HistoryThe 40 class were the first mainline diesel electric locomotives to be built for the New South Wales Government Railways. Built by the Montreal Locomotive Works in 1951/52, they were based on the ALCO RSC-3 design.[1][2] 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. They were originally used on heavy freight services from Sydney to Broadmeadow and later on North Coast services to Brisbane and Main South line services to Albury.[3][4] All were delivered in grey undercoat and painted in verdant green at Eveleigh Carriage Workshops. For the 1954 Royal Tour of Queen Elizabeth II 4001 and 4002 were repainted blue. In the 1960s all were repainted Indian red. With major electrical work required and their lack of power compared to other diesels, the 40 class were withdrawn from May 1968 with the last being taken out of service in December 1971.[5] Some had parts recycled in to the new build 442 class locomotives. PreservationThe NSW Rail Museum preserved 4001. It was returned to traffic in October 2010 painted in the blue livery it received in 1954 to haul the Royal Train.[6] Robe River Iron Associates purchased 4002 and 4006 for use on construction trains and later as shunters in the Pilbara region of Western Australia where they were renumbered 9405 and 9401. These were withdrawn in 1979 with 4002 donated to the Pilbara Railways Historical Society and returned to working order while 4006 was donated to the Wickham Lions Club and placed on a plinth at the tourist information bay.[3][7][8] ModelingThe 40 class was produced in HO scale as two different runs of brass models by David Anderson. They are produced as ready to run by Eureka Models. It was released in late 2017. A representation of the 40 class has previous been made by modifying an Atlas RSD-4/5 model both in HO and later in O scale, primarily by replacing the cab and making several detail changes, though retaining the incorrect unequal axle spacing of the Co type bogie instead of the correct A1A type. {{-}}References1. ^{{cite magazine|title=40-Class Diesel-Electric Locomotive|magazine=Australian Railway Historical Society Bulletin|date=April–May 1952|pages=37–38; 54–55}} 2. ^40 class Vicsig 3. ^1 {{cite book|last=Oberg|first=Leon|title=Diesel Locomotives of Australia|year=1980|publisher=AH & AW Reid|location=Sydney|isbn=0 589 50211 5|pages=9, 73}} 4. ^40 Class Railpage 5. ^{{cite magazine|title=The 40-class Diesel-Electric Locomotives of New South Wales|last=Preston|first=Ron|magazine=Australian Railway Historical Society Bulletin|date=January 1972|pages=8–21}} 6. ^(A Leaver, September 2010 Roundhouse) 7. ^Exhibits Pilbara Railways Historical Society 8. ^Railway Digest February 2012 Further reading
