20tph and 2000 per train. 1000 per train isn't even full! Expect more riders with higher frequency, more still with improvements to cleanliness etchttps://twitter.com/apocalypsepony/status/1049625012888641537 …
that makes much more sense to me--I was gonna say, no way 15k/hr is at capacity from the perspective of the trains and frequency

Vicious circle too. You cut frequency to save money, more people per train, longer dwell times which make it harder to maintain frequency.
-
Dwell time up to 2 minutes because of pedestrian flow/platform crowding forces headway. Yes a vicious circle. Headway’s were sub-2 minutes back when they had real signals instead of modern gee-whiz technology. Still not as high as achieved on the Garfield Park El in Chicago.
-
cutting platform dwell time w/o rebuilding all the stations is just a matter of adding more doors per car
-
I think it is driven even more by access/egress on the platforms to the mezzanines. I recall the downtown stations being terrible in this regard.
-
that's a factor in moving people around the station, for sure--and some are worse than others--but for getting people into and out of the train quickly, adding more doors to the car works (they did this in Japan in the 90s to great effect!)
-
I think the trouble at the doors stems from crowding in the platforms which is driven by headways and egress. Less people waiting with more trains, but outflow critical to emptying people getting off quickly out of the way to allow boarding.
-
it's related, yes, but you can still cut dwell times with doors alone--then focus on rebuilding/redesigning stations

compare: 3 doors per car on existing Red Line fleet vs 4 per car (typical Yamanote Line fleet) or 6 per car (select carriages on various lines around Tokyo)pic.twitter.com/14cvmlkDqU
