Ok, let's have a look...
Firstly, you've retained the notorious Rushall curve on the 'Metro 2' line or even worse, replicated it in a tunnel. The Rushall curve could be kept (or better still, singled with some curve easing) in order to connect the Hurstbridge and Mernda lines for non-revenue trains such as EMU stabling/maintenance depot movements, track maintenance trains and so on. However, it's ridiculous for for future Melbourne Metro 2 revenue services to use it - it's dangerous
, Rushall station isn't exactly a high patronage station and the speeds through the section are pathetic.
It would be a much better idea to start the tunnel dive at Merri, get rid of Rushall station and have an underground interchange platform adjacent to Clifton Hill Station (under Hoddle St or Mayors Park).
For the Fishermans Bend section, you've only got the station placement about right for 'Sandridge', although even then the name is meaningless. In fact the route you've drawn seems to mostly ignore the whole Fishermans Bend
urban renewal zone entirely; your Metro 2 tunnel seems to skirt to the east and south of it. I'd suggest having a look at this technical study
done in 2013 concerning putting a Metro line through Fishermans Bend - it's possibly outdated compared to whatever Fishermans Bend Integrated Transport Plan draft exists in the bowels of DELWP, but it gives you a good idea of the kind of routing and station placement that would be most beneficial and the ground conditions that help inform that.
I can see why you've plonked down proposed stations at South Wharf/Jeff's Shed and 'Port Melbourne' - they're a large trip generator and a light rail interchange, respectively. However, you've also duplicated the 109 tram light rail corridor in that section - what's the point?
On the topic of stations, having a station in the Fishermans Bend Employment Zone is also probably a bit of a waste. The Fishermans Bend Draft Vision proposes something resembling an east-west light rail travelling along Lorimer St to connect that area with the other precincts and the CBD and that's likely to be an adequate solution. Having a station where you've plonked it is an expensive and circuitous deviation for a route that connects to Newport Station.
Now, as for the 'Doncaster - Bacchus Marsh line - it's a tad fanciful. The Doncaster section along the Eastern Freeway is bonkers - it doesn't follow the freeway median (which is pretty much non-existent east of Bulleen anyway) but it follows the freeway's route, which means that it doesn't go anywhere near local suburban centres or even the middle of Doncaster. What's the point of a bloody line to Doncaster that skirts around Doncaster Hill where all the high-rise development is? That section also terminates in the middle of nowhere (and I've never heard of 'Ringwood Heights'). That area is best served with a busway/BRT or if there's enough money available, some kind of light rail that terminates at Doncaster Hill. Heavy rail is highly inappropriate for the terrain and likely future population density along that entire corridor.
