Yesterday WTOP’s Adam Tuss broke the news that Matthew Matyuf, Metro’s superintendent of the Automatic Train Control Division, was back on the job for the first time since the June 22 Red Line crash (the Post followed up this morning). Days after the crash, which an ongoing NTSB investigation has tied to a faulty track circuit within the rail system’s automatic train controls, Matyuf was reassigned to a “special project,” but as of Monday, he’s returned to his normal duties. The move turns out to be tied to this piece of news, also from WTOP, that the NTSB is reportedly close to wrapping up the initial part of its investigation and is expected to make a major announcement on its findings in the next couple of days. Matyuf was moved away from his primary assignments in order to “preserve and protect the integrity” of the crash investigation, the Post reports, but now that the most intensive part of that investigation is wrapping up, he’s been allowed to get back to work.
