Wouldn't 2000 be a very long/full train by American standards? The NYCT trains I looked at recently topped out at 1500. (I know, I know, we are substandard...)

The main problem on the red line isn’t trains or signal capacity, but pedestrian flow on-off trains at stations.
-
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!)
