The average speed is what really matters, Amtrak really needs to fix all those slow areas...

There would have to be separate lines built to be able to reach it's highest speeds for the longest period of time to not have to share it with other trains but that would mean new tracks, stations, bridges, and overpasses.

I suppose if new lines were built it could be Maglev but it wouldn't have the flexibility for the fast trains to extend into additional routes or have other trains sometimes share segments of the high speed tracks if need be.
