This surprises me.

I thought that the line past North Geelong had been upgraded with concrete
sleepers.

This begs a question. Leaving aside regulations and simply looking at the
capacity of the existing line to carry a train at speed. What express
timings would be possible with a tilt train eg a Talgo or a Pendolino? This
would save a little bit of time in the Adelaide Hills

850 km/8 hours = around 106 km/hour average. Surely the line would in places
permit 130 kmh running if not 160kmh.

Turning to the technology of the line itself, what would need to be done to
upgrade it for 160 km/hr running? Is it signalling, heavier rail, what is
the principal limiting factor and are there some less costly solutions that
would lead to increased speeds?

cheers Peter
