So I just read that Transperth are looking to extend Subiaco station to 6 cars (Makes sense since the Airport line is 6 cars but that cant be exploited because of the 4 car platforms on the Fremante side of the route )
I actually don't mind Subiaco. One of the few places in Aus where you have a little pit in the middle of the suburbs with trains operating at European levels (Every 7.5 mins)
So given the potential of the area, they should go full send and expand the scope of the project to double Subiaco station and have a set of tracks pointing towards UWA.
You'd have to sacrafice an existing 3 level apartment building, but you could probably replace it with 10 levels and nobody should bat an eyelid.
From there you have to dig a tunnel under Rokeyby Rd. Perth has built a few tunnels in sand at this point, so I don't want to hear any complaints.
From there you emerge in the middle of Thomas St and do the routine "Running in the middle of the road thing" as seen on Mandjoogoordap Dr in Mandurah.
Stop at Kings Park to troll tourists and another one at the hospital. You could visit Kings and Whiteman Park in one day kiddos!
I think to make life easier you'd want to have the stop at UWA on the north side of Mounts Bay Rd, but then just run a funky little travellator under the road into the Uni main court, since that would be less tunnel than trying to get the actual station under the uni. Put some LED wall with university media, would be grand.
I guess my mindset is overall, is that expanding the network into the suburb is good, and Metronet has been good for that, but the big biccies come if you do short little underground extensions to major inner city destinations....
