AN did do a trial of dual gauge train at Port Augusta. I don't know that
it got
up to any speed though. It was done on a siding.
BTW, the trial train was a passenger train made up of IP and Overland
cars.

They may have run dual gauge trains on this line. It is the only line of
any
length so fitted. However, Snowtown never had any dual gauge track. The
two
sections would had to have been joined at the convergence point.

To my knowledge there has been no dual gauge operation of Broad/Standard
and 
Narrow gauge. At least, not in this country.
