The V/Line G class mainline diesel electric locomotives built by Clyde Engineering from 1984, the last entering service in December 1989.[1] They were newest and most powerful locomotives in the Victorian broad gauge freight fleet until the XR class entered service, and can be considered a more technically advanced version of the C class.[1] The class can be grouped into 4 subgroups, locos in the initial subgroup derived from the BL class locomotives, with later subgroups having minor detail changes.

Major advances introduced with the class included cab air conditioning, Trimount type high adhesion bogies, and Super Series wheel creep control to enable heavier loads to be hauled.[1] On delivery to V/Line the class enabled the retirement of many lower horsepower locomotives, such as the B and S classes. They initially saw use on the mainlines, due to their heavier axle loading. Duties included intercapital freights, grain haulage, and Melbourne to Sydney passenger work.

Today track upgrading and branch line closures has seen the class usable on the majority of the Victorian network. Recent years have seen the class fitted with on line refuelling, and working from Melbourne to Perth on the Specialised Container Transport (SCT) service. After the sale of V/Line Freight, the new private owner Freight Australia rebuilt a number of G class locomotives with higher horsepower engines, cascading engines to the X class.

Two G class locos were accident damaged and were replaced with the V class locomotive V544. Another 2 members were transferred to Colin Rees Transport (now a part of QRNational) when Freight Australia was sold to to Pacific National,[2] as are 9 locomotives now with Specialised Container Transport due to an Australian Competition and Consumer Commission (ACCC) decision on the same sale.[3] The majority of the Pacific National owned fleet is on SG (like the rest) whist only 3 are on BG.
