Path or Port Authority Trans-Hudson is a very interesting subway system, it is a subway spanding from New Jersey Areas such as Newark, Hoboken, Jersey City, Harrison and Lower Manhattan. The lines im suggesting are the Newark-WTC Line Journal Sq-33rd Street I dont personally know much about the PATH system but there are many videos articles and images out there Heres some links to it https://en.wikipedia.org/wiki/PATH_(rail_system)
I approve of this, but I would like the entire system since the blue and green are short and links up with the red and yellow lines.
I approve of this idea and if you want to combine this with the New York City subway best bet are 14th St Gives access to 1,2,3 F,M & L Trains those are connected to the PATH train system by a passageway. World Trade Center connection is available to 2,3,A,C,E & R Trains. Provided DTG wanted a Underground commuter Pack. I've been on the Yellow Line Journal Square to 34th Street Herald Square. Note but the late-night service has Yellow and Blue Lines Combined to run as Square to 34th Street Herald Square 33rd Street platforms via Hoboken terminal. Green Line Doesn't Run which leaves the red line unchanged.
