I would love for this map to come to fruition as I live right by one of the stations they have proposed upgrading to a higher speed line. However, I am not holding my breath. Building a whole new HSR line is extraordinarily expensive and time consuming, just look at CA’s ongoing project to get a taste. The density of development in the Northeast means it would probably be even more troublesome (even if it makes it more needed). If they can’t build the North-South link, then they aren’t going to build this any time soon.
