Metro to launch Automatic Train Operation on the Green and Yellow lines on May 23

Automatic Train Operation (ATO) is coming to the Green and Yellow lines on Friday, May 23 after rigorous internal training and testing and concurrence from the Washington Metrorail Safety Commission.

ATO controls a train’s acceleration, deceleration, and speed. Trains get signal and speed commands from equipment located between the tracks for a smoother ride, enhanced safety, and improved on-time performance. 

Train operators will continue to work in the cab and will still be responsible for the safety of the customers. With ATO taking over some tasks, operators can better observe safety concerns and the environment around the train, monitor track conditions, and close the doors when passengers are safely onboard. 

ATO is not used during inclement weather, single tracking, and when workers are on the tracks.

ATO improves the experience for customers and train operators alike. Metro began operations on the Red Line last December, reducing travel time on end-to-end Red Line trips by 8 minutes. Since implementation, there have been no safety issues or red signal violations for trains operating in ATO.
