According to the Cook County GIS, both the 606 and the C&NW Right-of-way are level at 600' feet above sea level. (Wouldn't it be cool if it was 606'?) The land surrounding the C&NW seems to vary between 590' and 599', mostly in the 593-596' range - except for the places where North and Cortland cross under, which seem to be lower than the prevailing elevations through this area, at about 585'.
Just laying down the roadbed and ballast alone would probably add 3 or 4 feet. So is there some earth moving? Yes - but you're not building up a 15' embankment. And even if it were, that's still just pushing dirt around.
I don't know anything about the costs of things like reconfiguring the interlocking, I suppose that could really bust the budget. But relocating Clybourn station to the south was also considered as a part of the Circle Line project, so it seems like this is something that lots of people think would make sense.
