Dwell time is one of the headway components. It's critical that dwell times don't differ from the schedule. It's equally critical that scheduled dwell times are sufficient to meet demand. |

When NYCTA's R44's were brand new, the door closing chime sounded when the c/r pushed the closing buttons the chime sounded...………..then a delay of 3-5 seconds before the door would close w/o any more action by him.But when the doors actually started to close if someone was getting on the c/r had to reopen the doors so the passenger would not get struck by the doors. Now he hits the close buttons (door to his left and doors to his right), the whole cycle starts again. Now you have excessive dwell time. In the early days when the cars started on the Queens IND, if you see an R44 come in, there was a good chance of a "regular" train right behind it, especially if it was an F, thanks to the lengthy trip time. AT a certain point, the delay feature was modified to when the c/r pushed the closing buttons, the doors closes w/o delay. |

If a "door closing" announcement was part of protocol, however, then any further chime/delay when the button was pressed was unnecessary.A number of other systems around the world don't have a doors-closing announcement as a regular thing so the chime/buzzer is all there is to warn; then a delay for the warning tone seems more appropriate. |

On the R-44 and R-46, the closing chime sounded as the closing cy let began. Ultimately, with the delay set to zero, the chime sounded as the doors began to close. In no longer served a function. |

Other than for “window dressing” that’s correct. I believe there is some sort of federal mandate that requires warning chimes but it probably doesn’t specify how long the delay must be so NYCTA set it to 0. |

Plessey v Ferguson redux? The whole idea of public transit is freedom of mobility. This means the parent w/ a stroller, the elder w/ a walker, the person w/ a laundry cart, rolling luggage, wheelchair users etc who might any of them be your companion heading to some destination, are all entitled to use the transit vehicle together.And as for the "handicap vans" I can tell you from my friends who sometimes use them,booking 2 days in advance with a generous (extra hour) scheduled departure sucks. |

The stupidest thing is that the blinking lights, for the deaf who can't hear the announcements or chimes, start blinking with the chimes as the doors close, when they're not needed (since the deaf can see the doors closing). The lights should blink as the announcement is made, so the deaf have the same warning the hearing do. On the new-tech trains, with the automated announcements at the push of a button, it ought to be easy to make this adjustment. |

But on the other hand, and the octopus has many other hands, Everybody suffers if dwell times are increased. What was and should be a forty minute ride will easily become a 60 minute ride.A system that runs by the second has not place of extra seconds. ROAR |

Basically right now the light blinks to let the deaf know that the chimes are sounding that tell you that the doors will close within 0 seconds!For NYC, to practically attain a useable delay with the chime and blinking light without reducing dwell time, I would say just get rid of the "Stand clear. . ." announcement. When the C/R wants the doors to close, just press the button. There will be a delay, but that time is recovered by the lack of a prior announcement. |
