My 2 cents on the matter, I agree with bcp.
On the subject of the train station, it's hard to see how they will put a four track station at the CML. We may eventually get a new station elsewhere, and trains going southbound may have to go north before going south.
But hey, could be worse. Look at our competition for
Grand Central West. They've got all our problems! Lawsuits, stimulus dollars, a stub hub. Even though it doesn't pertain to Denver, it's an interesting read, and the technical requirements are applicable to either any future station in Denver, or any expansion at Union Station.
