South Australian Railways I class (second)

The South Australian Railways (SAR) I class (second) was a class of broad gauge (5 ft 3 in) 4-4-0 steam locomotives. These locomotives were a development of earlier I class designs and were primarily used for mixed traffic duties, including passenger and goods services on the South Australian Railways network. They operated across various lines throughout the state, contributing significantly to the transportation of goods and people during their service life. The 'second' designation distinguishes them from earlier locomotives bearing the same class letter. Details regarding specific modifications and service lives may vary depending on the source.
