This locomotive was built by Beyer Peacock in Manchester in 1885. The first of these locomotives was delivered in 1880 by Beyer Peacock to John Robb who was contracted to construct the first section of the Eastern Railway between Feemantle and Guildford. The Western Australia Government Railway (WAGR) acquired this early locomotive in 1881 when the construction contract was completed.
In 1885 the locomotives were grouped as class A. WAGR acquired thirteen locomotives to this design of which twelve were built by Beyer Peacock and one by Dübs and Company in Glasgow.
The A class locomotives were initially employed on main line passenger services but were later related branch line duties. Some of the engines were sold to timber mills.
This locomotive worked on the isolated Port Headland to Marble Bar line during 1944/5. Along with other members of the class the locomotive was withdrawn from service in 1955.
A year after being taken out of service the locomotive was displayed on a plinth at South Perth Zoo.
In 1969 the locomotive was transferred to the Australian Railway Historical Society (WA Division) Railway Museum at Bassendean where it became their first locomotive exhibit.
The museum is now known as The Railway Museum, Bassendean.
One other locomotive preserved was also built by Beyer Peacock.
