The South Australian Railways P class was a class of 2-4-0T steam locomotives operated by the South Australian Railways .
History
The first six were built by Beyer, Peacock & Co for the South Australian Railways (SAR) in 1884.[ 1] [ 2] [ 3]
Their design was based on an earlier design built by Beyer Peacock for the Isle of Wight Railway . The New South Wales Government Railways F351 class locomotive was also based on this design. The class was successful and a further 14 locomotives were built by James Martin & Co .[ 2]
Initially the locomotives served hauling suburban trains in Adelaide until replaced by the F class in the early 1900s. In 1899, the SAR took over operations on the Glenelg Railway Company's two lines. The P and K classes replaced the small tank engines on this line, running until 1929 when the lines were closed. The P class served out the remainder of its career on shunting duties and hauling freight trains between Adelaide and Port Adelaide .[ 2]
P117 has been preserved by the National Railway Museum, Port Adelaide .[ 2]
