From what I was reading the axle loads on some steamers was not that light , I didn't notice their lengths but I suspect it may be more than 21-22m .The 57 class were allowed to Thirroul on the Illawarra but were not permitted on the North at all since a number of bridges were too weak (Cockle Creek, Ourimbah, Wyong, all of which were replaced in the early 1960s) but significantly because they were too wide for some tunnels.
Some of their quoted max speeds looked interesting and I think one was quoted at a little over 90 miles per hour . Hmm , 22TAL at 145 km/h with hardly modern suspension .
Bridge wise they support the total mass of the loco/s with the rails and sleepers distributing this load . Todays heavier rails and sleepers should be better than what was around 40-50 years ago .
For the steamies , what infrastructure limited the areas D57s could go ? I think it was Junee south and Lithgow west , can't remember north and Illa .
Curious to know what Saudi Arabia has to do with Australia. Other than rhyming....As Downer is withdrawing from loco assembly, we are postulating on the shape of future EMD's

The Passenger Rail Authority of South Africa (PRASA) has rebently signed a lease agreement with Swifambo for 20 Cape gauge Vossloh Espana Euro 4000, prime mover will be a 16-645 http://mainlinediesels.net/index.php?nav=1000001&lang=en&id=5491&action=shownews#.UldI4VOyl1E

Basically a GT46CU tarted up in a European shell
I do not know if PRASA locos provide HEP, if not the Euro 4000 probably has a 1000 HP too much for Cape gauge DC traction motors, may be fitted with a 12-710?
In Europe units with 12-710s are marketed as Euro 3000, and this name would be used for exports as well.I went with the Euro 4000 designation, as this was the model quoted in the press releases and on Vossloh's web site
