The Water St Subway would have allowed the V train to run straight into Lower Manhattan rather than terminating at 2nd Ave.<<<Could not agree more. Another way into/out of Lower Manhattan would have been a much better way to spend that money, along with extending the existing SF platform to hold 10 cars and add additional exits. |

I already know about Van Cortlandt, but Will mentioned SF as well, and I certainly disagree with your statement only because there is no actual information about it describing it in detail. All you can see now is the bright blue tunnel leads heading down and the diagrams dating back to 2005, when the whole project was still pending....and on a side note...the new SF tunnel kind of reminds of the German U-Bahn U7 tunnels except with brighter lights. |

(was:Re: Would 4-track express service...), posted by (SIR) North Shore Line on Thu Sep 6 20:24:52 2007. WillD, I'm not sure if you've been down to South Ferry lately, but throughout August, during the height of the PM Rush Hour, there was almost always three trains below Rector St at any given time. One is usually at the station, and two are waiting behind it. This happened to me every weekday afternoon and caused me to miss quite a few boats. I'm not sure about those absurd numbers brought about, as the (1) is quick as-is, but it frequently gets clogged with a few trainsets outside of South Ferry. Then South Ferry, has the whole issue of the narrow staircases and the platforms becoming dangerously crowded as people hurdle to form single lines up the steps.One can now see the new SF Terminal lead tracks and the routing down there looks to be so much more direct than the current loop route. HOW MANY TIMES HAVE WE TOLD YOU THAT THE "BACKUP" YOU SEE IS NOT CAUSED BY THE SOUTH FERRY STATION? NO MATTER HOW MANY TIMES YOU FORGET WHAT WE TELL YOU, YOUR VERSION OF THE FACTS IS NEVER GOING TO BE CORRECT. |

'I don't think El-Train meant rush hour.'El-Train actually said: 'You'd think that with the 9 train being canned that there would be much more frequent 1 trains running, but the headways are still annoyingly long (5+ minutes)' The 9 only ran in the rush hour, so I assumed he was referring to rush hour. The 9 was irrelevant otherwise. |

'if you increase terminal capacity somewhere north of 96 St sometime in the future''And the likelihood of that is what - something on a par with the chances of the proverbial snowball in hell?' Well, that is the precise likelihood of anything whatsoever being done about this problem in the next fifty years. But, if the MTA became convinced of the need to do something aboput headways on the 1, creating an intermediate terminal at 137th would be a lot cheaper than adding a fourth track, or reconfiguring the junction north of 96th. |

What WillD was saying was that plenty capital money could be *saved* by more sensible spending (or non-spending) in other places, namely the rebuilding of South Ferry terminal and the Fulton Transit Center, and the unneccesarily expensive alignment of the downtown end of the SAS (which isn't being built yet anyway, but we'll let that pass), sufficient to fund improvements to the 1 line. He wasn't saying that building a line to the Upper East Side was a good substitute for improvements to the lines to the extreme Upper West Side. |

What should be added are more trains on the local between SF and 137.Sure, it is the only solution, but what's the holdup on that? Lack of actual trains? Version 1: Operational practices -- the MTA are paranoid about passengers riding relays, so they have all trains thoroughly checked ("fumigated" in Subtalk terms) at the last station before a relay. This takes time and would delay the train behind. Version 2: But that paranoia is justified because those passengers might clobber the T/O as he changed ends. Version 3: If there were another track on the other side of the uptown platform, fumigation would no longer cause knock-on delays. And what's the problem with the Van Cortlandt Park terminal that I see more than one person alluding to? Just the typical problems with a two-track terminal without any tail tracks. |

(was:Re: Would 4-track express service...), posted by (SIR) North Shore Line on Thu Sep 6 20:24:52 2007. during the height of the PM Rush Hour, there was almost always three trains below Rector St at any given time.That's pretty good. The distance between the Rector station and South Ferry is approximately 2000 feet - measure it on Google Earth. Each train occupies approximately 800 feet: 510 feet for the train itself and 300 feet as a buffer between the trip arm and the back of the train in front. That means that those 3 trains below Rector need at least 2400 feet of track. One reason for backups at terminals is a result of the TA's "improved" on-time performance. One of the TA's strategies to "improve" on-time performance was to increase the scheduled running times. The running time from 242nd to South Ferry used to be 49 minutes; currently it's 55 minutes. The majority of trains did not need the extra 6 minutes, even when on-time performance was an abysmal 66%. They would arrive at their terminals substantially early. Trains were not released from terminals early. The result was that all the pockets at the terminal were probably filled up for two-thirds of arriving trains at terminals. The result was instant backup. How long a backup? The recovery time at the terminal is 3 minutes plus the additional off book recovery time of 6 minutes from the inflated schedule for a total of 9 minutes. Service levels are 20 tph for 3 minute headways. So, 9/3 = 3 for 3 trains in limbo. H'mmm..... |

Instead why not, south of the existing crossover from the uptown local track to the middle track, put in another crossover from the middle track to the downtown local. Now the T/O can walk along the platform instead of through the train... O.K. - downtown passengers from 137th have to play 'guess the platform'.

With, presumably, uptown trains carrying on to Van Cortlandt PArk using the new blue track, and terminating trains using the existing uptown local track. These terminating trains would relay in the yard, using the new blue crossover to reach the downtown local track.Exactly. And there's a small "park" above where the new uptown through platform would be, so disruption would be fairly minimal (and the neighborhood could be bought off with a nicer park at the end of it all). And you might have noticed that I drew it as a London-style cross-platform transfer (i.e. two caverns with connecting passages), as that would avoid demolishing too much of the original 1904 station. But - it's a relay, so they have to fumigate. Yes, it's a limitation, but one that almost certainly would not be met in practice. Assuming South Ferry can indeed handle 24tph, then the obvious service pattern would be having 12tph relaying and 12tph continuing. And we already know that relay terminals can handle in excess of 12tph (look at Continental). Instead why not, south of the existing crossover from the uptown local track to the middle track, put in another crossover from the middle track to the downtown local. Now the T/O can walk along the platform instead of through the train... That would work, but it could well end up with passengers unexpectedly having a trip back down to 96th. Of course, there's a very good reason a relatively cheap construction project at 137 couldn't happen: finally having enough terminal capacity at that end of the line would really emphasize the quality of South Ferry. |
