Victorian Railways G class (1877)

The Victorian Railways G class locomotives were a class of 2-4-0 steam locomotives that operated on the Victorian Railways (VR) of Australia from 1877. Designed by William Wright, the VR's Locomotive Superintendent, they were primarily intended for mixed traffic duties, handling both passenger and goods services on branch lines and main lines. The G class was one of the earlier locomotive designs used extensively on the Victorian Railways and represented a significant step in the development of the VR's motive power.

These locomotives featured a relatively simple design compared to later VR locomotives. Their 2-4-0 wheel arrangement provided a balance of tractive effort and speed suitable for a variety of tasks. Key features included outside cylinders, Stephenson valve gear, and a characteristic Victorian Railways boiler. The locomotives were constructed by several manufacturers, including local Victorian builders and overseas firms.

The G class served for many decades, becoming a ubiquitous sight on the Victorian rail network. As heavier and more powerful locomotives were introduced, the G class locomotives were gradually relegated to lighter duties and branch line operations. Many were eventually scrapped, but a few examples have been preserved, representing an important part of Victoria's railway heritage. Their operational life spanned a significant period in the development of Victorian Railways, reflecting the evolving needs and technology of the time.
