NX Express

The point of SAS is to relieve the Lexington Avenue Line. That comes from providing outer-boro residents a way to get to the East Side without the .

The Chrysler Building is nowhere near 2 Av. @Rollover the will be almost pointless as a Manhattan shuttle. It needs to go to the outer boroughs, preferably the Bronx, but more realistically Brooklyn.

Please, check a track map - these changes are quite unrealistic. http://www.nycsubway.org/maps/track.html Here's what I'd do: Trains run in two sections - Bronx to 2 Av, via the between 145 and W4 St, and West 4 St to Brooklyn. Downtown trains run express from 145 to Canal Sts. Uptown trains stop at the express track at 42 and 47/50 Sts. to Broad St. PS Here's the unusable tracks, highlighted in black:

Buses are pointless because there are so many subway lines nearby. But if it's necessary: BUS1: 2 Av - Grand St - Delancey/Essex BUS2: Canal St - City Hall - Cortlandt St - Rector St - South Ferry/Whitehall St. No trains between 34 St-Herald Sq and Whitehall St. Reduced service in Brooklyn. No trains between 2 Av and Whitehall St - take the to connect between sections. Trains run via the Manhattan Bridge in both directions. NEXT The outside tracks at 47/50 Sts are unusable. Reroute: southbound , northbound , anything else as needed

The and are running through. There are too many trains for that.

When we compare speeds, does that require you to stop at all stations? If not, it's meaningless.

What if every other ran via the to Brighton Beach (switching after Dekalb), and the was instead relocated to terminate at 9 Av (or 62 St, or Bay Pkwy...)?

Run via tunnel Selected trains run via the to 47/50 Sts, then via the to wrong-side 63 St, terminate there (now that the wall has been taken down), wrong-rail via 57 St/7 Av to the other level of 63 St, merge with the , then the , back to Brooklyn. Trains run via the line between Atlantic Av/Barclays and 47/50 Sts, then via the to 36 St, Queens. NEXT No trains can pass City Hall, or the Manhattan Bridge north side. NOTE: all outer-boro lines must have the same tph to Manhattan as before. Affected: , , , , others as needed

I think that was a mockup, not an actual picture.

Why would trains end early?

No uptown trains can pass 23 St on the Lex, 6 Av, or B'way Lines. Sorry if that was unclear.

It could theoretically work, with a relay TO, using the middle track south of 34 St. Agreed, however, it is not ideal. About the , 59 St would be better. And since the runs ~30tph, the would be too much for one track, so some trains are short-turned. No trains between 2 Av and Euclid Av. Trains run via the line between West 4 St and Jay St. No trains between Marcy Av and Broad St. No trains between 2 Av and Myrtle Av. No trains between Marcy Av and Broad St. NEXT All uptown tracks are closed east of 7 Av at 23 St. Affected:

Trains run via the line in both directions between West 4 St and Jackson Hts. Trains run between 14 St/8 Av and Metropolitan Av. Trains run via the between 149 St and Nevins St in both directions. The last stop on some southbound trains is 86 or 68 St. Other trains run express from 125 to 42 St. NEXT The following locations are impassable: 23 St The 8 Av tracks at 53 St ( only) Reroute: , and anything else as necessary

No trains between 34 St and Chambers St. Suspended Suspended 8tph run via the line between W4 St and 5 Av/53 St. Other 7 tph run via 63 St and terminate at 42 St-TSQ (Broadway), on the express tracks. No trains between Broad St and 71 Av. No trains west of 3 Av. No trains south of 34 St. Trains run via the in Manhattan. No trains south of 96 St. NEXT The two uptown tracks are impassable at 8 Av/53 St. Affected:

No trains between Jay St and Chambers St. Local in Manhattan and Brooklyn. Suspended No trains between York St and Essex St. Trains run via the tunnel to provide additional service at Jay St. Trains run local between 36 St and Atlantic Av/Barclays to provide additional service for passengers at 4 Av/9 St. NEXT 4 Av/9 St impassable. Rules: All lines (except 4 Av obviously) must have the same tph to Manhattan as before (or more).

If you look carefully, there is a way around the problem. Here's what I would do: Uptown trains run via the line from Jay St to B'way Laf. After B'way, trains switch to the express tracks (to avoid interfering w/ trains) and run via the to 59 St. No trains between Chambers St and 34 St. Uptown trains run via the line between West 4 St and 5 Av/53 St. Unaffected. No trains between Chambers St and 71 Av.

How would the fit on one track?

No trains between Borough Hall and Utica Av. The last stop on selected southbound trains is Bowling Green. Uptown trains run via 7 Av in Manhattan. The last stop on selected southbound trains is Atlantic Av. Rerouted, after Franklin Av, to Flatbush Av. NEXT Because of a smoke condition, the uptown tracks are closed at 8 Av/23 St. Reroute:

The can be a shuttle from Brighton Beach.

Is that late night or all times? If late night: No trains east of Court Sq. No trains east of 21 St-Queensbridge. Additional trains run between Times Sq and 74 St. BUS1 - every 10 minutes - Court Sq - 21 St - Queens Plaza/Queensboro Plaza - 36 St - Steinway St - 46 St - Northern Bl - 65 St - Roosevelt Av. BUS2 - every 10 minutes - Roosevelt Av - all stops - Union Tpk BUS3 - every 10 minutes - Roosevelt Av - Union Tpk - Van Wyck Bl - Jamaica Van Wyck - Jamaica LIRR - Parsons/Archer - Parsons Bl - 169 St - 179 St.

Is there demand for 12 minute headways on the B4?

No trains between 125 St and 168 St. Stop at 135 St. Stops at 155 and 163 St. NEXT No trains may pass 59 St west of 5 Av. Affected:

So there IS a continuous express track along the Dyre line? It's not on the track maps and I can't find it on Satellite View in G-maps. Thanks for the clarification.

How does that work? The track maps don't show any usable express tracks.
