>>1039325I heard that Guangzhou metro line 3 were designed woth short train high frequency service in mind, initial it used 3 smaller cars per train which later extended to 6 per train, but the max amount of train per line there is still only about 30 trains/hours which is severely incapable of handling the passenger volume on the line thus they are now building another line that run parallel to it.
When the line was initially designed at about year 2002(?) they predicted the daily ridership of the line on 2017 would be about 30k/day with maximum up to 100k/day, howeber its daily ridership have already exceeded 2M/day by 2014.
Beijing metro line 4 also used 6 cars train but it can reach 35 trains per hours by making one of the terminal function as intermedoate stop, so that after trains unloaded passengers there they will directly run into depot and next train will come out of depot and thus there are no need to reverse the train there which made the frequency feasible.
The maximum frequency for metro and trains in Tokyo are also around 32/hours.
I think so far there are only few systems that can reach 40 trains/hours, like the Moscow one? but according to the report i am reading, the moscow system is benefited from their train only stopping for 30 seconds at each station which is made feasible by their grand platform that ease passenger movement, so I don't think that can be easily replicated?
