"The Metro North West Line currently operates with 6-car trains running on 4-minute headways. After the addition of the Stage 2 extension to Bankstown, the stations’ platforms will be configured to allow for future use of 8-car trains and the signalling system designed to allow for 2-minute headways, both of which are planned to be introduced once increased patronage demands it. Eight-car trains have a design capacity of 1,539 customers and increasing the running frequency to ultimately 30 trains per hour (2-minute headway) would provide a maximum capacity of 46,170 passengers per hour per direction." https://en.wikipedia.org/wiki/Sydney_Metro#Capacity

Unlike backward Greater Vancouver, Sydney makes it easier to have longer trains to better handle future capacity.

Fortunately, Sydney builds to NSW standards, not the backwater standards of backwards BC.
