South Australian Railways 0-6-4 Locomotives in Australia


Class Details by Steve Llanso of Sweat House Media

Class K (Locobase 5680)

Data from Douglas Colquhoun's entries presented in the Australian national railway museum site: [] (visited 14 October 2003).

Unusual wheel arrangement with a relatively low percentage of the total weight on the drivers for the type. The first 3 (works # 1824-6) went into service in February 1879. 37 (works 1851) followed 9 months later, and 42 (works 1936) landed 13 months after that. Three more (works 2246-48) arrived in February 1883, 3 more (2305-7) in October 1883, and the last 6 were built as a sextet (works 2530-2535) but delivered in two batches in November 1884 and February 1885.

One of Colquhoun's numbers seems out of sequence. He credits locomotive 60 with works 2124, yet it arrived considerably later than the others in June 1887.

Most were rebuilt early in their careers and all lasted until 1936 in most instances although 4 stayed in service for 20 more years.
