I think there might be a timer before Jamaica bound and trains enter Sutphin Blvd, it’s been like that ever since I started riding the and and certainly before that too 0 Quote Link to comment Share on other sites More sharing options...

No, trains entering that station always slow to a crawl even if there’s nothing ahead. 0 Quote Link to comment Share on other sites More sharing options...
RR503 Posted March 24, 2019 Share #106 Posted March 24, 2019 The end of the is fraught. Entrance to Supthin is basically a permanent ST20 as the interlocking rarely has an established lineup through (and thus can't give trains clearance to enter at speed, lest they keep that speed through the station, trip the approach signal leaving and overshoot the home), and when they're storing trains in the tail tracks beyond Parsons, that station entrance becomes ST-only also so that you don't go barreling into the stored sets.

RestrictOnTheHanger Posted March 27, 2019 Share #110 Posted March 27, 2019 There has been a noticeable increase in speeds during the pm peak on the and northbound from Brooklyn Bridge to 42nd st. Trains dont crawl the whole way like they used to. Same can be said about the QBL express. Jamaica bound trains move at decent speeds now during the pm peak, despite the loads at Roosevelt Ave. Went to Forest Hills for the first time in a while and it seems the new 75th Ave interlocking has had its timers fixed. The I was on was moving at normal track speed, and it appears the delays associated with the interlocking timers are pretty much gone. 0 Quote Link to comment Share on other sites More sharing options...
MysteriousBtrain Posted March 27, 2019 Share #111 Posted March 27, 2019 I'm still waiting for the MTA to fix that timer that makes it seem like the is about to stop at 125 St downtown but it brakes too early. Makes me paranoid af. 0 Quote Link to comment Share on other sites More sharing options...
N6 Limited Posted March 27, 2019 Share #112 Posted March 27, 2019 trains don't slow down as much pulling into 71st Ave now. But still not as fast as they used to be. Are they going to address the downtown crawl on from Canal St to Chambers? 0 Quote Link to comment Share on other sites More sharing options...

I used to love being on the R32 or flying into 71 Avenue. 0 Quote Link to comment Share on other sites More sharing options...
RR503 Posted March 27, 2019 Share #114 Posted March 27, 2019 There are no timers entering 71 on the express tracks in either direction -- that area really only has the DGTs protecting the 75th ave switch. Crawling experienced has to do with dwell times and interlocking performance. They've supposedly raised limits on the n/b QB express track. Can one of our QB riders confirm? 0 Quote Link to comment Share on other sites More sharing options...

It seems faster, but I have been doing schoolwork, but I cannot say definitively. I will check tomorrow. 1 Quote Link to comment Share on other sites More sharing options...

I didn't hear any horn but I still passed it off as maybe some track work going on. Now that you brought it up I'm wondering what the real issue might be.. 1 Quote Link to comment Share on other sites More sharing options...

I saw a sign for 45 at the east end of Grand (it was 36 3 Sundays ago), a 50 sign at the west end of Woodhaven, and surprisingly a 50 sign at the west end of 67th. I saw a DGT30 before FH, a 25, 15, and then 20 at 71. Then there was a ST30, ST20, DGT25 and DGT15. I wrote this down after-the-fact, so I am quite sure that the signals before 71 are also GTs. Once again my waited for over a minute at 75th Avenue for an to pass over the interlocking. For the first time it what seems forever, and trains ran express on Queens Boulevard yesterday. 1 Quote Link to comment Share on other sites More sharing options...

The 45 and 50 signs are new — good to hear they’re in. I take it they’re not in any of the GTed sections? The DGTs you mention are only active when the switch to the relays from the express is lined for the relay. Otherwise there are no non-ST time signals active on D4 during regular service around Forest Hills save for the DGT that protects the 75th ave switch (of which there is only one, on the home itself). About merge performance at 75, look at this. Note how delays at 75 and weirdly long dwells at Roosevelt throw off the rush.

Yup, the merge performance really screws things up. Better dispatching is needed at JC and 179th. 1 Quote Link to comment Share on other sites More sharing options...
