The X200 class were a class of rail tractors introduced in 1963 and operated by the New South Wales Government Railways of Australia. They were a development of the smaller and less numerous X100 class. The X200 class remained in service until 1990 when they were either withdrawn or sold off to private companies, and some remain operational today.

Mark 1 series

The Mark 1 series of the X200 class were 3 times more powerful and twice as heavy as the X100 class. Six examples were built and numbered X201-X206.

They were built using a number of steam locomotive spare parts. They were built on the inner bogies of the AD60 Beyer-Garratt class locomotives, and used spare C36 class locomotive windows in their cabs. Their engines were rated at 260 hp (190 kW) at 2,100 rpm and had a top speed of 24 mph. The rounded shapes of the hoods and cab gave it a baby-brother appearance to the main line 42 and 44 classes. The addition of a train brake allowed them to be run on the main line and also to be used as replacements for various ageing shunting locomotives. X201 was the first of the class entering service in December 1963. The six Mark 1s were initially used in the Sydney metropolitan network, but did later find their ways beyond this region. [1]

Mark 2 series

The Mark 2 series of the X200 class were different again. Twelve examples were built and numbered X207-X218.

They were built on the outer bogies of the AD60 Beyer-Garratt class locomotives. Their engines were more powerful rated at 290 hp (220 kW) at 2,100 rpm and they had a higher top speed of 32 mph. This made them more practical for light line use. One was even rostered on to the Yass Tramway, previously the domain of the Z13 class tank locomotives. The Z13 class were called back to Yass during periods after the X-200 failed due to transmission faults. The exterior design of the Mark 2 was squarer, giving it the appearance of a baby-brother to the 49 class diesel locomotives.

The first six were built in 1967. The second six being an additional order, were placed into traffic from May 1968, with the final member of the class entering service in December 1968. Despite differences in engine horsepower ratings, both variants were rated as having a tractive effort of 17,750  lbf (79.0  kN ). This was more powerful than many of the typical small and workshop steam shunting locomotives of the time. [1]

Summary

The X200 class must be considered largely successful, as they began to replace the various ageing steam shunting locomotives in various depots of the time. They were cleaner, more efficient to run, requiring less maintenance, and also giving locomotive crews more comfortable working conditions. Another indicator of the class' success is that several examples are still operational even today, at an age of around 45 years. Unfortunately, with the volatile and ever-changing nature of rail transport companies in the modern day, it is hard to keep a 100% accurate listing of their current owners and operational areas.

There is a certain amount of confusion with the numbering in this class. The numbers specified above apply to the class when first issued to traffic. In later years a certain amount of number-swapping was carried out by workshops. The biggest confusion being X101 and X212 swapping numbers, being two completely different types of locomotive! X217 and X218 later became X117 and X118, confusing the matter further. It appears that members of the X200 class were indiscriminately re-numbered into the X100 series. Many other renumberings exist. For the purposes of research it is often easier to refer to individual locomotives by their numbers when first issued to traffic and to note any number changes in brackets as below.

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 New Zealand DA class locomotive were a class of diesel-electric mainline locomotives operated on the New Zealand railway system between 1955 and 1989.

Under the Whyte notation for the classification of steam locomotives by wheel arrangement, the 4-8-4+4-8-4 is a Garratt locomotive. The wheel arrangement is effectively two 4-8-4 locomotives operating back to back, with the boiler and cab suspended between the two engine units. Each engine unit has two pairs of leading wheels in a leading bogie, followed by four coupled pairs of driving wheels and two pairs of trailing wheels in a trailing bogie.

The railways of New South Wales, Australia, use a large variety of passenger and freight rolling stock. The first railway in Sydney was opened in 1855 between Sydney and Granville, now a suburb of Sydney but then a major agricultural centre. The railway formed the basis of the New South Wales Government Railways. Passenger and freight services were operated from the beginning. By 1880, there was a half hourly service to Homebush.

One of the clauses in the Act required that the three Colonial Government railways, the Cape Government Railways, the Natal Government Railways and the Central South African Railways, also be united under one single administration to control and administer the railways, ports and harbours of the Union. While the South African Railways (SAR) came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways required careful planning and was only implemented with effect from 1 January 1912.
