RTD’s A Line under repair at Union Station for track settlement
DENVER -- Work to level the A Line track at Union Station is underway, requiring passengers to walk a bit farther to board trains. Track One at Union Station has settled a half-inch dip (well within Federal Railroad Administration tolerance, according to RTD). The dip is forcing trains to stop at a different location along the platform to avoid an area of the platform that is not level with train cars.
