Beautiful photos Sam!
I have been involved (with FRA) with both the DUS and Denver RTD project since 2005 and am still working with them for opening of the North Metro (N) Line from Union Station. I spent a lot of time there between 2005 and the opening of the A Line in 2016 and was always amazed with how fast things were changed and built in the surrounding area.
Just a note of clarification, the RTD lines at DUS are "commuter rail" and not "light rail". Light rail is more urban based, with smaller and slower vehicles. The light rail trains are the vehicles that arrive at the other end of the plaza or further uptown on California Street..
