T to Dyre Avenue Posted June 17, 2017 Share #5426 Posted June 17, 2017 (edited) Short turning Js at Broadway Jct would leave stations east of there with less service, something they need badly seeing as with skip stop, they're already only getting 6tph. To add 4th av service, I'd just extend the south to 95th, 9th, Bay Parkway or 86th (whichever is most efficient, and given more cars of course).Sorry...I meant run the short-turn trains in addition to the existing and service, so as not to leave the stations east of the Junction with less service. They should probably have a different letter, like K, so as not to cause confusion with the skip-stop / . Extending the to Bay Ridge would certainly help out the as well, but would have to wait for the R211s to enter service.

RR503 Posted June 17, 2017 Share #5427 Posted June 17, 2017 Instead of building the to terminate at Hanover Square, why not merge it with the Jamaica Line on Broad Street and use Montague to service 4th Av? You could do that, but a) the engineering of a 2nd ave-nassau connection is difficult (see 2av thread -- ppl have posted about it) and b) doing so limits you to ~18tph from 2nd ave to Brooklyn. If we're looking solely in terms of impact on Brooklyn service, building a connection to the Fulton St local tracks via Court Street gets you the biggest bang for your buck.

Problem is, the Williamsburg Bridge can only do 24tph. and run 12 together, and the runs 9ish for a total of 21. Do you really want a new service with ~3tph? I'm all for s down 4th in theory, but you have to consider route length. 1 Quote Link to comment Share on other sites More sharing options...

LongLiveRock Posted June 17, 2017 Share #5429 Posted June 17, 2017 The problem with sending the to Bay Ridge is you wind up having to deadhead trains from CI Yard to Bay Ridge somehow, which would both waste time and disrupt service. Perhaps a permanent terminal of Kings Hwy or 86th-Gravesend on Sea Beach would work, though that could be a messy merge after 59th... Alternatively, you could send it down West End, but Sea Beach needs the extra service more (based on ridership), and since trains are run with crews, I'm sure logistically running it down Sea Beach makes more sense. Also 45th and 53rd are high ridership stations that could use some extra service (especially when 53rd re-opens). 0 Quote Link to comment Share on other sites More sharing options...
RR503 Posted June 17, 2017 Share #5430 Posted June 17, 2017 if that's the case what happens to the museum? I would suggest one of the abandoned platforms along the Nassau St. Line or the lower level of 9th Ave. The problem with sending the to Bay Ridge is you wind up having to deadhead trains from CI Yard to Bay Ridge somehow, which would both waste time and disrupt service.

Porter Posted June 19, 2017 Share #5433 Posted June 19, 2017 Instead of building the to terminate at Hanover Square, why not merge it with the Jamaica Line on Broad Street and use Montague to service 4th Av? I'd support that. It sounds less expensive than building Seaport and Hanover Square stations, both of which being located in very dense, confined, and delicate areas. At any rate, the Nassau Line needs to be seriously rethought; its current layout is obsolete and a waste of space. 0 Quote Link to comment Share on other sites More sharing options...

Lance Posted June 19, 2017 Share #5437 Posted June 19, 2017 One does not preclude the other. Nassau St does not need service from Second Ave to get those station and line rehabs. Besides, the proposed Water St alignment provides service to an area that currently does not have any subway service, whereas the Nassau St alignment serves an area that's practically over-saturated with subway service. Along with the Nassau St line, there are the lower portions of the 7th Avenue and Lexington Ave lines providing service in the Financial District. I don't believe a line from Second Ave will be that beneficial, even with the population growth in Lower Manhattan. Another thing to consider is the terminus of this potential service. Would it terminate at Chambers St or Broad St in Manhattan or would it run to some point in Brooklyn? If it terminates in Manhattan, all it has in its favor is a relatively easy terminal that doesn't require much new construction beyond Delancey St. If it were to run into Brooklyn via the Montague St tunnels, it would undoubtedly run into the mess that is DeKalb Ave junction. It would not be impossible to run a 2nd Avenue - Montague - South Brooklyn route, but unless some major construction is done in that area, the train holds approaching DeKalb Av would only get worse as this new service mixes with the existing Broadway and 6th Avenue services. 1 Quote Link to comment Share on other sites More sharing options...

Which as much as I would like to see a Nassau connection done, Water Street is more important, especially if from there it can proceed to Brooklyn via a new Schermerhorn Street tunnel that connects such to the Fulton line. 0 Quote Link to comment Share on other sites More sharing options...
2Line1291 Posted June 20, 2017 Share #5439 Posted June 20, 2017 Quality over Quantity, the Second Ave Line is better off being built along Water St and a future extension to Brooklyn via an Atlantic Ave Tunnel. Like Wallyhorse said, and 2nd Ave service along Fulton Ave Local and in my opinion the other one going down Culver Express and local south of Church Av. So far as DeKalb Junction goes, I understand the wonderful perks of flexing our subway services but I'm just looking at DeKalb and see trains flows better down 4th Ave Seach Beach and West End, while trains flows better down Brighton. 1 Quote Link to comment Share on other sites More sharing options...

Around the Horn Posted June 20, 2017 Share #5443 Posted June 20, 2017 @Deucey I learned something new tonight How so? I have a sense of where you coming though Well, first off there's now no way for passengers from 4th Avenue to Broadway to catch an express train without walking through the transfer tunnel at Atlantic, and the same for 6th Avenue from Brighton, as the 4th Avenue express tracks lead directly to the DeKalb bypass (and the only switch from the express to the local to stop at DeKalb has a 5MPH speed limit enforced by wheel detector IIRC). And because of all that, you've now turned Atlantic into a madhouse. 0 Quote Link to comment Share on other sites More sharing options...
Porter Posted June 20, 2017 Share #5444 Posted June 20, 2017 Even if the SAS were to reach Hanover Square (will any of us be alive?), couldn't it connect to the Montague Tunnel anyway without passing through any Nassau Line stations? That tunnel is underutilized and it's not worth the money to build a new one. 0 Quote Link to comment Share on other sites More sharing options...

I think there are unused bellmouths, but I'm not sure if they are on the right side of the tracks for a connection to Water Street. The problem with that is that you are forced to go through the crowded DeKalb junction, unless you build an expensive junction in Downtown Brooklyn. 0 Quote Link to comment Share on other sites More sharing options...

Lance Posted June 20, 2017 Share #5447 Posted June 20, 2017 It's possible. It would just become a matter of where to send this hypothetical service. 4th Avenue, the local tracks specifically, is the only South Brooklyn line that could use more service. Running this service anywhere else would likely just add more service where it is not needed. Of course, we're looking at this from a present perspective. Who knows how ridership patterns will be in the 22nd century? To respond to another suggestion, shifting the to the Sea Beach in favor of the as a Brighton line is a terrible idea. This not only ignores the ridership of the Brighton line entirely, which enjoys 19/5 6th Avenue service along with full-time Broadway service. It also ignores off-hours riders on the Sea Beach line while skewering service over to the Brighton needlessly. Unless Transit were to run train service at all times between Manhattan and Brooklyn, service along Sea Beach would once again be relegated to a shuttle with riders forced to transfer to the and for continuing service. This issue also manifests itself on the Brighton line because both the and are considered primary lines currently and would likely remain so, even if they both were to share the Brighton line with one running to Astoria and the other to the Upper East Side. That means Brighton riders will see two services that run between Manhattan and Brooklyn at all times, including late nights while Sea Beach riders would have none. I cannot see how riders would accept such an idea. The present setup is not perfect, but it is much better than the post-Chrystie/Manhattan Bridge construction service revival that's being proposed here. 0 Quote Link to comment Share on other sites More sharing options...
bobtehpanda Posted June 21, 2017 Share #5448 Posted June 21, 2017 That sounds more feasible and reasonable than building a dedicated tunnel, to be honest. A new bellmouth can be appended if need be. It really isn't. The brand new tunnel makes sense because it allows you to fully utilize SAS's capacity, whereas using Montague caps southern SAS capacity at DeKalb's remaining capacity, which isn't a whole lot. Building a tunnel under a whole lot of nothing (the river) is also a lot cheaper than trying to weave additional capacity in and out of DeKalb; if that was feasible, then they would have done it during the countless modifications to DeKalb in the past. 1 Quote Link to comment Share on other sites More sharing options...

Have the stop at Bay Plaza (Y) Eastchester Rd/Pelham Pkwy Esplanade/Pelham Pkwy White Plains Rd/Pelham Pkwy Southern Blvd/Fordham Rd Fordham Plaza Morris Av/Fordham Rd (connection between Concourse and Jerome lines via platform) Sedgwick Av/Fordham Rd Dyckman St, then all stops to South Ferry I made these suggestions because running the (Y) from Bay Plaza to Queens (basing it out of Rockaway Park and Jamaica Yards, Jamaica accessible via a track connection to the yard leads at 71 Av) would effectively replace the Q44SBS north of Jewel Av and take most of the traffic off the Q53 bus south of Metropolitan. It would wind up dramatically reducing loads on the Q50 as well, and would finally give Co-Op City subway access. You'd also wind up creating a link between the Queens Blvd, Rockaway, and Jamaica El lines on a preexisting ROW the way the QueensRail plan would, but without the inconvenience of having a shuttle line or the operational risks of extending the or any further on the northeast end. Adding a 7 Av service on Fordham Rd/Pelham Pkwy (and splitting the TPH evenly with the 1 train) should take most of the load off the Bx12SBS, and allow for greater flexibility for people coming in from the North Bronx. The connection to the Concourse line at Grand Concourse should allow for load shifting off the Dyre and WPR lines onto Concourse IND trains, thus reducing some of the crush loading on the WPR.
