I'm surprised, astonished!! I've never had the chance to investigate the Crookwell line though I did drive Goulburn - Orange twice 20+ years ago.
I remembered noticing these odd point levers somewhere probably on a tour in the early 70s which meant either Canberra line, ie something to do with Captains Flat, or Crookwell line. I opted for Crookwell and picked Woodhouselee as it was ~halfway along.
When were these shots taken? Do you have more online?
I'll get a new shot up tomorrow.
