The TR NZ class, later known as the EAR 22 class, was a class of 1,000 mm (3 ft 3 3⁄8 in) 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. [2]

4-8-0 locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 4-8-0 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Mastodon and sometimes as the Twelve-wheeler.

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.

Nasmyth, Gaskell and Company defunct British locomotive manufacturer

Nasmyth, Gaskell and Company, originally called The Bridgewater Foundry, specialised in the production of heavy machine tools and locomotives. It was located in Patricroft, in Salford England, close to the Liverpool and Manchester Railway, the Bridgewater Canal and the Manchester Ship Canal. The company was founded in 1836 and dissolved in 1940.

Service history

In March 1916, while the four members of the class were on their way to India, they were commandeered to assist in the British invasion of German East Africa, where they entered service with the Tanganyika Railway (TR), still carrying their NGSR lettering and numbers 1095–1098. In the early 1930s, they were officially classified as the TR's NZ class (the NZ being a reference to "Nizam"), and renumbered as 200–203. [3]

German East Africa former German colony in the African Great Lakes region

German East Africa (GEA) was a German colony in the African Great Lakes region, which included present-day Burundi, Rwanda, and the mainland part of Tanzania. GEA's area was 994,996 square kilometres (384,170 sq mi), which was nearly three times the area of present-day Germany, and double the area of metropolitan Germany then.

The class was later operated by the TR's successor, the East African Railways (EAR), as its 22 class, numbers 2201–2204. In the late 1940s, two of them were transferred to the Southern Province Railway, an isolated network developed to support the ultimately unsuccessful Tanganyika Groundnut Scheme. Nos 2202 and 2204 were scrapped in 1952, and 2201 and 2203 in 1956. [4]

The Southern Province Railway was a 2 ft narrow gauge rail network in Tanzania, which was operated only for a few years in the middle of the 20th Century. It ultimately comprised about 275 route kilometers. The central line of the railway network was Mtwara - Nachingwea. The isolated network operated without connection to the national network. Because of the failure of the Tanganyika Groundnut Scheme the rail system was deprived of its economic existence. After the independence of Tanzania, operations were ceased in February 1963 and the line was abandoned.

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).

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.
