And other cities connected.
St. Louis to Chicago with two right-angle turns in 80 minutes?
Overmod St. Louis to Chicago with two right-angle turns in 80 minutes?
Chicago to Springpatch, 80 minutes, one 90 degree change of direction, could be a wide curve out in cornfields.
Chicago to St. Louis, 120 minutes, two big turns, according to the text.
Remember that even a 12-mile-radius curve is limiting at these speeds (see the discussion of 'second spine' routes through Hartford)
Second curve means new route has to be west of the IC or very long crossover structure with long vertical curves would be needed.
Springheel needs to be in this HSR exactly as much as Maaaadison does for Milwaukee to the Twin Cities.
These HSR plans seem to be hatched at the large state universities. This one dog-legs thru Champaign, Wisconsin's ended at Madison, Michigan's route Detroit-Grand Rapids takes a jog thru Ann Arbor, and Ohio's ends at Columbus.
