A weekend day ridership average considers any one of 2 days: Saturday and Sunday. HOWEVER, this is not a comparison of a random average weekday's ridership to a random average weekend day's ridership (which would only be 1 day—Saturday or Sunday), in which case an individual weekday would reflect a higher average than an individual weekend day. I'm collectively referring to the weekend as 2 days as reflected in the MTA's statistical report under "Average Weekend," not Saturday's and Sunday's individually. Hope that clears up any confusion. That doesn't really mean that weekends have higher ridership than weekdays though, given that the average weekday ridership measures a total day, whereas the average weekend ridership measures two. 0 Quote Link to comment Share on other sites More sharing options...

Right, but neither weekend day is higher than any weekday, with Saturday being about 60% of the average weekday. That said and as noted upthread, you could have some sort of a rush hour on Saturdays from say 1:00-6:00 PM (not 3:00-7:30 that I posted earlier) as a lot of people do work Saturdays while many more do make trips out (though not like a weekday obviously). 0 Quote Link to comment Share on other sites More sharing options...

LGA Link N Train Posted March 7, 2018 Share #6187 Posted March 7, 2018 @bobtehpanda I agree with what you're saying however there are a few things that don't click. as a CPW/Concourse line. Would 145 st be modified? at 168 st. If they're going both local then wouldn't that create a merge. You can't deinterline Broadway without eliminating the and should go to Astoria. 63 st won't be able to handle and all together. And I'd do QBL as Express being and via 53. via 63 and Bypass. via 63 and QB local and since I'm proposing a elimination with both the and to Astoria.

By sending both the and to Astoria and putting the back in the Montague Tunnel and fully local, you've basically made the lower 4th Ave local and the Sea Beach Line into two branches of the same line. You could just have the letter for both branches, like the with Lefferts and Rockaway.

officiallyliam Posted March 8, 2018 Share #6189 Posted March 8, 2018 What about this service plan? This will work until SAS phase 3 is built (clearly a ways off) and assumes no Queens bypass, and minimal construction. There are a couple of problems, which I'll mention below. Norwood to Lefferts/Far Rockaway via Concourse/8 Avenue/Fulton Express 168th to Brighton Beach via CPW Local/6 Avenue/Brighton Express Bedford Park/167th to Euclid via Concourse Local/CPW and 8 Av Express/Fulton Local Inwood to CI via CPW Local/6 Avenue Express/Brighton Local Jamaica Center to World Trade via QB Express/53rd/8 Avenue Local 179th to CI via QB Express/53rd/6 Avenue/Culver Local, possibly Hillside Express with an extension to 179th Forest Hills (179th?) to Middle Village via QB/63rd/6 Avenue/Jamaica and Myrtle Local 96th (125th) to CI via Broadway/4 Avenue/Sea Beach Express 96th (125th) to CI via Broadway/4 Avenue/West End Express Astoria to Bay Ridge via Broadway/Montague/4 Avenue Local - based out of 36th Street Yard Astoria to Whitehall, peak hours to Bay Ridge via Broadway Local - also at 36th Yard A side note: would upper Culver riders flip out if the went express and a much-more-frequent and full-length was the local? This would allow the to run at almost-maximum capacity, and the de-interlining (above) would allow more reliable service through Cranberry to absorb some of the riders from Park Slope, and a more reliable 4th Avenue service would let more people change at 4th and 9th. Long-term, Bergen lower could be reopened. I get this would be quite a long shot, but is it even worth trying? Problems: Sending all the QB Locals to 63rd, while operationally efficient, could be practically poor, since 53rd will end up full while 63rd will continue to be underused. It also raises the problem of having no QB Local serve Long Island City directly, since 63rd skirts the center of the area by running to Queensbridge instead. It will allow, though, for better and service by simplifying the merges on 53rd St, and a Queens Plaza and 36th. Do I support the bypass being built? Probably (there are issues). But it isn't even in the works now unfortunately, so I'm not trying to plan in a way that is dependent on its construction. This simply won't work once SAS phase 3 opens, as the northern section couldn't support the , , and . 72nd could have been used to turn s, but that won't happen now. And the SAS to Queens service, while attractive, will create more ugly merges at 63rd Street and 36th in Queens, unless a bypass is built, which is a long way off. This could be mitigated by sending the back to Astoria and cutting the . Hopefully, though, this could be done with the going express at 57th and wouldn't mean a return of the horrible 34th/42nd merge. 1 Quote Link to comment Share on other sites More sharing options...
T to Dyre Avenue Posted March 8, 2018 Share #6190 Posted March 8, 2018 Overall, I like it. Though you’d either have to extend the upper level platforms at 50th and 8th out to meet the on the express tracks, or close the upper level platforms entirely in order to have them both run express on 8th Ave. Though it would be great to have them both be 8th Ave expresses, because then they’d no longer have to merge at Canal. Just getting rid of that merge would help improve service on both lines. As for the alone between Church and Bergen, I get the feeling it probably wouldn’t go over so well with upper Culver riders, much like having the as one of the two QB locals proved to be unpopular with riders (which is why I’d never suggest bringing the back to QB). And if you have an at “almost-maximum capacity,” then you really should have at least half the trains running local between Bergen and Church. Speaking of Queens Blvd, I feel it won’t work with just the as the local. Especially with only 480-foot trains and its flat junction with the , which limits service frequency. The rest of the plan I can (pardon the pun) get on board with. 0 Quote Link to comment Share on other sites More sharing options...

Speaking of Queens Blvd, I feel it won’t work with just the as the local. Especially with only 480-foot trains and its flat junction with the , which limits service frequency. The rest of the plan I can (pardon the pun) get on board with. I was thinking of a platform extension at 50th Street to allow s and s to stop there, since making everyone at 50th (a relatively well-used station) go to and from the lower level platforms would be a pain. Here's the thing about the being the Culver local: fundamentally, it is a bad transit plan and one I wouldn't ever suggest if we were building the network from scratch today (same with the layout of QB). People primarily want to go to Manhattan, not turn away from Manhattan at the last second as the does. That being said, though, I think that Manhattan-bound riders across the board would be better off because of the increased reliability. Lower Culver and 6th Avenue riders get better service, and upper Culver riders have a cross-platform interchange at Hoyt (which wouldn't be as crowded, since a full-length would distribute transferring riders more evenly along the platform) to more reliable and service. The plan simply makes the best in terms of train frequency out of the poor track layout that the IND left us. As for sending half the s local, I still disagree - because a frequent (maybe 15 TPH) service would have to fumigate at Church in the way of southbound s. The as the sole local means that its fumigation won't disrupt service and will keep a cross-platform transfer to service at Church and 7th Avenues. The 480-foot train is an issue, even if the runs as frequently as it possibly could. That being said, the loss of 2 cars could possibly be made up for by the fact that QB will be far more reliable without the merging in at Queens Plaza and the no longer capped by having to share river tunnel capacity with the more-popular . The flat junction at Myrtle is more of a problem, though; this could be alleviated by starting and terminating some rush-hour s at 2nd Avenue, especially in the AM rush, where there is little demand going to Brooklyn. In a more long-term basis, the flat junction can actually be eliminated relatively easily, with a bit of new construction: the new Queens-bound track will diverge to the right from the main line at Lewis Avenue, making a left onto Myrtle and running into one side of the old upper-level platform. This shouldn't cost too much, as the only properly new construction will be a few hundred feet of viaduct between Broadway and Lewis and Myrtle Avenue. 1 Quote Link to comment Share on other sites More sharing options...

Your proposal to have the and swap northern terminals with the and has merit.

Under this proposal, trains would operate between Ozone Park/Far Rockaway in Queens to Norwood in The Bronx via CPW express with trains operating between Euclid Avenue in Brooklyn to Tremont Avenue in The Bronx during non-rush hours. On weekdays, during rush hours in the peak direction, trains would run express between 145th Street and Tremont Avenue towards Norwood with trains running local along the Grand Concourse, terminating at Bedford Park Boulevard. The present-day portion of the between 145th Street and 168th Street will be served by trains with trains providing service north of 168th Street to Inwood, replacing the current service routing. 0 Quote Link to comment Share on other sites More sharing options...
