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 The X200 class remained in service until 1990 when they were either withdrawn or sold off to private companies, and some remain operational today.

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.

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.
