Okay, start chewing...Well a 60 class would not be in the race with any of those high speed locos but the Garret could do a good turn of speed, in 1971 I was working the southbound flyer when the compressor on 3807 decided to stop just coming into Fassifern, control in their wisdom gave us 6019 to get us moving, it was the fastest I have ever gone up Hawkmount and while not as quick on the downhill stretches to Gosford even with the engine change we were only 28 minutes behind the table at Gosford. There is no doubt even a sick 60 class would outpull any of their English racing machines.
There were claims of the ton before 'City of Truro.' 'Flying Scotsman' is shown to have reached 100 m.p.h. but analysis of the records shows a lower speed, closer to 98 m.p.h. 'Papyrus' with its recorded 108 m.p.h. is teh first undisputed ton cracking steam locomotive.
Of course, every single one of us have to be thankful for the claims put forward for 999, 3440 and 4472 because they form the basis of the decisions to keep them.
More to the point it will take a large measure of interest by enthusiasts to get more government support for the preservation of this historic loco and unless that support is evident to some degree in cash then the chances of government support are pretty thin and the loco could well end up joining the Dorrigo scrap collection never to run again.
Most steam locos were designed for a specfic purpose, so its really futile to compare them. The "City of Truro", "Flying Scotsman" and "Mallard" were/are passenger express engines, designed for power at high speed and were used mostly on lines with moderate grades. The NSW 60 class are are light line (there axle load allows them to be used on 60 lb rail) for non perishable freight, were pulling ability at relatively low speeds was the most important points. The Mallard could never pull a 1000ton grain train, but the 60 class also could never pull a 100mph express pass.
As has already been said the special claims for these machines has led them to be some of the few to be preserved, this we should all be thankfull for. One hopes 6029 will find as good a home as the already mentioned machines, no matter where this home may be.
