And this dear readers, is why we test our software….

Metro’s alert system continues to fail periodically in the area of track where one Metro train crashed into another last month, killing nine and injuring more than 70 people.
A component of the automatic train alerting system that may have failed to prevent one train from knowing another was stopped ahead on the track continues to flicker intermittently in that same spot even when new equipment is used, National Transportation Safety Board member Debbie Hersman testified Tuesday. The device removed just five days before the crash as part of routine maintenance doesn’t fix the problem, either.
The revelations were part of a three-and-half hour congressional oversight hearing in which officials testified about the deadly June 22 crash and the transit system’s overall funding shortages and lack of regulation.
The continuing problem at the crash site is why Red Line riders are still experiencing delays along the line more than three weeks after the crash.
Inexplicable failures of software happen.
