Well, I got 100%, just as well....Nice work M636C.
However, the question about GM1's delivery...
I don't think there were any broad gauge power bogies at the time of GM1's delivery.
My recollection is that it was hauled from Albury to Port Pirie on spare VR S class tender bogies.
It did work a train to Albury, of course.
Not many advantages to being old.Not that I expect anyone to believe me but I got 100%.That's because you were there when much of it happened, as I was....
Thanks again Spletsie for another interesting quiz.
