History

Numbered 38 and 44, numbers vacated by two withdrawn Geelong and Melbourne Railway Company engines. Classed 'G' in 1886.^[2]

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.^[2]

Regular service

Based at Castlemaine in the 1890s presumably for the Maldon line.^[2]

Design improvements

Both reboilering in 1882. No.38 fitted with an extended smokebox.^[2]

Withdrawal

Both the locomotives were scrapped in 1904.^[2]
