The Queensland Railways 6D16 class locomotive was a class of 4-6-2T (later 4-6-4T) steam locomotives operated by the Queensland Railways.
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 The 6 prefix was later dropped, when the remaining non six-wheel tanks were withdrawn.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]
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]
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]
Under the Whyte notation for the classification of steam locomotives, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type after a locomotive built by the Baldwin Locomotive Works in Philadelphia was shipped across the Pacific Ocean to New Zealand.
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, though the New York Central Railroad used the name Mohawk for their 4-8-2s.
4-4-0, in the Whyte notation, denotes a steam locomotive with a wheel arrangement of four leading wheels on two axles, four powered and coupled driving wheels on two axles, and no trailing wheels.
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.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 4-4-2 represents a configuration of a four-wheeled leading bogie, four powered and coupled driving wheels, and two trailing wheels supporting part of the weight of the boiler and firebox. This allows a larger firebox and boiler than the 4-4-0 configuration.
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 Twelve-wheeler.
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.
Under the Whyte notation for the classification of steam locomotives, 2-6-2 represents the wheel arrangement of two leading wheels, six coupled driving wheels and two trailing wheels. This arrangement is commonly called a Prairie.
Under the Whyte notation for the classification of steam locomotives, 0-4-2 represents the wheel arrangement with no leading wheels, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. While the first locomotives of this wheel arrangement were tender engines, the configuration was later often used for tank engines, which is noted by adding letter suffixes to the configuration, such as 0-4-2T for a conventional side-tank locomotive, 0-4-2ST for a saddle-tank locomotive, 0-4-2WT for a well-tank locomotive and 0-4-2RT for a rack-equipped tank locomotive.
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.
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 SECR K class was a type of 2-6-4 tank locomotive designed in 1914 by Richard Maunsell for express passenger duties on the South Eastern and Chatham Railway (SECR), which operated between London and south-east England. The Southern Railway (SR) K1 class was a three-cylinder variant of the K class, designed in 1925 to suit a narrower loading gauge. They were among the first non-Great Western Railway (GWR) types to use and improve upon the basic design principles of power and standardisation established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward. The locomotives were based on the GWR 4300 class, improved by the Midland Railway's ideals of simplicity and ease of maintenance.
The Prussian T 9 was a class of German steam locomotive which included several types of tank engine, all with six coupled wheels and two carrying wheels operated by the Prussian state railways.
The South African Railways Class H 4-10-2T, introduced in 1899, was a steam locomotive from the pre-Union era in the Colony of Natal.
The Queensland Railways Beyer-Garratt class locomotive was a class of 4-8-2+2-8-4 steam locomotives operated by the Queensland Railways.
The Queensland Railways D17 class locomotive was a class of 4-6-4T steam locomotives operated by the Queensland Railways.
The Natal Government Railways 4-6-2TT Havelock of 1888 was a South African steam locomotive from the pre-Union era in the Natal Colony.
The Queensland Railways 4D9 class locomotive was a class of 2-4-2T steam locomotives operated by the Queensland Railways.
The Queensland Railways 6D13 class locomotive was a class of 0-6-2T steam locomotives operated by the Queensland Railways.
The Queensland Railways 8D15 class locomotive was a class of 2-8-2T steam locomotives operated by the Queensland Railways.
