DENVER -- Problems persist for RTD's new commuter rail line to Denver International Airport.

Riders on Tuesday morning dealt with delays of up to 30 minutes. On Sunday, they faced delays of up to an hour for a period of time.

The A Line has had its share of delays and setbacks since the new line began passenger service at the end of April.

RTD said it's working to fix a complex electrical and computer guidance system that is responsible for causing many of the problems.

The transit agency points out the train line's performance is improving. On-time performance is running at about 90 percent, according to RTD.

A second commuter rail line opens Monday. The B Line will run between Union Station and Westminster.
