A view of the two main types of shunters used by the South Australian Railways to replace steam and see their successor Australian National through to the early 1990s.
Late on the afternoon of 13 April 1989, English Electric units 803 (rated @ 800hp with a 6SRKT engine) and 515 (rated @ 500hp with a 4SRKT engine) pause between duties at the Gillman marshalling yard near Port Adelaide.
803 was built by English Electric at their Rocklea works in Brisbane in 1956 and withdrawn from service in mid-1990 - I have one of its headlights in my shed.
515 was more fortunate. Built by the SAR at their Islington Workshops in 1966 it was withdrawn in 1992 and subsequently preserved at the National Railway Museum, just a couple of kilometres from where this photo was taken.
