I swear people don't read these days. I thought you would learnblesson when you kept asking people for updates from other posts. If I didn't make an update then this project is held.
But since I'm here I will elaborate that it will be changed to the (7)<7><8>(9)
All trains terminate at Battery Park. The 4 yards that support these trains are:
Coney Island Yard
Bayview Avenue Yard
Battery Park Yard
Manhattan Beach Yard
The (7) is Neptune Avenue express running from Sea Gate-West 37 St to Battery Park. Late nights it runs local. Weekdays express until Fulton Street. Then regular local service with the (9).
The <8> is the Luna Park Local / Neptune Avenue Express. It starts from Stillwell Avenue with the (9). It runs express with the (7) until it diverges via the Brighton Tunnel on to Brighton Bch/Oriental Blvd. it terminates at Kingsborough Community College-Manhattan Beach. Some (7) trains terminate at Manhattan Beach.
The (9) is the Neptune Avenue Local. Also based out of Stillwell Avenue, it runs local until Fulton Street and does regular service to Battery Park. Late nights the (7) replaces the (9) in both Brooklyn and Manhattan.
This line finished completion will be 2020 in the Spring or sooner based on the Capital Budget for the NYCTBA under Dagard Rapid Transit Authority.
