Isn't it also the case that a lot of the current NEC alignment is never going to be Class 9 (thinking the Shore Line in CT). Without realignment of the route true HSR is just not possible.The track would have to be FRA class 9 to be above 160.
Amtrak is going to maintain it only to Class 8 (160) and Avelia itself needs to solve its pantograph/catenary bounce problem to be rated a solid 165.
I’m pretty sure F-Line has already answered both the Class 9 question and how a lot of Acela travel time reductions comes from notching up its operations in the 90 to 125 range to the next level
