The TR RV class, later known as the EAR 21 class, was a class of 1,000 mm (3 ft 3 3⁄8 in) gauge steam locomotives designed and built for the Tanganyika Railway (TR) as a 4-8-2 development of the 2-8-2 TR MK class. The eight members of the RV class were built by Vulcan Foundry, in Newton-le-Willows, Lancashire (now part of Merseyside), England.

Steam locomotive railway locomotive that produces its pulling power through a steam engine

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material – usually coal, wood, or oil – to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind.

4-8-2 locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 4-8-2 represents the wheel arrangement of four leading wheels, eight powered and coupled driving wheels and two trailing wheels. This type of steam locomotive is commonly known as the Mountain type.

Under the Whyte notation for the classification of steam locomotives, 2-8-2 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike.

The "RV" class designation was short for "River", as each RV class locomotive was named after a river in the Tanganyika Territory. The class entered service on the TR between 1928 and 1930, and its members were later operated by the TR's successor, the East African Railways (EAR). [2]

History of rail transport in Tanzania transport history

The history of rail transport in Tanzania began in the late nineteenth century.

Rail transport in Kenya consists of a metre-gauge network that is in poor condition and a new standard gauge railway (SGR). Both railways connect Kenya's main port city of Mombasa to the interior, running through the national capital of Nairobi. The metre-gauge network runs to the Ugandan border, and the Mombasa–Nairobi Standard Gauge Railway is being extended to the Ugandan border as of June 2017.

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 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).

KUR EA class class of 6 East African 2-8-2 locomotives

The KUR EA class, later known as the EAR 28 class, was a class of 1,000 mm gauge 2-8-2 steam locomotives. The six members of the class were built in 1928 for the Kenya-Uganda Railway (KUR) by Robert Stephenson and Company in Darlington, England, and were later operated by the KUR's successor, the East African Railways (EAR).

The EAR 29 class was a class of oil-burning 1,000 mm gauge 2-8-2 steam locomotives based upon the Nigerian Railways River class. The 31 members of the 29 class were built for the East African Railways (EAR) in two batches, of 20 and 11 locomotives respectively, by North British Locomotive Company in Glasgow, Scotland.

The EAR 30 class was a class of oil-burning 1,000 mm gauge 2-8-4 steam locomotives. The class was built in 1955 by North British Locomotive Company in Glasgow, Scotland, for the East African Railways (EAR). Its design was derived from the 2-8-2 EAR 29 class, which, in turn, was based upon the Nigerian Railways River class.

EAR 31 class class of 46 East African 2-8-4 locomotives

The EAR 31 class was a class of oil-burning 1,000 mm gauge 2-8-4 steam locomotives. The 46 members of the class were built in 1955 by Vulcan Foundry, in Newton-le-Willows, Lancashire, England, for the East African Railways (EAR). They were a lighter, branch-line version of the EAR 30 class, and worked from various sheds throughout the EAR system.

The TR DL class, later known as the EAR 23 class, was a class of 1,000 mm gauge 4-8-0 steam locomotives derived from the Nigerian Railways Emir class. The six members of the DL/23 class were built by Beyer, Peacock & Co. in Gorton, Manchester, England, for the Tanganyika Railway (TR). They entered service on the TR in 1923, and were later operated by the TR's successor, the East African Railways (EAR).

The EAR 27 class was a sub-class of 1,000 mm gauge 2-8-2 USATC S118 Class steam locomotives. The first eight members of the class were built in 1944, and were acquired second hand by the Tanganyika Railway (TR) from the Malayan Railways in 1949. By the time these eight locomotives entered service on the Central Line in Tanganyika in 1949, the TR had been succeeded by the East African Railways (EAR), which designated them for a very short time as its MR class, but then, as part of a comprehensive reclassification of all of its locomotives, redesignated them as its 27 class.

The EAR 12 class was a class of 1,000 mm gauge 2-6-2 T steam locomotives built by W. G. Bagnall in Stafford, England, in 1950. The class had been ordered by the Tanganyika Railway (TR) as its SS class, and was a modified and updated version of the TR's existing ST class.

The TR NZ class, later known as the EAR 22 class, was a class of 1,000 mm gauge 4-8-0 steam locomotives built in 1915 by Nasmyth, Wilson and Company in Patricroft, Salford, England. The class had been ordered by the Nizam's Guaranteed State Railway (NGSR) for operation on its network in the Dominion of Nizam, better known as the Hyderabad State, in India. However, the locomotives in the class were never delivered to the NGSR, and, in the end, served their entire working lives in Tanganyika, East Africa.
