Posted by Stephen Bauman on Sun May 13 11:03:09 2007, in response to Re: May 11, 1975. . .End of the Culver shuttle, posted by Avid Reader on Sun May 13 10:22:35 2007. First, NYCT should not schedule trains so that two are assigned to merge onto a single track at the same time. Second, NYCT should monitor the progress of trains so that they do not arrive at a merge point at the same time. These two obvious principles take care of the problems with the E, V and R at Queens Plaza.Regarding Canal St. First, NYCT should maintain switches in the straight position, when trains enter the station. Two, a diverging switch should be switched when the train is stopped in the station during that train's normal dwell time. Three, schedules should be designed so that an approaching train does not enter a station when another train is making a diverging move onto its track. Neither of these examples are relevant to Jamaica Center. Both the examples you cited are for two tracks with trains going in the same direction. Jamaica Center has two tracks with trains going in opposite directions. The only purpose for such a switch is to reverse directions. |
