I realise that it is all pie in the sky now but is GM 10 still around? (Probably the next best thing to GM 1.)
Yes, GM10 is still around and in working order.
It is still in the yellow and black SSR colour scheme. It appeared at the "Streamliners" event in Goulburn.
It may have run to Port Augusta as one of the locomotives to collect the coal wagons for SSR.
I suggested GM27 because it is in the later black nose scheme similar to the CLP colours (black substituting for green).
Back in 2000, GM10 had just been painted in the Great Northern red and maroon scheme.
Even the cab interior looked like an excellent museum exhibit.
It even had reproduction builder's plates. I've liked it ever since.
It has had its mesh grilles replaced by horizontal bar grilles applied to GM12 upwards.
But it would be good to have GM10 in PA for the day, although since SSR have done so much for railfans (the C class tour, Streamliners) it seems unfair to ask them to do more simply because GSR have different priorities.
If someone had the money to spare, it could be painted in CR colours, but that isn't SSR's problem.
On another subject, the special train for the Sod Turning was only five cars. It might be possible to find five crew cars spare for the day to carry a small party from Adelaide to Port Augusta. I'm sure some politicians and press could be encouraged to attend, just to raise the profile of the occasion.
