The commuter rail line connects DEN to downtown Denver in approximately 35 minutes via the RTD’s University of Colorado A Line train. This leaves from Denver International Airport with a stop at Denver Union Station. The train runs every 15 minutes during peak hours and every 30 minutes during non-peak hours. The public transit center will also serve as the pick-up and drop-off location for all RTD buses.
