I don't think anybody is sitting around deliberately twiddling their thumbs. The rail lines themselves are much larger, longer, and more complicated construction projects than single site buildings. I'm sure it's true that Union Station is extremely complicated in its design. But even if they had a design ready two years ago, I wouldn't have expected to see construction yet. FasTracks and the rail passengers it brings is the heart and soul of the development. There would be no reason to start on the project right now, they're trying to time its completion with the opening of the first rail line.
