Just curious whether the Doncaster rail line ever gets built. I prefer not go through the freeway reservation and more nearer to kew junction and the housing though was deemed too expensive in the rail study. The preferred route that the study wanted was to run through a freeway reservation and only serve the outer edges of the suburbs and terminate at the park and ride. If chosen the cheap option it require an overhaul of the buses to serve the station and rely on huge carparks to attract people catching the train. Obviously Metro 2 must be built for either option so they selected the cheaper option, but honestly if they tunnelled through, development can flourish along the route and bring extra benefit. Is it worth the cost, Im not quite sure
Here's a map I came up with today: Go ahead and discuss this its awesome (uses part of the old city circle route)
Key; Green tunnelling, Red ground level with grade separations, Pink Cut and Cover, Black is possible extension using cut and cover.
I also feel the same way about the Airport rail line if it ever gets built. It could of had a route that served potentially three shopping centres but tunnelling made it expensive so chose the Albion route. But the possibility that HighPoint shopping centre gets a station and places like Niddrie, Kelior east, Airport West suburbs can also be served by a railway. Honestly think that the extra costs is worth the benefit having the rail line striking the middle of these black spots for fast easy access public transport.
Map for Airport rail line is here at last:
Key; same as previous
You can see the potential extension to Sunbury above.
