Another part of my childhood, as I recount here — which at the moment is Google top hit for “C32 steam”! This picture could have been taken on the Illawarra Line, though in fact is on Mount Victoria in the Blue Mountains. It is certainly the kind of regular South Coast train I saw every day through the 1950s from my vantage point in Vermont Street Sutherland. This C32 was built by Beyer Peacock & Co in the UK in 1891!
Linked to an excellent resource from which this image is taken.
