Australian GM class locomotives

 

In Commonwealth Railways service, no. 27 is seen with the Indian Pacific (see earlier posts) near Broken Hill in the 1970s.  Later Commonwealth Railways became Australian National.  A total 47 of these standard gauge units were built in different batches from 1951 to 1967 by Clyde Engineering whose design was based on the General Motors EMD F7 locomotive.  The first 11 had an A1A-A1A axle arrangement, the rest a Co-Co axle arrangement.  Power output of the first 11 was 1500 hp (1119 kW), the rest 1750 hp (1305 kW).   Apparently this unit, along with 3 others, is still used by the Southern Shorthaul Railroad.
