The Queensland Railways 6D16 class locomotive was a class of 4-6-2T (later 4-6-4T) steam locomotives operated by the Queensland Railways.

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.

Queensland Rail railway operator in Queensland, Australia

Queensland Rail, also known as QR, is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates suburban and long-distance passenger services, as well as owning and maintaining approximately 6,600 kilometres of track.

History

Between May 1901 and July 1902, Walkers Limited delivered 20 locomotives to the Queensland Railways. Per Queensland Railway's classification system they were designated the 6D16 class, the 6 representing the number of driving wheels, the D that it was a tank locomotive and the 16 the cylinder diameter in inches. The 6 prefix was later dropped, when the remaining non six-wheel tanks were withdrawn. [1] [2]

Walkers Limited Australian locomotive manufacturer

Walkers Limited was an Australian engineering company, based in Maryborough, Queensland. It built ships and railway locomotives. The Walkers factory still produces railway locomotives and rolling stock as part of Downer Rail.

Tank locomotive steam locomotive which carries its fuel and water onboard

A tank locomotive or tank engine is a steam locomotive that carries its water in one or more on-board water tanks, instead of a more traditional tender. A tank engine may also have a bunker to hold fuel. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for shunting and shorter distance main line duties. Tank locomotives have advantages and disadvantages compared to traditional tender locomotives.

Cylinder (engine) central working part of a reciprocating engine or pump, the space in which a piston travels, often equipped with a cylinder liner

A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work. Cylinders may be sleeved or sleeveless. A sleeveless engine may also be referred to as a "parent-bore engine".

They were built to the 4-6-2T wheel arrangement. However the combination of double front bogie and single rear truck caused derailments and in 1904/05 all were rebuilt with a four-wheel swinging bolster bogie at both the front and rear thus becoming 4-6-4Ts. Between 1912 and 1918, all were fitted with new round top boilers and larger bunkers. [1] [2]

They were mainly used on suburban passenger services in Brisbane, principally between Ipswich and Sandgate although they did operate on occasions to Kingston and Lota. [1] [2]

Brisbane capital city of Queensland, Australia

Brisbane is the capital of and the most populated city in the Australian state of Queensland, and the third most populous city in Australia. Brisbane's metropolitan area has a population of approximately 2.5 million, and the South East Queensland metropolitan region, centred on Brisbane, encompasses a population of more than 3.6 million.

Shorncliffe railway station is the terminus station of the Shorncliffe line in Queensland, Australia. It serves the Brisbane suburb of Shorncliffe.

In July 1935, 375 was married to a tender from a B15 class and reclassified as a B16D class. It was followed by 376 in July 1939. Both were deployed on freight services within Brisbane. Twelve were written off in 1942/43 with the remaining eight following in 1950/51. [1] [2]

The Queensland Railways B15 class locomotive was a class of 4-6-0 steam locomotives operated by the Queensland Railways.

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.

The UIC classification of locomotive axle arrangements, sometimes known as German classification or German system, describes the wheel arrangement of locomotives, multiple units and trams. It is set out in the International Union of Railways (UIC) "Leaflet 650 – Standard designation of axle arrangement on locomotives and multiple-unit sets". It is used in much of the world. The United Kingdom uses the Whyte notation. The United States uses the simplified AAR wheel arrangement for modern locomotives.

4-4-0 locomotive wheel arrangement

4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles, four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.

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.

2-8-4 locomotive wheel arrangement

Under the Whyte notation, a 2-8-4 is a steam locomotive that has one unpowered leading axle, usually in a leading truck, followed by four powered and coupled driving axles, and two unpowered trailing axles, usually mounted in a bogie. This locomotive type is most often referred to as a Berkshire, though the Chesapeake and Ohio Railway used the name Kanawha for their 2-8-4s. In Europe, this wheel arrangement was mostly seen in mainline passenger express locomotives and, in certain countries, in tank locomotives.

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.

4-4-4 locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 4-4-4 represents the wheel arrangement of four leading wheels on two axles, four powered and coupled driving wheels on two axles, and four trailing wheels on two axles. In the United States, this arrangement was named the Reading type, since the Philadelphia and Reading Railroad was the first to use it. In Canada, this type is known as the Jubilee.

The Great Western Railway (GWR) Bogie Class 4-4-0ST were broad gauge steam locomotives for passenger train work. The first two locomotives of this class were introduced into service in August/September 1849, with the remainder following between June 1854 and March 1855. All but one were withdrawn between October 1871 and 1873, with the final locomotive being withdrawn in December 1880.

0-6-4 locmotive wheel arrangement

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.

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.
