Queensland Railways steam locomotive classification

Last updated

Between 1864 and 1958, Queensland Railways ordered 47 types of locomotives for purposes such as freight, passenger and mail train use.

Classification

Until 1889, each of the isolated sections of the Queensland Railways adopted its own locomotive numbering system. With the impending joining of most of the sections, in 1890 a new centralised classification system was adopted to eliminate duplications. Locomotives on the Southern & Western Railway retained their existing numbers, with locomotives on other networks renumbered where there was a duplication. [1] [2]

The classification system consisted of a letter, indicating the number of driving axles, followed by a number, indicating the cylinder diameter in inches and factions of inches. This was confusing for two reasons:

Where classification numbers were duplicated, the classes were usually distinguished by the name of the builder, e.g. A10 Baldwin, A10 Fairlie, A10 Neilson. [1] [2]

In the case of tank locomotives, the number of driving wheels was added as a prefix, e.g. the 6D16 class had six driving wheels. With all four wheel tank locomotives, the prefix was dropped, thus the 6D16 class became the D17 class. [1] [2]

Number of driving axlesInternational classificationQR classification
1A-
2BA
3CB
4DC
3 (Tank locomotive)D

Improved versions of a similar class were given a second identical letter. For example, the improved version of the D17 was the DD17.

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.

<span class="mw-page-title-main">0-6-6-0</span> Articulated locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, a 0-6-6-0 wheel arrangement refers to a locomotive with two engine units mounted under a rigid locomotive frame, with the front engine unit pivoting and each engine unit with six coupled driving wheels without any leading or trailing wheels. The wheel arrangement was mostly used to describe Mallet locomotive types and in some occasions, Double Fairlie locomotives.

<span class="mw-page-title-main">2-8-2+2-8-2</span> Locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-8-2+2-8-2 is an articulated locomotive using a pair of 2-8-2 power units back to back, with the boiler and cab suspended between them. The 2-8-2 wheel arrangement has a single pair of leading wheels in a leading truck, followed by four coupled pairs of driving wheels and a pair of trailing wheels in a trailing truck. Since the 2-8-2 type was known as Mikado, the corresponding Garratt and Modified Fairlie types were usually known as Double Mikado.

<span class="mw-page-title-main">0-6-0+0-6-0</span> Locomotive wheel arrangement

Under the Whyte notation for the classification of steam locomotives, 0-6-0+0-6-0 represents the wheel arrangement of an articulated locomotive with two separate swivelling engine units, each unit with no leading wheels, six powered and coupled driving wheels on three axles and no trailing wheels. The arrangement is effectively two 0-6-0 locomotives operating back-to-back and was used on Garratt, Double Fairlie, Meyer and Kitson-Meyer articulated locomotives. A similar arrangement exists for Mallet steam locomotives on which only the front engine unit swivels, but these are referred to as 0-6-6-0.
