Unknown industrial locos

Trevor Staats <steamfreak@...>

I was scanning some old pics today, and came across a pic of two yellow
0-4-0 industrial or construction locos. I have uploaded the pic to
http://www.steamfreak.com/constructionlocos.jpg - anyone have a clue as to
what they were used for and where?

The slide is dated October 1963 so possibly Snowy Mountains Scheme? Other
slides in the box include slides from Adelaide, Ballarat, various NSW towns
and Queensland.
