Well if you're talking about using these dead end layup tracks south of BB (the ones off Tk 1 that DON'T go to the loop) to get those trains to the SF loop, those tracks can't be connected because of the superelevation of the mainline track north of Fulton.

As for switching S/B <6> trains north of BB from Tk 1 to Tk 2 to get them to the Green, that would cause delays for the reasons Relay posted, particularly considering that if there is a (4) or (5) in the station, not only is that <6> held outside the crossover but any (6) behind it is jacked up. Likewise that means REALLY slowing express trains through Canal which means timer city, otherwise it will never fly. You Gotta reduce the express speed through Canal S/B, especially since a <6> train might be switching over onto 2 track in front of that express or sitting on 2 at BB and that switch needs to be reset for the express to proceed through. The point I'm trying to make is it's not that big of a service improvement to justify the costs and delays associated with it, cuz all that adds up to a lot of slowing down.

Also you got the confusion of the geese at BB N/B who suddenly got (6) and <6> trains showing up on both tracks...

It seems to me like a much better implementation of the spirit of this idea would be that <6> would be renumbered (8) and would run express from Pelham Bay Park and then replace the (5) on Lex Ave express and further destinations (Bowling Green, Flatbush, Utica). The (5) would then run local down Lex Ave along with the (6) and both would terminate at Brooklyn Bridge. Nights and weekends the (8) would not run, and (6) would be extended to Pelham Bay Park from Parkchester, and this roughly matches the service pattern for Brooklyn since the (5) does not run there during this time either. (Or some service pattern could be implemented where (8) runs limited service through to Bowling Green when the (5) would have otherwise done so).

The only switching issue with this plan occurs at 125th street where basically all 4 possible routes are used, so there is more switching needed. I am not sure how much this could slow down service there - may still be prohibitive.

And of course the question still remains about whether this is really needed... and how (5) riders would react... neither of which I can really speak to, but it seems to me like the necessary effort is likely not to be worth it just to have <6> service run express all the way down Lex. But as stated before I know very little about the Bronx ;\)

Let's make this simple:

1) Taking Pelham Bay trains and running them as Lexington Avenue express trains is BAD - whether

a) we call them #8 trains or leave them as #6 trains;

b) while the 125th Street station can handle the switching duties, the Brooklyn Bridge station can not;

c) the riders will be confused about what train goes where and holding up the service - which means that there is something to be said for "stability" of train routes;

d) just because the switching capability is there does not mean that we have to use it - yes Pelham or Jerome trains can be equally local or express at 125th Street - big deal.

e) Taking the Pelham Bay trains away from the Lexington Avenue local (by making them express) leaves too few trains (Parkchester) to handle the amount of riders at the local stations. Even diverting a few #4 or #5 trains to serve as locals again "jams up" the line with riders confused about what train goes where, and huge amount of daily riders.

f) Transit fans like to think about every possible route that could be made, to ask "what if" -- which is very different from actually running a railroad that has to transport millions daily.

g) Considering that the TA runs the trains, one would have thought they could have come up with this "new bright idea", on their own. Or is that maybe this "new bright idea" is just no so good after all. What does the TA know, they "only have to actually run a railroad".

h) One could actually look at Lexington Avenue as a "system" for moving trains not as switch points to "play with the trains". The #4 and #5 lines are merged/split at 149th Street, and again at Franklin Avenue - in between the trains can just simply run. If all goes well, the #6 does not have to switch tracks with any other line at any station - so the trains can run fast.

Just a few thoughts,
Mike

i agree with you on d-f-g-h for sure... i was just playing "what if" like you mention ;\) especially i think h is the best point... it does create extra merging/splitting... which can provide more variety of service (think about queens blvd!) but can create bottlenecks as well.

on b-c-e however, you misunderstood me...

b) my plan does not create additional switching in the brooklyn bridge area, since cars running down lex local would always terminate there, and all express trains would run further south.

e) my plan would take ALL 5 trains and run them local on lex, so that would provide the needed trains for lex local service.

c) riders would not be confused because ALL 4-8 trains are express, while ALL 5-6 are local. it is a service change from the present, but it is self-consistent. perhaps a clearer way to state an equivalent plan would be that 5 service (staying express on lex) would be rerouted to pelham express, and a new 8 service would be created to fill the gap in WPR service, running local on lex.

thanks for your thoughts!

The current pattern is the best. The same destination can be achieved with a transfer anyway.

From a previous mesage: "riders would not be confused because ALL 4-8 trains are express, while ALL 5-6 are local. it is a service change from the present, but it is self-consistent. perhaps a clearer way to state an equivalent plan would be that 5 service (staying express on lex) would be rerouted to pelham express, and a new 8 service would be created to fill the gap in WPR service, running local on lex."

Before the 1950's on the westside IRT lines at 96th Street, there were local and express trains that travel to/from Broadway, and local and express trains that traveled on Lenox Avenue, with express trains coming from the Bronx. The trains from 241st and 242nd Streets were the express trains to/from Brooklyn, while the local trains to South Ferry both operated out of 137th Street-CCNY, and 145th Street-Lenox Avenue (and that is why that station is a short station holding only 5-cars).

The 96th Street was the switch point and bottle neck of the system. Why? While a local train traveling up Broadway, and an express train traveling up Lenox Avenue did not cross paths, the other routes caused switching problems. The TA tried several approaches to remove the bottlenecks at the station. When a Broadway express reached 96th Street it had to be switched to and from the express tracks. When a Lenox Avenue local train reached 96th Street it had to be switched to and from the local tracks to and from the express tracks that lead under Central Park. Hence there are two routes whose trains cross-paths. These routes also block trains that are "straight-routed" on the tracks. The TA decided about 50-years ago to do away with this scheme, and to create what today we call the #1, #2 and #3 lines - where at 96th Street, none of these routes cross paths, each are "straight routed" lines.

Now let's look at your idea. Again you would have #4 trains as express, #5 trains as local, #6 trains from Parkchester as local, and #8 trains from Pelham Bay as express. The switch point would be the 125th Street station. At the 149th Street-Grand Concourse station, #5 trains would have to be merged into or split from the path of #2 trains, to join (or depart) the stream of #4 trains. Then again at the 125th Street, these #5 trains would have to merged or split from the path of #4 trains, to be merged and split from the path of #6 trains. Of course, #8 trains would have to be merged and split from the pathways of #6 trains, and again merged and split from the path of #4 trains.

Thus at the 125th Street-Lexington Avenue station only the certain pairs of trains could proceed through the station approach tracks without interference - one pair consists of the #4 and #6 trains. One advantage of the 125th Street station is that #5 and #8 trains could proceed through the station at the same time. This would require some major league scheduling to make sure that the pairs always line up the same way. If an uptown #4 and an uptown #5 train entered the station at the same time, one train would have to wait for the other to proceed before it could proceed, blocking the train behind it. Similarly if an uptown #6 and an uptown #8 were to arrive at the same time, one train is blocked from proceeding.

The same sequence of trains would have to happen on the downtown platfrom, only pairs of #4 and #6 trains, and pairs of #5 and # 8 trains could use the station at the same time. Every other combination blocks a pathway for a train, and the one behind it. Right now there is no such blocking or switching of trains, (emergencies of course and G.O.'s do not count), allowing the quick movement of trains into and out of the station. The dispatchers do not have to care about what sequence of trains is using the 125th Street station, since none of the sequences blocks another train.

There is another issue, the #2 and #5 are "paired lines" where if there is a problem with one route, the trains are routed to the "other" pathway. Sometimes #2 trains will travel down or up Lexington Avenue to or from Brooklyn, or #5 trains will travel the westside. Thus when there are problems, the trains can be "returned" to their place of origin.

Your scheme of sending #5 trains to Brooklyn Bridge, creates more problems than it solves.

Just a few thoughts.
Mike

Making the 5 a Lex local(bronx express) and the 4 and the 6 the Express is not a bad idea this would justify ridership on each line.


The 6 is bronx express only to have those people pour out of the train at 125th street (stay with me let me explain) if that train continues express then it relieves the crowds at 125th street.

The 4 and 6 prooves they have the crowds the Pelham line Proves that an express service was needed in the bronx meaning that high service could be needed in Manhattan


The 5 is express in the Bronx due to length and the areas it serves. (bringing the working class North Bronx )

The 5's transfer point for express service can be 149th street grand concourse people who really is on schedule would have the option to get off there as well as 125th street.

I would'nt have the 5 terminate @ brooklyn Bridge it will run it's course but the train will be local in Man. maybe extend the 6 express to Bowling green at rush hours the issue there is the two track issue that can work for and against . it against if there is a delay in Man. but a another resource if there is a delay in Brooklyn meaning that wall street riders will not be delayed if there is a 6 train coming from bowling green.


I am not to familuar with the track switching in that areas so i bet some of you will enlighten me on that

To note ...


People seem to forget that after 9/11 this experiment took place when the 5 was going to parkchester. and some riders actaully loved it to have an express ride from Man to parkchester

Yes, all of the lines are crowded in both Manhattan and the Bronx but it isn't very justified here - ALL of the liens are crowded and that's just due to high ridership. Besides, instead of having a one-seat ride and changing all three routes you can just make a transfer at any express station.

The 5 running local could just the line running later into the bronx due to the Lex avenue local traffic this is the biggest reason haha


the 6 even running express will still have it's ridership as would the 4 train.

The crowd rushing at 125th street needs to be calmed and the rush is not for nothing other than express service so this is proof that maybe the cluster of crowds on the lex line would be more evened out the line and not have the express trains become sardine cans especially @ 86 Street

I dunno, I'm starting to think that the current pattern of service along the Lexington line is fine...I think that perhaps one should wait until the completion of the Second Avenue Subway is evaluated before switching around the current East Side service. Yes, the express trains are packed, but won't the few locals be even more packed?
Any way you put it, the East Side will be packed.

Niot really becasue you have to remember the pattern .

the 5 is express from 180th to 149th that is basically 20 stops if you count both divisions .

the 4 may get a boost at 149th

and the 2 may inherit riders

The 6 has its ridership because it's a local and not an express. 77th Street, 96th Street, 68th Street and 51st Street are examples of stations where tons of people get off and on.

The six bronx ridership is deep it is over crowded with the 77th 96th 51st street type stops. while the 5 bronx rider ship @125th is the lowest and in fact is the emptier train of the three.

6 EXPRESS will still be crowded.

the current pattern is good but people forgot this was done already with basically the 5 running to parkchester after 9/11 and in fact the customers loved it

well, uhh, let's have:

4 trains run express in brooklyn, local in manhattan (north of brooklyn bridge), and local in the bronx... just for kicks, ya can have peak direction service in the bronx as well...

5 trains run local in brooklyn (some to utica, some to f'bush), express in manhattan, and local in the bronx (service to 238th eliminated)...

6 local trains remain unchanged in both boroughs it serves
6 express trains run express (on the express tracks) in manhattan north of brooklyn bridge (it's current terminal), run express in the bronx; peak direction... up to Parkchester...


...and that, my friends, is how you f*** up service along Lexington av.


if you (threadstarter) don't see where I'm goin w/ this, in regards to the thread title & how ridiculous I think this idea is, then don't bother....

Oh, I see what you're sayin... you thought I meant service along utica av, in that little tirade of sarcasm I had goin on there... nah, I was simply referring to the Utica av/eastern pkwy. station...

as for your reply here... yes, in this date & time, subway service along Utica av would be heralded!



I still disagree w/ sending 6 express trains, express in Manhattan.

6 shud go thru bowling green loops nites tho- as it has on occasion- requires no extra trains just does cut virtually all the recovery time at south end of trip.... wah wah.. the current arrangement is best tho- depite that atleast 4x a/ week i experience a 6 battery run- and i get on at local manhattan stop- no help to me-i would toss in a pelham exp from bowling green or hell even GASP new lots like maybe 3 or 4 trains in the am/ pm rush....ok so not new lots but definitely to bowling green, the switch at 125th sb is no big deal, yes lex is at capacity but there are gaps that can be exploited>>> and wat a treat whn a pelham exp via lex exp arrives at 125th nB no need to transfer trains or sb...
a lot of changes could be implemented if crews on trains and pltfrms were more aggressive in moving trains... and rebuilding switches to allow say 30mph not 10-15.. to this is perhaps a space issue since u cant just tear out walls o make switches longer and more gradual ala metro north/lirr

the FACT is the 6 and the 4 are the most crowded of the three lines meaning there is another line to work with in terms of crowd control and for the record the lex lines is already f**Ked up. the 5 can easily be the lex ave local because it's riders have three different options to switch and two express trains transfers before it hit manhattan while the six is crowded from 125th to pelham and is the bronx line that covers alot of real estate for it's line probally has the most area to cover for it's riders and the most distance between another train line in the whole bronx.

From a previous message: "the 5 can easily be the lex ave local because it's ..."

Please, please think in terms of the track maps, the capabilities of the actual stations before entertaining another thought about the #5 train as a local.

In order to have #5 trains as the local, #6 trains as the express you will have to have trains switching to and fro between the local and express tracks. There will be situations where the tracks will be blocked - for example with both a #$ and #6 train arrive at 125th Street and they both need to use the express tracks downtown, or when both #4 and #5 trains traveling uptown arrive at 125th Street. Your "suggestion" results in a reduction of smooth operation. At the Brooklyn Bridge station, your "suggestion" is even WORSE since all switching would be done on the same level, when only one train (either direction) can switch from one track to another. This is basically a bad idea - it will tie up the tracks for no benefit to the riders.

However all of this has been explained in detail in the previous messages.

This weekend there will be a small, partial opportunity. The (6) in the Brooklyn Bridge-City Hall direction will run express from 125th to 42d Street-Grand Central from 11pm tonight to 5am Monday. As the (4) and (5) do, the (6) will stop at 86th and 59th Streets.
