  1. CDTA:


    It is believed Quill Depot meant Utica, not Nostrand on that one (that's what I went by based on what other posters did). I assumed such in my post and failed to note it.


    Assuming I was wrong, my REVISED IRT portion in Brooklyn:


    (2) and (3) terminate at Franklin Avenue, some (2) service runs to Church Avenue, some (3) service runs to President Street.


    (4) and (5) terminate at Flatbush Avenue.



    If there is insufficient terminal capacity for the (2)(5) to terminate at Flatbush, how are the (4)(5) supposed to terminate there? How in the world would the 2/3 reverse on a pair of tracks that has 30tph in each direction? How would the 2/3 terminate at Franklin?

  2. Next:


    There's a track fire at DeKalb Avenue, suspend and/or reroute the (B)(D)(N)(Q)(R).



    (B)(D) via Culver in both directions.

    (M) to Chambers St.

    (N) No trains between Canal St and Atlantic Av.

    (Q) No trains between Astoria and Prospect Park.

    (R) No trains between Whitehall St and Atlantic Av. Additional trains operate north of Whitehall St to replace the M in Queens.


    (D) Shuttle runs between 36 St and Coney Island.

  3. Loss of power along 4 Av south of 36 St. Reroute the (D)(N)(R)


    Note: 36 St itself has no power



    Assuming this is an emergency change:

    (D) via Culver, both directions between West 4 St and Coney Island. A shuttle runs between Coney Island and 9 Av.

    (N) via Brighton Local. Runs through with the Q at Coney Island (yes, the track layout allows for this).

    (R) No service between Atlantic Av and 59 St.

  4. Next:


    All northbound switches at 149th Street are set in favor of White Plains, and all southbound switches are set in favor of Lexington Avenue. Reroute the (2), (4), and (5).


    Do not put all three on the Lex express, this is over 40 TPH and will cause insane delays. It's not possible, no matter what it may seem.



    If it's impossible, then how come the MTA always does it when there's a problem on 7 Av, without the ridiculous delays you imply?

  5. Anybody else wanna go for this? Make sure to also read extremely carefully and know the regular routes the (E)(F)(M)(R) travel before having your maps ready for these reroutes.




    Here's another complicated scenario. Have track maps ready.


    Due to a power failure at 36th Street on the IND Queens Boulevard Line, the switches are stuck in the positions they were in when the outage occurred This affects all lines, as it is south and north of the station.




    Queens Boulevard Express --> 63rd Street --> 6th Avenue Local

    Queens Boulevard Express --> 53rd Street --> 8th Avenue Local

    Queens Boulevard Local --> 53rd Street --> 8th Avenue Local

    Queens Boulevard Local --> 63rd Street --> 6th Avenue Local -> 4th Avenue Local after Bridge




    6th Avenue Local --> 63rd Street --> Queens Boulevard Express

    8th Avenue Local --> 53rd Street --> Queens Boulevard Express

    8th Avenue Local --> 53rd Street --> Queens Boulevard Local

    4th Avenue Local before Bridge --> 6th Avenue Local --> 63rd Street --> Queens Boulevard Local


    Reroute the (E), (F), (M), and (R).

    This isn't very realistic, since a power outage at 36 St, Queens should not affect switches in Brooklyn. Also, how come 4 Av local trains can only run via 6 Av Local, while B and D trains can continue via 6 Av Exp (that's only one inconsistency, there are others)?


    Despite that:

    (C) Trains run express south of 59 St.

    (E) Unaffected

    (F) Unaffected

    (M) Trains run via 8 Av in both directions between 5 Av/53 St and W 4 St.

    (R) Trains run via bridge, 6 Av, and 63 St.




    Because of a fire in a control tower, no switches can be moved along the Broadway Line between Queens/Queensboro Plaza and Atlantic Av, inclusive.

  6. Next:


    Due to the apparent issues with reading scenarios...


    The switches in Homeball Alley are all set in favor of 207th Street. This means northbound and southbound. Reroute all affected trains.



    (B) Trains rerouted to 168 St.

    (D) Trains rerouted to terminate at Dyckman St. A (D) shuttle runs between 145 St and 205 St.


    The current state of the switches won't allow that.

    Yes it will - since the switches on the lower level cannot be set toward 207 St by definition, they remain functional as per the problem's conditions.



    Due to a reconstruction project, both Manhattan-bound tracks are impassable at Hoyt St (2)(3). Because this is a long-term change, the Brooklyn-bound express track has been reverse-signalled between Atlantic Av and Borough Hall.

    Reroute: (2)(3)(4)(5), provide alternative service on other lines

    Duration: 5 years

  7. Anyone knows what went on today with the (B)? I was going southbound on a congested 4 Avenue express track and I caught a northbound (B) leaving 36 Street on the express track at 5:41 pm.


    Meanwhile, on my side of the tunnel, two (R) trains managed to race past us from Pacific Street to 59 Street… no thanks to the train dispatcher and the (N) in front of us.



    The [Wally]horse will be back and kicking.



    Police investigations at Atlantic Av and/or Dekalb Av.

  8. My belief is, you use what you have at your disposal at that point. In this case, if it means sending the (C) over the Eastern Division to get to a point where people can switch back to the (A) to finish their ride, then yes, I do that and people who get confused by it simply have to learn the hard way (as I did years ago): Sometimes, changes have to be made to keep the system running in the most efficient manner possible when something like what happened along the Fulton Street branch happens. The idea is to reduce the need for shuttle buses as much as possible and keep the system running as smoothly as possible. If people get confused, it is their fault for not paying attention and not keeping up-to-date, something people in my generation were and still are expected to do at all times.


    If I were regularly riding like I had to back in the 1980s when I used to have to go all over Manhattan, I would always have full-bore alerts available and know as best possible what re-routes are taking place. That's the level I was expected to be at when I was younger and people who only look at their route and don't plan for alternate routes in case of problems simply will learn the hard way. My way rewards people who pay attention.



    What about the tourists who barely understand English? Or those NYers who can't understand the 'riufghr ewfqwp ewfiwegfoq fwebyufgew' that constitutes an announcement in the R32s? Or those people who are not provided announcements at all?

  9. Those are some drastic police investigations:

    (A) Trains run via the (F) between Jay St and 34 St, then via the (D) to 59 St. Trains stop at 155 and 163 St.

    (C) No trains between 168 St and High St.

    (E) Two service patterns operate:

    • Jamaica Center to 34 St/Penn Station
    • Jamaica Center to 57 St/7 Av via 63 St


    (F) Trains run via 53 St in both directions.

    (J) No trains between Essex St and Kosciuszko St.

    (M) No trains between 57 St/6 Av and Central Av. Trains run via 63 St.




    The Joralemon St tunnels are impassable. Trains may use the crossover at Borough Hall and the loop at Bowling Green.

    Duration of change: 5 years. Be creative and provide as many alternatives as possible.

  10. Just curious: how difficult would it be to equip the NTTs with wireless receivers, so that every time the train passes one of any number of points it recalibrates its transfer info with that weekend's changes (programmed beforehand on a central computer somewhere)? Of course, this would be a slight expense, but IMHO it will need to be done sooner or later, as the system goes toward compete NTT-ification.

  11. Simple, everything just bypasses the station. The (S) is suspended and the (7) terminates at Grand Central


    Got one based off of what happened yesterday...


    Loss of power along the (A)(C) from Chambers St to Broadway Junction. Its the middle of rush hour and what do you do?


    Note...Broadway Junction has power and so does World Trade Center



    ---Solution A, realistic---

    (A) Trains run in two sections:

    207 St to Chambers St A/C platform and B'way Junction to Queens, both via local. Additional trains also operate between 207 St and 34 St, via express.

    (C) Suspended




    ---Solution B, creative---

    (A) Trains run in two sections:

    207 St to Chambers St A/C platform and B'way Junction to Queens, via local.

    (C) After West 4 St, trains run via the M and J to B'way Junction, nonstop. This is announced to customers as "The next stop is B'way Junction. Take this train for stations beyond B'way Junction."



    No switches can be moved between Atlantic Av/Barclays Center and Manhattan on the BMT.

  12. I never knew the IRT Livonia Avenue Line has a higher demand for Broadway/7th Avenue service than the IRT Nostrand Avenue Line. To my experience, many people got off at Utica Avenue for the (4) express if their destination is Manhattan's East Side of course. But yeah, the (3) is crowded at rush hour due to Brownsville and East New York goers.



    I said that only because there is no second service to help the (3) east of Utica Av. Hence, the more frequent service should go to New Lots, with the (5) s to Utica being rerouted to cover decreased 7 Av service along Nostrand.


    @Donald: It's a one-time change, so people will get used to it pretty quickly.
