The South Australian Railways P class, was a class of broad gauge 2-4-0 tank engines operated by South Australian Railways.[1][2]

Motion of the South Australian Railways P Class Locomotive

The first 6 locomotives of the class were built by Beyer Peacock Beyer Peacock & Co in 1884. Their design was based on an earlier design built by Beyer Peacock for the Isle of Wight Railways. The New South Wales F351 class locomotive was also based on this design. The class was successful and a further 14 locomotives were built by James Martin & Co, a local builder.[3]

Initially the locomotives served hauling suburban trains in Adelaide until replaced by the F class in the early 1900s. In 1899, the South Australian Railways took over operations on the Glenelg Railway Company's two lines. The P class and K class replaced the small tank engines on this line, running until 1929 when the lies were closed. The P class served out the remainder of its career on shunting duties and hauling freight trains between Adelaide and Port Adelaide.[4]

One P class locomotive, P117, survived scrapping. It is now on display at the Port Dock Railway Museum. [5]
