Posted by Fytton on Thu Sep 6 07:36:52 2007, in response to Would 4-track express service be of any benefit for Northern Manhattan lines (1, A)?, posted by El-Train on Thu Sep 6 01:41:46 2007. '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) and the trains are packed'The 9 wasn't a separate line, it was just a skip-stop variant on the 1, using the same trains as the 1. Its abolition didn't create any more trains, any more T/Os, any more C/Rs, or any more track capacity on the line. So why should anyone think that that 1 trains would become 'much more frequent'? In fact the service *did* become more frequent at the stops previously skipped - they now get all the trains, not just half of them, in the rush hour. New Yorkers' conventional wisdom is that expresses are always a good thing. But in largely residential areas of the city like the extreme north west side, there may not be some stops that are markedly less used than others. If they are all roughly equally used, how do you decide which ones should be express stops? The local stops will get *fewer* trains than now, remember, unless you are going to double the service overall! Finally - why is the existing third track not used for peak-hour direction expresses, as on other lines? Answer - because of the configuration of the junction north of 96th, which sends the express tracks towards Central Park North and the local tracks towards the Broadway line in non-conflicting moves. If investment is justified to provide some express service on the 1 north of 96th, spend the money on remodelling that junction before you think about putting in a fourth track. But the real solution to your problem is that NYCT should run a more frequent service on the 1. Five minutes is too long a rush-hour headway; 20 tph (three-minute frequency) should operate. Even the noew South Ferry should be able to handle 20. |
