HSR: Chicago to New York
"The proposed NYP & CRR would have been a truly high-speed railroad with grades of less than two-tenths of one percent and curvature of less than two degrees. The mileage of the existing route between New York and Chicago would be reduced from 924 miles to 780.
The mileage of the existing route between New York and Pittsburgh would be reduced from 444 miles to 355 miles. This reduction was achieved by eliminating direct service to Philadelphia and by straightening the railroad through central Pennsylvania.Even with maximum speed of only 110 mph, travel time from New York to Chicago could be reduced from the existing 19 hours to less than 12 hours, and the time between New York and Pittsburgh could be reduced from 9 hours to less than 5 hours."
