"But what does it matter what part, it will be impossible to fix as its part of an existing tunnel"
You are right about not being able to go under the East River, so that would be out of the question without another tunnel. I was just wondering how much of the project had that restriction.
I was more interested as to whether LIRR & NJT could share the ESA station space at GCT? IF the TBMs are still at the end of the ESA trailing tracks south of GCT, could they continue turning west to go under the Hudson River to replace the now dead ARC/The Tunnel project AND have a connection to WSY for LIRR?
Also, is there an online source for rail car heights? Usually I find lenghts and widths, but not always heights, even at the manufacture's sites. I usually find the info on this site (usually from your posts for some strange reason
), but have to read thru soooo many posts.
