in Greater Manchester, England, with a population of 545,500 as of 2017. It lies within the United Kingdom's second-most populous built-up area, with a population of 3.2 million. It is fringed by the Cheshire Plain to the south, the Pennines to the north and east, and an arc of towns with which it forms a continuous conurbation. The local authority is Manchester City Council.

War Department (United Kingdom) British Government ministry responsible for the Army

The War Department was the United Kingdom government department responsible for the supply of equipment to the armed forces of the United Kingdom and the pursuance of military activity. In 1857 it became the War Office. Within the War Office, the name 'War Department' remained in use to describe the military transport services of the War Department Fleet and the War Department Railways.

KUR EC3 class

The KUR EC3 class, later known as the EAR 57 class, was a class of 1,000 mm gauge 4-8-4+4-8-4 Garratt-type articulated steam locomotives. The twelve members of the class were built by Beyer, Peacock & Co. in Manchester, England, for the Kenya-Uganda Railway (KUR). They entered service between 1939 and 1941, and were later operated by the KUR's successor, the East African Railways (EAR).

The EAR 58 class was a class of 1,000 mm gauge 4-8-4+4-8-4 Garratt-type articulated steam locomotives built by Beyer, Peacock & Co. in Manchester, England, in 1949.

The KUR EC class was a class of 1,000 mm gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives. The four members of the class, built by Beyer, Peacock & Co. in Manchester, England, were the first Garratts to be ordered and acquired by the Kenya-Uganda Railway (KUR). They entered service in 1926, and, after a relatively short but successful career with the KUR, were sold and exported to Indo-China in August 1939.

The KUR EC1 class, later known as the EAR 50 class and the EAR 51 class, was a class of 1,000 mm gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives.

The KUR EC2 class, later known as the EAR 52 class, was a class of 1,000 mm gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives.

The TR GA class, later known as the EAR 53 class, was a class of 1,000 mm gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives. The three members of the class were built in 1930 by Beyer, Peacock & Co. in Manchester, England, for the Tanganyika Railway (TR). They entered service in 1931, and, with one exception, were later operated by the TR's successor, the East African Railways (EAR).
