Posted by SMAZ on Wed Jan 30 02:31:35 2008, in response to Re: SAS Phase 4: Water Street/Nassau Street, posted by Russ on Tue Jan 29 17:44:14 2008. Just the (J/Z) and a split (T) into Nassau. That about 20-24 TPH. The Queens SAS and the future Bronx SAS (which would split from the north bound (T) after 116th and terminate in the 125/2 miniyard and one day continue to the Bronx) would terminate at a Chatham Sq Lower Level. They could one day be extended down Water St to Hanover Sq. The (M) can merge with the (V). I'll make an example below. For the sake of sanity I'll refer to the other SAS service as the (U) and the Queens service as the (Y).Upper SAS: (Q) 125/Lex-CI 10-12 TPH (T) 125/Lex-Bay Pkwy via Nassau/Montauge 10-12 TPH (U) 116/2-Chatham Sq LL(and one day to Bronx)8-10 TPH Total trains on 63rd-125 SAS segment: about 30 TPH Lower SAS (T) described above (U) described above (Y) somewhere in Queens to Chatham Sq LL 10 TPH Total trains on 63rd-Chatham Sq segment: about 28-30 TPH at Chatham Sq the (U) and (Y) would descend to a Lower Level and terminate there with provisions to extend down Water St. That would be a terminal capable of handling 18-20 TPH. The (T) would stop at an Upper Level there and then join the (J/Z) under Nassau St. Nassau St (J/Z) as is 12 TPH (T) described above 10-12 TPH Total Nassau St: 22-24 TPH The (M) merges with the (V) This isn't some wild unrealistic fantasy plan. It's what I think is the best possible plan for a 4-boro two-track Second Av Subway. I hope that some MTA engineers are reading this right now. |
