All roads I see lead to Illinois. What a useless system.
Notice, how nothing goes north/south. Only the coasts, and East/West, and everything goes through Chicago.
‘High speed’ is such a boondoggle. I use ‘High speed’ to refer to trains slightly faster then the current system most of the time, but slower then cars.
It's called the "hub concept", the place where people change trains.
It's exactly what Delta, United and American do at Atlanta, Chicago and Dallas respectively.
