Phil didn't waste any time, I just got home from the 'Victoria Cross open day' and haven't had a chance to download my camera yet!
There are some architectural details they will come to regret -
the opening shot of Phil's video shows two brown 'covers' over the
running tracks - they are going to be absolutely hell to keep
clean - the 'slats' are going to trap dust and small bits of
litter, but the way they are constructed means any one cleaning
them will need 'working at heights' gear.
I've not been in any of the other new stations so I don't know if
they all have this detail or not. Certainly was NOT designed for
ease of maintenance.

There are no horizontal covers over the running tracks. I know the design you mean, but these (and afaik on all Sydney metro stations that have full height PSDs) are vertical walls. There should be very little dust fallout in these public areas. The platforms are completely screened from the trains, so there would be little infiltration of train brake, pantograph etc fallout. They must have some confidence in that, otherwise they wouldn't have all those white walls and ceilings throughout the station!
I was there, there ARE near horizontal covers over the running lines, the design will be difficult to clean. It won't get dirt from the trains, but people are pretty dirty too. Probably more so than the mechanical interactions of the train with their infrastructure. See attached photo I took this morning at the 'Community Day'.
The brown part is over the tracks (I think there are air conditioning ducts between the running tunnel and the top of this structure) and it will be a trap for dust and debris. There are slats running length-ways with what looks like black painted board under the lengthwise slats. Any loose paper or lolly wrappers that end up there will stay up there. There are also places where people could toss stuff onto them from the concourse. But with the height above the platform below, any one going to clean them is going to have to have fall restraint - but there is no obvious attachment points for their harness. So I guess it won't get cleaned until it gets disgusting and they bring a EWP down the lifts one close down weekend and clean it.
The station design is a dirt trap. Otherwise appears to be well designed station to move people in and out. Lots of escalators and lifts. Wide passages.
But they seem to have missed easy to clean and easy to maintain.
The areas you can't see are probably larger than the public
spaces, the station also contains at 11kv substation, LV switch
rooms and a traction supply substation - and a significant amount
of 'air handling' equipment.

There are also not enough seats, but since the maximum you would be waiting is 10 minutes I'll give em that one.
The former ECRL stations have open topped running lines - at North Ryde where my sister lives, you can look down onto the roofs of the passing trains. (And if so inclined throw things at them.)

I recall being told back when I smoked, that smoking multiplies the effects of asbestos up to 10 times, compared to a non-smoker.
I’m still here after smoking, working with asbestos and working with polychlorinated biphenyls (PCB’s) in electrical equipment.
I still remember a safety manager in the 70’s saying that he would drink some PCB transformer oil to prove it was safe. We wouldn’t let him!
There were also the guys who used transformer oil as hair oil and wondered why they lost their hair.
Fun times.
Cheers,
Mick in Brisbane, getting a little bit OT
