As flawed as NJT's ARC was, it at least did provide its own terminal (part of the flaws, I suppose). The one thing LIRR ESA has going for it is that it has its own terminal as well, even if it is part of the old Madison Yard. And it's still part of GCT for that reason. Remember, ESA was originally envisioned as a separate terminal east of Lexington Ave. around the original tunnel portal around 60th St. I want to say it was going to be around 1st Avenue at the bottom of Yorkville.
Penn South could be the additional capacity WoH needs, and let's remember that capacity strains should ease after ESA opens. Of course, MNRR Penn Access, Amtrak, NJT will have something to say about any capacity created.
Nah, my idea for TZB was always Cross-Westchester corridor. Transfers would have been incidental, not the main benefit.
