The track maps show that between 135 Street and 145 Street, the (B) has to share tracks with the (D) for like a few inches then cross over to the middle track to terminate.

 

Obviously whenever an uptown (B) and (D) arrive/leave at the same time at 125, one of them has to get held at 135 St to let the other proceed first, which in turn, delays the uptown (A) and (C) behind them. And a downtown (D) can't enter 145 if a downtown (B) is crossing ahead of it.

 

Oh, got confusing on the wording. But then why can't a (D) train enter 145th Street?

The same reason your car can't reach the inner lane of a highway right after merging in from the access road. By design, the traffic already on the highway and the traffic coming has to cross paths.

The Concourse Line was originally intended to be four tracks, but unfortunately, that plan dropped. If it were four tracks, there would be little to no delays at the 135/145 Streets area. Also, the (D) would have been a weekday-only Concourse Express, while the weekday-only (B) would have been extended to/from Bedford Park Blvd at all times except nights.

If the 4 express tracks were added on the Concourse, I would change the following:

161 Street would be converted into an express station.

(B) and (C) would have to switch their northern terminals.

(A) runs local north of 145 Street weekends.

(D) runs express north of 145 Street at all times except nights. Also, local late night service is added on CPW to replace the (C).

Why was rush hour (5) service cut back from 241 St to Nereid Av?

What BM5 said. Plus, there's no need for train crews to bring the train into 241 St without contesting the terminal and reversing direction (then going to the yard or to Manhattan). The (5) only runs on upper WPR in the reverse peak direction anyway. We don't want 241 St to become another Flatbush Av, do we? That's why.

It sounds like 4 services are enough for every line that has them...

 

A pair of tracks can hold 30 TPH tops. If you have two services, you can split 15 TPH between them, but with three you can only get 10 TPH. Running a third service would mean cutting service on other lines by 33%.

 

Also, for reliability purposes, two is easier to deal with than three on the same pair of tracks.

Would Fifth Avenue be fit for subway service? It could complement the Second Avenue Subway in curbing overcrowding on the Lexington Avenue (4)(5)(6) line as well as the M15 bus.

 

The Upper West Side area has the Broadway-7th Avenue (1)(2)(3) and Central Park West (A)(B)(D): that's two corridors. As for the Upper East Side area, the Lexington Avenue (4)(5)(6) will soon be joined by the Second Avenue (Q)(T). Again, that's two corridors. That's enough as it is. What more subway corridors do you want? You also have the buses as well.

with CBTC on Queens Blvd, what is the max possible capacity of the express tracks, also asuming they resolve the issue at Jamaica Center.

I just got an idea!

 

How about a crosstown (X) train that runs from 207 Street to Pelham Bay Park serving 207 Street in the (1) and 225 Street on the (1) and Fordham Road on the (4) and East 180 Street on the (2)/(5) and Zegara and Pelham Bay Park on the (6)?

 

Nobody will ever ride that. Just not enough demand. That's why we have buses for areas with lower demand.

The Bx12 is the third busiest bus route in the entire city, and was one of the first SBS routes for this reason...

Maybe not (X). That sounds like a fairly roundabout route, but a subway route running across Fordham Rd and Pelham Pkwy is not out of the question since there already is a turnout to access the 207 St Yard in that location.

Maybe an extension of the (A)? Then again, the (A) is already long enough...

 

That line would definitely be used, if it runs on Fordham Road & Pelham Parkway. The stations you planned wouldn't necessarily be used as a subway line..not to mention how zig-zagged it is.
