LOL, I thought the TGV was fast enough.
Spose it would make sense if they did sell the thing to other countries.
Those European countries like France are pretty small so I don't think super
fast trains are necessary for those countries.
Besides most services except for Eurostar and a few international services
stick to their own countries as far as I know.
ICE does Germany
Thalais does Belgium
TGV does France and so on.
A superfast train may be better suited to a much larger country or rail trip
if there is enough patronige for it to be viable.
