I couldn't imagine that neither Japan's company nor Korea's one participated in the selection of train operators.
Surely, it won't be benefit to build high speed rail between 3 cities, all of which have already been connected by frequent air service and multi-lanes highways. And, furthermore, we can't take it for granted that there would be economic growth in the area.
This is the biggest difference between American High Speed Rail and Asian one.
One of the 5 operators can deprive conventional transportations of their passengers?
I'm looking forward to seeing it.
