Given Gawler/Seaford would essentially merge as one through line utilising new underground platforms - let's call them U1 and U2 - that immediately frees up platforms 1-5.
But then the issue moves from a capacity issue at Adelaide Railway Station to a capacity issue on the actual Gawler rail line itself.
Any new Two Wells /Riverlea line (branching off at Dry Creek) would complicate things a bit as it has to share the Gawler line tracks between Dry Creek and the Adelaide Railyards.
There would be capacity constraints due to the four level crossings at Hawker Street, Belford Avenue, Pym Street and Cormack Road. You would need to eliminate these crossings in order to be able to run higher frequencies to service the Gawler and Two Wells lines.
Not to mention adding a Concordia branch line to the mix presents additional capacity issues between Adelaide and Gawler as well. I do assume it will be Roseworthy that will be the extension of the existing Gawler line, due to the sheer scale of the proposed housing development, which far exceeds what is proposed for Concordia.
I think itd be easier to build a rail freight bypas thus freeing up the existing ARTC track on the Gawler line into a third track, which alleviates capacity issues by operating as a peak hour express track.

The Northern Connector rail bypass would definitely help, but only north of Dudley Park. IIRC the bypass would’ve branched off just north of GJR, while the corridor between there and Dudley Park is wide enough to add even two metro tracks.

They should be laying the rails down into these new areas now. It will literally never be cheaper or easier than before the developments happen, and they can make the lines run straight to town centres.

In the latest Greater Adelaide Regional Plan (see attached), it mentions a "mass transit corridor reservation" for Riverlea Park, Two Wells and Roseworthy. It also highlights insane growth for these areas, Riverlea Park / Two Wells is projected to have a combined population of 70,000 and a further 80,000 for Roseworthy, and that's excluding Gawler/Concordia. Absolute crazy stuff.
Where did you find this map, and have the maps for the other regions been released yet?

I've said this before but Port Dock could (and should) be realigned to go east around the Aviation Museum, there is almost enough of a vacant corridor to get a track running north along the P/R Expressway and then running west along the Northern Connector. This then shares some of the load with the Outer Harbour rail corridor.

How would this rail corridor get from the intersection of St Vincent St/Perkins Dr to the north side of PR Expressway?

It would run parallel with Perkins Drive. Some minor property acquisition would be required but minimal in scale compared to building a line elsewhere, and most of its is either industrial or commercial land so land-swapping with suffice for keeping that expense down.

I’m a bit confused by this. There is already a rail reserve via Rosewater connecting with dry creek? This would almost match that alignment surely? Also.. what load on the Outer Harbour corridor? 2 car sets every half hour or so is hardly crush load? Having said that, I’m all for linking the Port Dock with the Northern line or potential other northern spur lines. It allows for spreading employment opportunities for various communities, and allows the Port to develop as a CBD in its own right.

I think itd be easier to build a rail freight bypas thus freeing up the existing ARTC track on the Gawler line into a third track, which alleviates capacity issues by operating as a peak hour express track.
The other way to free things up and increase frequency would be to see the Roseworthy (or any other northern extension) to be coupled with the Flinders extension utilising the underground rail line and associated platforms. This would essentially make 2 seperate north/south lines.

Agreed I think this is the way to go.

Both the Concordia and Roseworthy extensions would be single track in my opinion, with a 30 minute frequency on both lines. Once the lines join at Gawler it would maintain the 15 minute frequency on the Gawler Line. Basically, the Gawler Central line would become the Concordia Line and the Gawler Line becomes the Roseworthy line.
The Flinders Line would be best joined by a new local, all stops service between Adelaide and Salisbury, with the longer lines running express between Adelaide, Mawson Lakes and Salisbury. This maintains the frequency on most stations (except Parafield and Islington) if the local service runs every 30 minutes.
