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! -cda

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 Track Maps (upon request) Uptown Central Midtown Downtown 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

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....

You got that right. The B44 and 46 would be filled with elderly though.
This is beside the point, but yeah, there's already a growing elderly riderbase on the B46.... that I have noticed the past few mos....
B35 via Church, if the extensions approved by The Board Of Estimate in 1968 were built, I think the (4) down Utica Avenue to Kings Highway and the (2)(5) down Nostrand Avenue to Avenue U would be cool today. 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.
