A Garratt locomotive is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage.
Beyer, Peacock and Company was an English railway locomotive manufacturer with a factory in Openshaw, Manchester. Founded by Charles Beyer, Richard Peacock and Henry Robertson, it traded from 1854 until 1966. The company exported locomotives, and machine tools to service them, throughout the world.
The Tasmanian Government Railways K class was a class of 0-4-0+0-4-0 Garratt locomotives operated by the Tasmanian Government Railways from 1909 – the first Garratt locomotives built.
The Australian Standard Garratt (ASG) was a Garratt locomotive designed in Australia during World War II, and used on 3 ft 6 in narrow gauge railway systems in Queensland, South Australia, Western Australia and Tasmania.
The Tasmanian Government Railways (TGR) was the former operator of the mainline railways in Tasmania, Australia. Formed in 1872, the railway company was managed by the Government of Tasmania, and existed until absorption into the Australian National Railways Commission in 1978.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, the 0-4-0+0-4-0 is an articulated locomotive of the Garratt type. The wheel arrangement is effectively two 0-4-0 locomotives operating back-to-back or face-to-face, with the boiler and cab suspended between the two power units. Each power unit has no leading wheels, four powered and coupled driving wheels on two axles and no trailing wheels. A similar arrangement exists for Mallet, Meyer and Fairlie locomotives, but is referred to as 0-4-4-0.
The NZR WF class were steam locomotives designed, built and used by New Zealand Railways (NZR). Their wheel arrangement is described by the Whyte notation 2-6-4T and the first members of the class entered service in 1904. The locomotives were tank engines designed by the Railways Department's Chief Mechanical Engineer A. L. Beattie, and were mainly built for suburban duties such as those between Christchurch and Lyttelton. They also saw main-line service in the Taranaki region, but most of the class members were assigned to branch line and local services throughout the country. Two were experimentally converted to oil burners in 1909-1910. The tests were satisfactory, but as coal was much cheaper than oil at the time, no further conversions took place.
Rail transport in Tasmania consists of a network of narrow gauge track of 1,067 mm reaching virtually all cities and major towns in the island state of Tasmania, Australia. Today, rail services are focused primarily on bulk freight, with no commercial passenger services being operated. The mainline railways of Tasmania are currently operated by TasRail, a Government of Tasmania-owned Corporation, who owns and maintains both rolling stock, locomotives, and track infrastructure.
The Sierra Leone Government Railway operated in Sierra Leone from 1897 to 1974. It was unusual in that it formed a national railway system constructed solely to a 2 ft 6 in narrow gauge, whereas in other countries, gauge of such a narrow width was usually confined to feeder railways.
The Y class is a class of diesel locomotives built by the Tasmanian Government Railways between 1961 and 1971.
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.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-4-2+2-4-4 is a Garratt articulated locomotive. The wheel arrangement is effectively two 4-4-2 locomotives operating back to back, with each power unit having four leading wheels on two axles in a leading bogie, four powered and coupled driving wheels on two axles, and two trailing wheels on one axle in a trailing truck. Since the 4-4-2 type is usually known as an Atlantic, the corresponding Garratt type is often referred to as a Double Atlantic.
The New South Wales AD60 class were Beyer-Garratt patent articulated four-cylinder, simple, non-condensing, coal-fired superheated, 4-8-4+4-8-4 heavy goods steam locomotives built by Beyer, Peacock & Company for the New South Wales Government Railways in Australia.
Frederick Mills was Chief Mechanical Engineer of the Western Australian Government Railways from 1940 until his death in 1949. He was seconded to the Federal Government during World War II and was known throughout his career for designing a number of the influential steam locomotives for operation in Western Australia, including a number of controversial designs. No fewer than four Royal Commissions were held into various aspects of WAGR operations – including an examination of the safety of the Australian Standard Garratt locomotive and other aspects pertinent to its design and development – during his tenure, all of them into issues against which Mills himself fought unceasingly.
The Emu Bay Railway was a Tasmania, Australian railway company. The railway was significant during full operation, in that it linked the Tasmanian Government Railways system at Burnie with that at Zeehan that further linked to the Mount Lyell railway allowing connection through to Queenstown.
The South African Railways Class NG G16 2-6-2+2-6-2 is a narrow gauge steam locomotive class.
The Tasman Limited was a passenger train operated by Tasmanian Government Railways (TGR) on the Main and Western lines between Hobart, Launceston and Wynyard from April 1954 to July 1978.
The Tasmanian Government Railways M class was a class of 4-4-2+2-4-4 Garratt steam locomotives operated by the Tasmanian Government Railways.
The Tasmanian Government Railways V class are a class of diesel locomotives operated by the Tasmanian Government Railways.
The Tasmanian Government Railways P Class was a 2-6-2T locomotive bought second hand from a timber company in New South Wales. It was withdrawn in c.1941; having spent the majority of its service in or around Launceston Workshops and Yards.
