By November 1986, Australian National's ALCo 606, seen at Mile End diesel depot was the last of its class to wear the former South Australian Railways 'mustard-pot' livery. EDIT: Don't believe everything you read on the Internet - I was just looking through some more slides and have a shot of 602 in mustard-pot I took early in 1987!!
It was unsuccessfully converted to a cabless 'slug' unit by Morrison Knudsen Australia in 1994 - what a waste!
