A Fairlie locomotive is a type of articulated steam locomotive that has the driving wheels on bogies. It was invented by Robert Francis Fairlie. The locomotive may be double-ended or single ended. Most double-ended Fairlies had wheel arrangements of 0-4-4-0T or 0-6-6-0T. All were tank locomotives.
A Garratt locomotive is a type of articulated 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.
The first Locomotives of the Great Western Railway (GWR) were specified by Isambard Kingdom Brunel, but Daniel Gooch was soon appointed as the railway's Locomotive Superintendent. He designed several different 7 ft 1⁄4 in broad gauge types for the growing railway, such as the Firefly and later Iron Duke Class. In 1864 Gooch was succeeded by Joseph Armstrong who brought his standard gauge experience to the workshops at Swindon. To replace some of the earlier locomotives, he put broad gauge wheels on his standard gauge locomotives and from this time on all locomotives were given numbers, including the broad gauge ones that had previously carried just names.
Under the Whyte notation for the classification of steam locomotives, 0-6-4 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and four trailing wheels on two axles.
The North East Dundas Tramway was a 2 ft narrow gauge tramway, that ran between Zeehan and Deep Lead on the West Coast of Tasmania. Opening in 1896 and closing in 1932, it was part of the Tasmanian Government Railways network. The world's first Garratt locomotives, the K class, were used on the line.
Indian Railways operates India's railway system and comes under the purview of the Ministry of Railways of Government of India. As of 2023, it maintains over 108,706 km (67,547 mi) of tracks and operates over 13,000 trains daily with a fleet of 14,800 locomotives. The railways primarily operates a fleet of electric and diesel locomotives along with a few compressed natural gas (CNG) locomotives. Steam locomotives are operated on mountain railways and on heritage trains.
The London and North Eastern Railway Class U1 was a solitary 2-8-0+0-8-2 Garratt locomotive designed for banking coal trains over the Worsborough Bank, a steeply graded line in South Yorkshire and part of the Woodhead Route. It was both the longest and the most powerful steam locomotive ever to run in Britain. It was built in 1925 with the motion at each end being based on an existing 2-8-0 design. The original number was 2395, and it was renumbered 9999 in March 1946, and then 69999 after nationalisation in 1948, although it retained its cab-side plate bearing its original number throughout its life. The locomotive ran for some time as an oil burner, and was tried out on the Lickey Incline in 1949–1950 and again, after the electrification of its home line, in 1955. These trials were unsuccessful, and so the locomotive was withdrawn in 1955 and scrapped.
A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks. Installations vary depending on the purpose, design and the type of locomotive to which it is fitted. It differs from the usual closed cycle condensing steam engine, in that the function of the condenser is primarily either to recover water, or to avoid excessive emissions to the atmosphere, rather than maintaining a vacuum to improve both efficiency and power.
Under the Whyte notation for the classification of steam locomotives, 2-6-0+0-6-2 represents the wheel arrangement of an articulated locomotive with two separate swivelling engine units, arranged back to back with the boiler and cab suspended between them. Each engine unit has two leading wheels in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels.
The SLNCR Lough Class was a class of 0-6-4T steam tank locomotives of the Sligo, Leitrim and Northern Counties Railway (SLNCR).
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.
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.
Gorton Locomotive Works, known locally as Gorton Tank, was in West Gorton in Manchester, England and was completed in 1848 by the Sheffield, Ashton-under-Lyne and Manchester Railway.
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 Western Australian Government Railways operated many unique steam, diesel and electric locomotive classes. Often suffering from lack of available funds the WAGR locomotive fleet often consisted of locomotives far older than their expected operational life. Only one electric locomotive was operated by the government during the WAGR years.
The Victorian Railways M class were 4-4-0T (tank) steam locomotives for suburban passenger service in Melbourne, a pattern engine being supplied in 1879 by Beyer, Peacock & Company. Twenty-one further locomotives of this model were built by the Phoenix Foundry of Ballarat, in three batches, from 1884 to 1886. They were numbered 40, 210-240, and 312-320, and were classed M in 1886.
The Daniel Gooch standard gauge locomotives comprise several classes of locomotives designed by Daniel Gooch, Superintendent of Locomotive Engines for the Great Western Railway (GWR) from 1837 to 1864.
The South African Railways Class D 2-6-4T of 1898 was a steam locomotive from the pre-Union era in Transvaal.
Welshpool and Llanfair Light Railway No. 1 The Earl and No. 2 Countess are narrow gauge steam locomotives. They were built by Beyer Peacock & Co. Ltd. at the Gorton Foundry, Manchester in 1902. They were delivered new to the Welshpool and Llanfair Light Railway in 1902, as No.1 The Earl and No.2 The Countess, where they continue to run today.
