NX Express

Honestly, such single track shuttles cause more problems than they solve. Instead of closing the subway line outright, providing only one train will cause unsafe overcrowding at the platform. In addition, an issue is that the shuttle doesn't go anywhere useful...

Why not this? Local in Queens (obviously) Local in Queens (obviously) No trains north of Queens Plaza (trains use middle track north of there) No trains north of Queens Plaza (trains use crossover west of there) Does anyone have a new scenario?

There's actually a MUCH better solution, although it involves a bit more creativity. And every hour? Seriously? I don't know buses, so I'll just deal with subways. To avoid overcrowding, there are no trains between Hunters Point Av and Flushing - Main St. Trains run as connections to the LIRR extra service. Limited service. No trains north of Queens Plaza. The following service pattern in effect: ......Trains operate at 25 trains per hour during the rush. ......Trains operate in the peak direction only in Queens during the rush hour: .........AM rush, northbound trains terminate at 145 St. They then proceed southbound to Coney Island as ( or trains and wait in the yard. .........Middays, trains run in both directions at 7 tph. In Queens, the switch arrangement allows for this, if Manhattan-bound trains wrong rail between 71 Av and Roosevelt Av. Additional trains operate between Queens Plaza and Coney Island. .........PM rush, southbound trains originate at 145 St, after having arrived there as ( or trains. No trains between Myrtle Av and 71 / Continental. No trains between Northern Bl and 71 / Continental. LIRR Lots of extra service between Jamaica and Long Island City, and between Flushing and Long Island City. NEXT Queens Blvd Express tracks closed. Provide as much alternative service as possible.

Note that the linked map says that the stops at 7 Av.

NEXT No trains can pass or stop at 7 Av/53 St. Both local tracks are blocked at 42 St - Bryant Pk. How would you reroute service? Try to minimize switching at W4 St.

Does anyone know how long it usually takes to fix something like this?

Judging by the range of explanations for the issue at Prospect Park (at various times, the reason was a signal problem, a stalled train in BIE, a rail condition, and a general mechanical problem), I'm assuming that a signal went up under a train. What is odd is that the announcements at about 5:00 PM at Atlantic Av (even on the platform) blamed a stalled Manhattan-bound train at Prospect Park. The odd thing is that that was at 7 in the morning.

And no extra service will be provided?

Do you seriously think shuttle buses would be adequate for that line? Buses were barely enough in Inwood when 181 St collapsed, and that's only because the was right nearby.

I try to keep mine to one or two station/area closures. ANYWAY... in this one I'll try to refrain from using a ridiculous number of single-track shuttles to provide service to out-of-the-way stations. No trains between 215 St and 242 St. No trains between 149 St - Grand Concourse and Borough Hall. Trains skip Hoyt St. No trains between Wall St and Borough Hall.

NEXT The 125 St Viaduct is discovered to have a structural defect. As a result, trains cannot pass or stop at 125 St. Change service and provide enough extra service on nearby lines to accommodate passengers.

I don't know what you mean by near, but I'll try. Extended to New Lots Av via the . Runs local between 42 St and Chambers St. No trains between 14 St and New Lots Av. No trains south of Delancey - Essex. ( Service suspended Trains run via the between 34 St and Coney Island. Shuttles operate from Coney Island to Atlantic - Pacific.

Grand St - closed and impassable. Provide as much alternate service as possible. Be realistic.

® trains have already used that connection many times in the past. Nothing new. If you want, you could of course stand at 57 St and wait for the first train that says 'This is a Queens bound Q train via the F line'.

Issue at Church Av appears to have been cleared.

Let's hope this is fixed by tomorrow morning...:eek:

Why? And nothing else is affected? No trains between Queensboro Plaza and Times Square. Trains run local in Manhattan and via Whitehall. Free transfer available between Queensboro Plaza and Queens Plaza during this time. No trains between Astoria-Ditmars and Times Square. Trains run via the from Pacific St to 47/50 St, then via the to 36 St (Queens). NEXT A train has broken down switching from the local to the express tracks at 34 St & 6 Av. As a result, no uptown trains can run via 6 Av. What would you do? Remember to provide equal-tph alternatives. No shuttle buses, single tracking, etc.

The can't get to/from the Lex Local except by going through the tunnels (both under the Harlem and East Rivers). And you expect the to provide enough alternative service for the , which is around 40 tph? (The already operates as frequently as it can during the rush). @Williamsburg Bridge: No trains between Delancey/Essex and Marcy Av. No trains between Delancey/Essex and Myrtle Av. All trips run as J. Service increased between Chambers St and Euclid Av. NEXT 33 St is impassable on the Lex Local - the expresses can still run. As you can't run the all via express, you must reroute something and provide equal-tph alternatives.

Why not this? I know this may sound a bit foamy, but it cuts down on switching as much as possible and keeps all lines with the same tph, whether it's the same service or not. Also, switches stay fixed pretty much everywhere. ( Runs via the from 59 St to West 4 St, then via the to Stillwell Av. Runs via the from West 4 St to Metropolitan Av. This reduces congestion at West 4 St Junction. Runs via the from 59 St to West 4 St, then via the to Stillwell Av. Both trains run via 63 St and 6 Av Express, then over the Manhattan Bridge. The E then replaces the N/Q in Brooklyn, and the F replaces the B/D in Brooklyn. Extended to Bay Ridge / 95 St. Runs via the from West 4 St to Euclid Av. This reduces congestion at West 4 St Junction. No trains between 34 St - Herald Sq and Stillwell Av. Use the E in Brooklyn - transfer at 34 St / Herald Sq. No trains running. Use the E in Brooklyn and the N in Queens - transfer at 34 St / Herald Sq. Runs via 53 St and 6 Av Local to World Trade Center. This reduces congestion at West 4 St Junction. Skip-stop suspended, runs as J. To summarize: 53 St 60 St 63 St, 6 Av Exp, Man Bridge, BMT South 8 Av Lcl ( Williamsburg Line Cranberry Tube @ CPW Problem A No trains between 125 St and 34 St - Penn Station. Very limited service runs to 59 St. Trains run local north of 145 St. B No trains between 145 St and 57 St (alternate trains run to 6 or 7 Avs). Trains relay via 63rd. C No trains between Chambers St and 168 St. D No trains between 125 St and 59 St. NEXT 28 St is impassable on the 1/2/3 line. Challenge: For each train per hour you leave in two sections, provide an equal number of extra trains per hour on a nearby line. Make sure passengers can easily transfer between the two lines somewhere. PS Avoid 2 via Lex as the East Side is over capacity as it is.

No trains between 59 St - Columbus Circle and Queens. ( No trains between Bedford Park Blvd and 42 St - Bryant Pk. No trains between 168 St and Chambers St. No trains between 59 St - Columbus Circle and 42 St - Bryant Park. Trains extended from World Trade Center to Queens to replace the . Trains run local north of 59 St. Downtown trains run local from 96 to 42 St. Uptown trains run local from 42 to 72 St. NEXT 23 St and 7 Av / 53 St ( are impassable.

Do you have a scenario to post?

I'd tweak that a bit: Trains run local between 59 St and West 4 St, then via the to Jay St. ( Trains run 24/7 and run local in Brooklyn. No trains between Chambers St and 168 St. Regular service. No trains between 34 St - Penn Sta [express platform] and World Trade Ctr. Normal service. Trains run between Metropolitan Av and Coney Island via Sea Beach. No trains from 34 St - Herald Sq to Whitehall St. Trains run every 15 minutes south of Whitehall St. Trains run every 15 minutes between Brighton Beach and Whitehall St. Trains run via the from 36 St (Queens) to 47/50 Sts, then via the to Atlantic/Pacific.

Yes, both levels of Canal , as well as Canal .

And how would the fit on one track?

My solution was similar: Regular service. ( Runs via the from West 4 St to Coney Island - Stillwell. Transfer at B'way-Laf for Brighton service. Runs express from 145 St to Canal St. Runs via the from 145 St to West 4 St, then via the to Stillwell Av. Other trains run between West 4 St and Stillwell Av via normal route. Selected trains run express from 34 St - Penn Sta to Canal St. No trains between Times Sq - 42 St and Stillwell Av. Transfer at 42 St for the ( to Brooklyn. Trains run via 63 St, bypass 49 St (no matter on which track), and switch south of 57 St. Runs via the from 5 Av - 53 St to West 4 St. No trains between Lex Av / 60 St and West 4 St. No trains between Astoria - Ditmars Bl and West 4 St. No trains between 47/50 Sts and Whitehall St. Trains run via 63 St, switching south of 57 St. NEXT Canal St on the 8 Av and B'way Lines is closed. No trains may pass or stop.

I'll try saying this reasonably. Again. You can't take three full avenues and fit the same traffic into two. Example: you can't fit 90 tph onto two tracks (but you can fit that on three).

I think you got a bit mixed up here. The 6 Av station at 34 St is also closed. After all, it's also called 34 St - Herald Sq...:tup:
