Posted by Michael549 on Sun Jun 28 13:23:04 2015, in response to Re: M to West 4th on Weekends/Late Nights, posted by WMATAGMOAGH on Sun Jun 28 10:58:31 2015. While Wallyhorse is looking at the IND subway as built/expanded, the IRT subways on both the west-side and east-sides were not really built to "mid-line" or "short-turn" terminate trains in Manhattan easily, while letting other trains pass by. A big noted exception is the established terminals.Wallyhorse posited the existence of a train route that ends at a certain station while other train traffic continues past that station un-affected by the terminating train route. For example: on the westside there is the 42nd Dtreet-34th Street 5th-track that could allow some express trains to end their run at 42n Street, while other train traffic continues to Brooklyn. This message is not about whether it should be done, but rather if it COULD be done in a way that does not interfere with the other train traffic. Of course there's the middle track near the 103rd Street station on the #1 line, or the long-time used collection of tracks north of 137th Street, or the middle track by Dyckman Street. Besides the 145th Street and 148th Street usual terminals, #2 like trains would have to be sent to north of 149th Street-Third Avenue to turn trains around. Any further north on the @2 and #5 lines there's the regular terminals and storage places. Note that for 14th Street and Chambers Street - traffic on the express tracks has to be re-routed to use those tracks for terminate relay operations. ------- On the Lexington Avenue line, there the middle track that is north of the 59th Street upper-level local platforms. Using both 86th Street and 42nd Street-Grand Central would require or work better with continuing train traffic re-routed. While there used to be a 5th track near the Spring Street station, the usual terminals (loop tracks) at Brooklyn Bridge and Bowling Green would have suffice. Similarly as the train route travels further into Brooklyn or the Bronx, the usual terminals come into play. On the north, there are the 138th Street-Third Avenue station, the 149th Street-Grand Concourse upper level station, or the previously mentioned middle-track north of 149th Street-Third Avenue to turn trains around. While the suggestion of the built/expanded IND system flexibility has been raised, a look at the flexibility on the other lines is also a good idea. Mike |
