What is the High Speed Rail passenger transport called in your country?

Australia. VFT. Very Fast Train
not yet in service

In the US, I think it is just called fantasy. It will probably just be called High Speed Rail, but the economics aren't looking too good.

I'll just leave this here

In Korea its called KTX
In Italy its called Fleschia Rossa (reds arrows) and the new comer will be called "Italo"

In Spain it is AVE (alta velocidad ?)
In Germany it is ICE (1, 2 or 3 depending on the generation)
All these terms are mostly commercial names owned by the railway companies, since they are mostly government owned (or used to not so long ago) there is a confusion between the High speed rail and the commercial name of the train: i.e. in France any HS train in any country is called a TGV when it's actually the SNCF comercial name.
