Metro on Monday will being testing a new software program designed to provide a real-time back-up to the rail system’s crash-avoidance system, Lena Sun reports in the Post. The software was developed by WMATA and Annapolis-based developer ARINC following NTSC recommendations after the deadly June 22 Red Line crash. “With the software, a malfunction will trigger a visual and audio alarm on controllers’ screens at Metro’s operations center; controllers will be required to acknowledge the alarms.” It’ll be tested for the first time during Monday’s rush hour, with no set timeline on when it might go into full and complete use.
