I prefer photos of the archaeology when it was in full flight.

Is spot on with Teralba.
Crisfitz, re Mortlake line, I'm a bit surprised you didn't spot the much-weathered platform mounds of the short-lived Koonendah/Keilambete station, but (if not perhaps bulldozed) they can be hidden if that paddock has grass at maximum height. It is really probably the flattest, most featureless branchline in Vic, but sad to hear that even the few remaining remnants are gradually disappearing.
I'm hoping to post something within the next day, I'll advise if it doesn't pan out.
