By procuring a new build of tram-train car built specifically for the
operation, thus presumably built to meet the required standards. The
existing 'supertrams' will not run on heavy rail lines.

Also, I think I read that while the vehicles are dual voltage capable,
the current project doesn't require this - the heavy rail line is being
electrified at 750v DC. In the future that line may be converted to the
'national rail' standard of 25kv.

In Australia - any urban area dense enough to support a fixed rail
connection is dense enough to electrify and use heavy rail
rolling-stock. Newcastle might have application for the concept, but not
Sydney.
