I don't know why Denver needs an absurd number of tracks. Given the ONE daily Amtrak train that stops there now and the planned EMU lines (and maybe the occasional Ski Train) there is more than enough platform space.

In the future, advanced signaling can wring even more capacity out of the station. If it ever gets to the point where Colorado has a network of intercity and commuter trains and enough traffic to justify a 10-platform station, I think that will be the time to build at a peripheral location like plenty of other great cities have done, and simply re-organize local transit to serve the new station (38th and Blake seems like a good candidate for long-term planning, or, hell, the vast areas of parking at Auraria). But that's at least 40 years into the future.
