Not my drift at all. I'm saving that if stations had passing tracks in their initial design, there would be some advantages.
That would not replace the need for RoW & rolling stock maintenance.
And yes the platforms would had to have been spaced slightly further apart.
I addressed that here. A passing track whether it be between the mainline tracks of a twin platform station or splitting the platform of an island platform station would make the stations wider. For a twin platform station it would be 16' to accomadate a walkway and support columns in the tunnels at either end of the station, 11' when splitting the platform of an island platform station. Such a schema would more then double the interlocking infrastructure. Any way you slice it, a configuration like that would have increased the costs to build and more importantly the costs to maintain.
Never said it should do that. I want it to serve the terminal itself, not the parking lot. And an open-air station is oh so attractive on nights like tonight [29F, 20 kts] & mid-August vs. an underground one.
Had all the parties involved been willing to pony up the additional roughly $750 million I wouldn't be photographing the construction of the station in its present location.
