A NY Chicago train via Pittsburgh is currently ~920 miles...if it were HSR, the run from Philly to Pittsburgh would likely be at least 40 miles shorter (the turnpike is 300 miles and Pittsburgh is 265 miles as the crow flies). at an average of 110 mph a trip from Philadelphia to Pittsburgh would be 2h45m or there abouts, 1h more for NYP. Assuming the the one hour trip will occur with improvements to the nec (acelas currently can make the run in 65 min). to get 2h45 min you'd need this
as well as some improvements to keystone east. beyond that, I think adding back capacity and increasing top speed to 110 could do a lot to create a functional corridor of NY-Philly-Lancaster-Harrisburg-Pittsburgh-Cleveland-Toledo-South Bend/Elkhart-Chicago. It might not compete with the nec but it would also cost far less. the NY-Phily-Pittsburgh section would be completely transferred with travel times from NYP cut from 9.5 hrs to 3h45m and from philly from 7h23m to 2h45m. you'd also be slashing travel times to DC and baltimore via Philadelphia.
Concept 4 - New passenger only high speed rail line between Harrisburg and Pittsburgh,http://testplant.blogspot.com/2012/05/k ... study.html
generally following the Pennsylvania Turnpike or other major transportation corridor. (Cost
$6.3B).
