The Victorian Railways G class was a class of 4-4-0 light line passenger locomotives operated by the Victorian Railways between 1877 and 1904.

History

Numbered 38 and 44, numbers vacated by two withdrawn Geelong and Melbourne Railway Company engines. Classed 'G' in 1886.

Production

Built by the Williamstown Workshops in 1877. Design was similar to the 1874 K class in both power and weight. The four-wheel bogie instead of a fixed axle at the front reduced the maximum wheel load a little and improved lateral stability. All Meikle engines had been fitted with almost standard four-wheeled tenders, differing only in minor details, but this new design had a wheelbase of 8 feet compared with 7 feet and had a larger capacity.

Regular service

Based at Castlemaine in the 1890s presumably for the Maldon line.

Design improvements

Both reboilering in 1882. No.38 fitted with an extended smokebox.

Withdrawal

Both the locomotives were scrapped in 1904.
