The PATH midtown line, however, retains its current 33rd street terminal. Likewise, The 7 line on that map is shown extended down its existing tail tracks to the vicinity of Chelsea Piers, but still ends with a stub-end terminal there.
Others have suggested extending the 7 into New Jersey with a new, dedicated tunnel under the Hudson. But how about just connecting the 7 to the PATH instead? Would that be the most direct route to NJ, well, not really... but I still think it would be useful, and a 3/4 mile connector to link the 7 line on 11th Ave to the PATH line on 6th Ave would be heck of a lot cheaper than a brand new tunnel to NJ.
It absolutely is doable to fold PATH into the subway, and it is incorporated into this map I made here: https://drive.google.com/open?id=1fN...RY&usp=sharing
Essentially, you have to build a new deep tunnel coming out of PATH at West Street, then passing below the existing PATH station to a new station under Vesey Street, then following Park Row and Centre Street to the Lexington Avenue Subway. This leaves the existing PATH station empty which leads me to the description of the map as a whole:
Essentially, this map proposes making PATH, LIRR, and NJT into a regional rail system like the RER in Paris or the S-Bahn in Germany in which all suburban trains concentrate onto several trunk lines that pass through the city to the lines on the other side, at least every 15 minutes all day long. This would create essentially an express express subway for city dwellers, and allow suburbanites to pass through the city, and simplify services. Essentially what I propose can be broken down into seven parts:
Part one: Amtrak
All Amtrak trains from New Jersey will pass through the new Gateway tunnels, then out to Long Island via the southern two East River tunnels.
Part two: Regional rail line A
All regional rail lines from Newark Broad Street Station will consolidate onto a new trunk line to Hoboken (a new transfer station would be constructed in Harrison to allow transfers to other lines). At Hoboken, trains would dive into a new tunnel passing through to the PATH station at WTC, vacated by the PATH-Lex construction. A new tunnel would continue southeast to Atlantic Station, where all trains would continue through to Jamaica, and continue onto all LIRR lines entering Jamaica from the northeast.
Part three: Regional rail line B
All trains entering Secaucus Junction from the northwest will continue to Hoboken. There, they will enter the Uptown Hudson PATH tubes, and follow the line to 33rd Street Station. A short, 0.8 mile long tunnel under 34th Street and Park Avenue will connect this line to the LIRR East Side Access tunnels, which the line will follow to Jamaica, fanning out to all LIRR lines entering Jamaica from the southeast, via St. Albans. The LIRR line from Rosedale to Jamaica via Laurelton will be turned into an extension of the E train subway.
Part four: Regional Rail line C
This would consist of all trains from Newark Penn Station passing through Penn Station in Manhattan, then through the northern two East River tunnels, and onto the LIRR Port Washington Branch
Part five: Path-Lex Subway
This would consist of the Newark-WTC PATH line (the only one that would remain) connecting through to the Lexington Avenue subway as described above.
Part six: Metro North
Metro North would stay as Metro North, at least in my proposal, for the sake of realism. If it were to ever be extended, I would expect it to go to Staten Island, either via Brooklyn or Jersey City, and then maybe to the West Trenton line and/or Raritan Valley line in New Jersey.
Part seven: Hudson Bergen Light Rail.
HBLR would remain as it is, except it would pass through a new tunnel entrances in Paulus Hook and Hoboken into the abandoned PATH tunnels through Newport. This would allow trains to pass through Jersey City faster.
