The New South Wales 40 class were one of the first mainline diesel electric locomotives to be built for New South Wales. Built by the Montreal Locomotive Works of Montreal, Quebec, Canada, they were based on the ALCO RSC-3 design.[1]
There were subtle deviations from the standard RSC-3 built by the American Locomotive Company. These included a cab that angled inwards below the cab windows to reduce the width of the locomotive at the eaves of the cab roof, and placement of the handrails on the car body rather than the standard walkway arrangement.
The last unit in service was 4015, it being withdrawn on 12 December, 1971[2]. Some locomotives of this class had parts recycled in to the new build 442 class locomotives.
The lead unit of the class, the 4001 has been preserved in the New South Wales Rail Transport Museum, Thirlmere, New South Wales. 4001 returned to Service in September 2010. It is the only operating RSC-3 in the world.[3]
Two locomotives, 4002 and 4006 were sold to Robe River Mining, and modified to a Bo-Bo configuration by removing the centre idler axle from each truck. Both have been preserved, with 4002 converted back to an A1A-A1A.
The 40 class was produced in HO scale ready to run by Eureka Models. Due to be released in 2011
