Now that RTD’s line from Denver Union Station to Wheat Ridge, Colorado, is open, train traffic around DUS can get downright busy. In this view looking up the throat of the station’s trackage—from left to right— is an outbound RTD A Line train headed to Denver International Airport, an inbound A Line train, a westbound G Line train bound for Wheat Ridge and an inbound G Line train. In the background on the far right on Track 8 is a B Line train waiting to depart for Westminster, and almost lost in the catenary supports and wires is a late-running westbound Amtrak California Zephyr.
