Re: Re: Sydney Metro reaffirms safety and reliability (What is meant by 'metro'?)
  TP

Perth currently has a line capacity of about 18,000 people per hour per
direction (4 minute headways) with the present signalling. When the HCS
project is complete and the C series trains on line, it will have a
capacity, if required, of 36,000 pphpd, some 50% more than the capacity of
the Sydney suburban system.

https://infrastructuremagazine.com.au/2022/03/10/high-capacity-signalling-to-maximise-perth-rail-traffic-efficiency/

That's based on six-car trains, which the system is designed for. The
greater potential capacity of Sydney Metro is based on eight-car trains.
