The design was based on the Electro-Motive Diesel EMD F7 locomotive and were very similar to the GM 12 class then being built by Clyde Engineering for the Commonwealth Railways.
They initially worked express passenger services including the Brisbane Limited, Intercapital Daylight and Melbourne Limited and later the Southern Aurora and Spirit of Progress.[1][2] As newer locomotives arrived they were concentrated on the Main South line operating freight services.
By April 1978 the Australian Federated Union of Enginemen placed a ban on the 42 class operating as lead engines due to cab conditions. In 1980 4201 had its cab upgraded during overhaul to overcome these issues, but with their replacement imminent it was decided not to treat the rest of the class. All were withdrawn in 1983.
Preservation
Three have been preserved. A fourth was preserved, but this has since been mostly cut up:
- 4201 was acquired by the New South Wales Rail Transport Museum.[3] It has been used extensively on charters across the state and ventured interstate to Melbourne. It retains the green and yellow livery it received for the 125th anniversary of NSW railways in 1980. As of 2014 it has been undergoing repairs at Maintrain, Auburn.
- 4203 was acquired by a caravan park and placed on display at the entrance to the park as a gate guardian. It was later sold and the body was cut into three sections; while the central section was scrapped, O'Donohughes Irish Pub in Emu Plains brought the cab and rearmost section of the body and welded them together for use as playground equipment. The bogies and fuel tank were sold to enthusiast groups for use as spare parts.
- 4204 was acquired by the Lachlan Valley Railway,[4] After being restored by apprentices at Clyde Engineering, Kelso in 1986,[5] it has been used extensively on charters across the state and on freight services by Lachlan Valley Rail Freight. As at December 2012 it was often hired to Southern Shorthaul Railroad for use on infrastructure trains in New South Wales and Victoria.
- 4206 was acquired by the Dorrigo Steam Railway & Museum.[6] After being used extensively on the Dorrigo line hauling infrastructure and stock trains from Glenreagh, it was withdrawn when the line closed and placed in open storage at Dorrigo, where it remains today as a static exhibit.
