edf40wrjww2msgDetail:detailStr fiogf49gjkf0d As previously noted, my plan to do this that would would split up the (J) and (Z) into bona-fide separate lines that would meet at Chambers Street:
In this scenario, the (J) is truncated full-time to Chambers Street and terminates on the "express" tracks there since the (Z) would pick up Broad and Fulton Streets with that line 24/7, running as follows:
Weekdays (5:30 AM-11:00 PM):
New (Z) is essentially the old "Brown (R) Bankers Special," except this version would be running both ways between Chambers and 95th Street-Bay Ridge at all times. During the week, coming north the line terminates on the northbound "local" track at Chambers, then after fumigation goes past the switches on the old northbound local/bridge track. As soon as there is no traffic, such (Z) trains would cross over to the southbound "local" track for the return trip to Brooklyn.
By design, this would have a (J) train coming from the north at Chambers Street meet a (Z) train coming from the north, with the reverse true on the south end. As this new (Z) train would run with most likely a maximum of 8 trains per hour (even at peak hours) as it is designed to be a supplement to the (R) in Brooklyn and NOT replace it, during rush hours the handful of (J) trains NOT slated to meet a (Z) train at Chambers would continue to Broad Street and terminate there, then start back at Broad to Jamaica Center. All such trains (plus a few others that do run to Chambers) would have a <J> designation in skip-stop along the portion between Broadway Junction and Jamaica Center stop at stations currently served by the (Z) (while trains marked (J) would do skip-stop at stations currently served by the (J) at those times).
All other times (11:00 PM-5:30 AM weekdays AND 11:00 PM Friday-5:30 AM Monday):
New (Z) is extended to Metropolitan Avenue to absorb the current (M) shuttles during those hours, running from there to 95th Street. This also absorbs the current late-night (R) shuttle as well.
Probably the best way to at least address the Brooklyn issues as unless you were going to the NYSE or other places in lower Manhattan (and weekends and late nights parts of Willamsburg), most people would use this (Z) to where they transfer to other trains, which would be its main purpose.
This also likely allows for other services to use the Broadway-Brooklyn during the upcoming (L) shutdown, including most likely a beefed-up (M) (with as I would do it having such trains designated as "Orange (T)" running to 96th Street-2nd Avenue).
