I get the impression from watching these videos that they've detuned the
acceleration of the Sydney Metro trains to about the same as the Perth
trains, slower at least than on typical European metros but faster than
Sydney suburban trains. (On the Prague video here, wait to see the
acceleration after the attendant changeover.)

I note that the Sydney Metro train reverses in 25 seconds. It would have to
be a pretty Olympian driver who could get from one end of the train to the
other and start up in that time! The Prague system is an older one with
GoA2 level of automation. The Sydney system is a GoA4 system.
