All Washington Metro lines return to automatic train operation
WASHINGTON, Dec. 28 (ZFJ) — All Washington Metrorail lines returned to automatic train operation (ATO) this year for the first time since 2009.
The Washington Metropolitan Area Transit Authority (WMATA) returned ATO to the Green and Yellow lines on May 23 and Blue, Orange, and Silver lines on June 15 after “rigorous internal training and testing and concurrence from the Washington Metrorail Safety Commission.” The Red line already returned to ATO in December 2024.
