This first one has a 45 and a 48 in a small loco depot, taken probably in the late 1960s or early 1970s. I had thought Cooma, but it could be Armidale for all I know.
This second one really has done my head in. I would love it to be somewhere exotic like Batlow, but it could be Lithgow or somewhere out west. This latter guess is based upon the cloud formation!
Any better guesses folks?
