For nearly a decade, RTD’s FasTracks project to extend light and commuter rail across the Front Range has slogged along at a frustrating pace, producing few tangible results. Not anymore. The brand-new West Rail Line is in its first full month of operation. What’s more, the 12-station route from Denver to Golden was completed eight months ahead of schedule. (Yes, you read that correctly.) We can only hope the line to Denver International Airport is up next.
