KUSA - RTD says that a server issue caused a delay on the A-line Tuesday morning.
Several A-line trains did not leave at their scheduled times.
The issue was caused by a server or communications issue in the dispatch center.
Early reports said the B-line was also part of the issue. However, no trains were affected.
The A-line runs from Union Station to Denver International Airport. The B-line goes from Union Station to Westminster.
