The X100 class is a group of diesel locomotive built and operated by the New South Wales Government Railways of Australia.

History

A need existed for a small shunting unit that could handle the requirements at the smaller junction marshalling yards, larger intermediate stops and the workshop needs. To resolve this need, the X100, and later X200 class, was designed and built entirely in the system's own workshops from the early 1960s.[1]

X100 class were two 0-4-0 centre-cab diesel-hydraulic shunting locomotives built at the NSWGR Chullora Workshops.

They entered service in 1962 as the 80-class locomotives, but were re-classified as Shunting Tractors and renumbered as X101 and X102 before being allotted to Wauchope and Coffs Harbour. Originally painted in a crimson red and cream colour scheme, they were later repainted in the standard Indian red with chrome lining.[2]

Photos dated 1977 and 1983, show X102 in an all-over chrome yellow paint scheme and working in the Sydney area. X101 was in an all-over Indian-red scheme in 1979 and working at Wauchope.[1]

X101, which was renumbered X212 in 1994, is now part of the SRA Heritage Fleet and is being restored by the Historic Electric Train Society. X102 Finished its service with the NSWGR in the Petersham Training School and is now with the Dorrigo Steam Railway and Museum. This unit is at Port Kembla, with 108 and 118.[3][4]

They were confined to yard limits due to a lack of a "train brake" and as such could not be operated in the same way as regular locomotives. This limitation, and a need for greater tractive effort, lead to the development of the larger and more power X200 class.
