Recently I took the Amtrak California Zephyr west from Denver. Being in the back part of the train I was able to position myself looking out the back of the coach while we departed Union Station.
As we depart the station you will see all of the new development in that area. A little further in the timelapse, Coors Field will be on the left followed by a passing RTD University of Colorado A Line train which is heading to Denver International Airport.
