Posted by Concourse Express on Sat Nov 21 08:31:38 2009, in response to Re: V Running/D Local on Weekends, posted by R30A on Fri Nov 20 19:26:21 2009. Concourse-Concourse riders would not benefit whatsoever.Concourse-4 line riders would not benefit whatsoever. Concourse- Washington Heights/145th riders receive no benefit either. These riders wouldn't benefit from a (D) local either. In the best-case scenario the 8-min headway is retained (no change from current pattern). However, this requires adding (D) trains to compensate for the local run; if this isn't done, you stretch the headway, which increases wait times. For these riders such is NOT beneficial, but detrimental. This detriment, in addition to adversely affecting ALL (D) riders, reduces the benefit to CPW local riders. Concourse-8th ave riders receive no benefit either. How so? Given that such riders would transfer at 59 for 8th Ave service, an express is certainly advantageous over the local; the time savings increases the probability of connecting with a (C) thats already on the CPW lcl run (this eliminates waiting time on the transfer). In the worst-case scenario such a connection isn't made and the riders would wait for the next (A)/(C). This, however, is the best-case scenario in the (D) local case; as a local, (A) express trains could pass (D) locals, increasing wait times on the 59 x-fer. Concourse-CPW riders are HURT by the D running express. True, but such ridership is insignificant compared to the rest of the ridership to/from Concourse. Such riders can transfer to/from (C) service at 145 or 125; with the exception of S/B riders traveling to 135 or N/B riders traveling from 135, the transfer is cross-plat - hardly inconvenient compared to many other transfers. Concourse-125 riders are slightly hurt by the D running express. I assume you're referring to the switches and timers b/w 145 and 125 that eat up potential time savings. Even so, it's hardly a case of running the (D) local - it's a case of addressing the speed restrictions (AFAIK, the signals along CPW haven't been replaced yet). Not only that, it's still possible for expresses to save time on this stretch - it's happened to me many times. The ONLY destinations for which Local D service would not benefit CPW riders are 50/8, 155 and 163/Amsterdam. What about the rest of 8th Ave? A (D) local doesn't make a difference there either; such riders need an 8th Ave service - which they already have in the (C). As such, I still stand by my belief that improving (C) service is MUCH more beneficial overall than a (D) local. *** my blog |
