The G Class are a class of diesel locomotive built by Clyde Engineering, Rosewater and Somerton for V/Line between 1984 and 1989.
History By the early 1980s, the first generation diesels purchased by the Victorian Railways were nearly 30 years old, with an average fleet age of 20 years. In addition, 70% of the fleet was of 1,000 horsepower or less, a consequence of the historically large number of branch lines in the state.
Rationalisation of the rail freight task had also been carried out, with small freight consignments being consolidated to 'freight centres' from 1976. Moves had also been made towards the operation of block trains carrying a single commodity, rather than trains carrying a wider variety of freight. Grain became the major commodity carried by rail in Victoria, with the consulting arm of Canadian National commissioned by VicRail in 1983 to find ways of improving efficiency. Recommendations carried out included increasing train sizes to 50 bogie wagons and closing a number of branch lines.
Delivery At the same time Australian National had placed an order with Clyde Engineering, Rosewater for 10 BL class locomotives, with an option for a further five. VicRail's chairman Alan Reiher, stepped in and negotiated for the five to be completed for the newly formed V/Line. The new diesels had a much higher axle load than the smaller T and Y class diesels used on branch lines, with these lines either being upgraded to carry heavier trains or closed. These were all delivered in late 1984.G Class (G511-G525) RailpageG Class Vicsig
A second order was placed for ten further units that were more tailored to V/Line's requirements. The first five were built with standard gauge bogies being delivered via Sydney. Over the next few years, members of the second batch would frequently swap gauges as needs dictated. In July 1986, through running without changing locomotives at Albury began with G class locomotives operating through to Sydney."V/Line Standard Gauge Report" Railway Digest August 1986 page 247 Two further contracts for eleven and seven broad gauge units had brought the fleet up to 33 by November 1989.G Class (G526-G543) Railpage The first 15 were built at Clyde Engineering's, Rosewater factory with the balance built at Somerton.G class diesel electric locomotives Mark Bau's VR Website
Although primarily intended for hauling freight services, they were also used on passenger trains such as the Intercapital Daylight and Sydney/Melbourne Express. They rarely hauled broad gauge passenger trains."The G class locomotives of Victoria" Railway Digest April 2000 page 23
National Rail When National Rail commenced operating interstate services in the mid-1990s, seven (517–520, 522, 523 & 525) were leased by V/Line pending the delivery of the NR class."NR G Class" Railway Digest April 1996 page 37
The class were also used on the first privately operated train on government tracks in Australia, operated by SCT Logistics with V/Line locomotives and crews between Melbourne and Adelaide on 13 July 1995. This was extended through to Perth from October 2000."Freight Australia Takes Over SCT Services to Perth" Railway Digest November 2000 page 11
Freight Australia All 33 were included in the sale of V/Line Freight to Freight Victoria in March 1999. On 26 November 1999, G517 and G518 were destroyed in a head-on collision at Ararat when an eastbound grain train collided with a stationary ballast train at 70 km/h.
Freight Australia commenced a program of engine upgrades purchasing new, more powerful EMD 16-645F3B engines for some of the G class, with the old engines being used to repower X class locomotives, later recoded the XR class.Hewison, P, Kimpton, R. (2002) Freight Australia's Rollingstock Initiatives, Conference on Railway Engineering, Wollongong, 10–13 November 2002, pp. 293–294 The upgraded G classes were G523, G526, G529, G530, G531, G536, G541 and G543. These locos now have a power output of 3,800 hp (2795 kW).
In the early 2000s, Freight Australia was contracted to move freight between Melbourne and Sydney for CRT Group. The contract contained a clause that if Freight Australia was acquired by a competitor of CRT Group, of locomotive power (calculated by the business CRT Group was offering Freight Australia) was to be transferred to CRT Group. As a result, when Freight Australia was acquired by Pacific National in 2004, G516 & G534 were handed over to Linx Cargo, while 2 X class locomotives went to CRT Group, and later to Linx Cargo.
A condition imposed by the Australian Competition & Consumer Commission on Toll Holdings taking control of Pacific National was that nine locomotives be sold to SCT Logistics."SCT Logistics gains part of Toll's rail divestments" Rail Express.com.au 16 February 2007SCT secure PN starter kit Rail Express Issue 77 March 2007"SCT launches G class Kevin Sheedy Express" Railway Digest September 2007 Page 5 This resulted in nine G class passing to SCT Logistics in February 2007.
By mid 2008, SCT Logistics had received new locomotives, and their G classes were sold to the Australian Wheat Board, CFCLA and Southern Shorthaul Railroad.
Pacific National's fleet operate on both the broad and standard gauges, with the latter often operating in New South Wales.
In 2015, Freightliner purchased G533 and G535 from AWB Limited. In the same year, they passed to Genesee & Wyoming Australia when their parent company, Genesee & Wyoming purchased Freightliner and integrated their Australian operations.G&W concludes Freightliner acquisition Railway Age 27 March 2015 The 2 Gs now operate with Aurizon, following their purchase of ORA (formerly GWA) in 2022.
Qube Logistics' G521 and G532 were overhauled by Gemco and repainted in 2021.
Features The G class featured imported General Motors-Electro-Motive Division technology (prime mover, alternator and traction motors) on a locally designed frame and body. Major advances introduced with the class included cab air conditioning, onboard toilet, Trimount type high adhesion bogies, and Super Series wheel creep control to enable heavier loads to be hauled. The locomotives were designed to be of minimum mass, allowing a higher fuel load. The body consists of two side trusses with load bearing supports, roofbows and integral cabs. The side panels are made of fibreglass for the minimum weight, with various accessories mounted in removable roof hatches.
The first five units were fitted with carbody pressurisation, as fitted to many other Australian National locomotives for operation in the dusty outback areas they operated in. Differences in the subsequent units included the fitting of double blade windscreen wipers, lowering of the multiple-unit jumper receptacle, and the changing of the marker light orientation from vertical to horizontal. Recent years have seen many of the class fitted with in line refuelling, and working from Melbourne to Perth on the SCT Logistics service.

G511-515 were originally built as BL36-40. G543 was built with (and still has) a desktop cab layout, being a test bed for the DL and AN class locomotives.
