Metro to launch Automatic Train Operation on the Blue, Orange, and Silver lines on June 15

Six months after launching Automatic Train Operation (ATO) on the Red Line, the entire Metrorail system will be operating in ATO starting Sunday, June 15, when the mode rolls out to the Blue, Orange, and Silver lines.

This development marks the first full return to ATO since 2009. The date was decided after rigorous internal training and testing and concurrence from the Washington Metrorail Safety Commission. Since the December 2024 implementation, there have been no safety issues or red signal violations for trains operating in ATO.

“This is a major milestone for Metro, and it has been a long time coming. I want to thank the team for their dedication and commitment to making this happen,” said Metro General Manager and CEO Randy Clarke. “This is a win for customers and staff who will experience safer, more reliable rides. Meanwhile, Metro is saving money as ATO is more cost efficient.” 

Along with the return to ATO, Metro is also returning to the original speed of the system, up to 75 mph. Several outer portions of the Blue, Orange, and Silver lines will see speed increases from 55 mph to 65 or 75 mph in some stretches. 

Starting June 22, Metro will reduce end-to-end travel times by about 3 minutes on all three lines. The Yellow and Green Lines, which began using ATO in May, will also see decreased travel times of 1-2 minutes. 

Based on analysis of several months of successful ATO operation in passenger service, end-to-end Red Line travel times have been reduced by a total of 8 minutes. Metro is continuously monitoring the performance of ATO, and additional time savings on the Blue, Orange, Silver, Yellow, and Green Lines may be incorporated later this year.

"Metro’s full restoration of Automatic Train Operations after 16 years is a transformative achievement," said Metro Board Chair Valerie Santos. "This advancement drives critical improvements in operations, efficiency, system safety, and the customer experience. It positions Metro firmly on the path to delivering the world-class transit system our region demands. The Board is unwavering in its commitment to advancing every improvement that elevates Metro’s safety, service, and performance."

About Automatic Train Operation

ATO controls the 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.
