Metro to begin Automatic Train Operation for the first time in 15 years

Return to ATO delivers increased speed commands -- safer, smoother ride

For the first time in 15 years, Metro trains will operate in automatic mode, a move that allows the system to operate as it was originally designed. Automatic Train Operation (ATO) controls the trains’ acceleration, deceleration, and speed while being regulated by safety critical equipment. Trains will get signal and speed commands from equipment located between the tracks for a smoother ride, enhanced safety, and improved on-time performance. Metro will operate in a semi-automated mode with a train operator always inside of the operator’s cab.

“This is a historic day for Metro operations,” said General Manager and Chief Executive Officer Randy Clarke. “Our team’s commitment to returning to ATO implementation has been nothing short of amazing. With the Board of Director’s support and expert advice from our peers, we were able to work closely with the Washington Metrorail Safety Commission to receive concurrence for this final step in the process.”

ATO will improve the experience for customers and train operators alike, allowing for coordinated arrivals at transfer stations and improved efficiency for customers transferring lines. Operators will remain responsible for the safety of the customers aboard their trains.

ATO is semi-automated and assists train operators with their duties. This will allow train operators to observe safety concerns and the environment around the train, including monitoring track conditions, train status, and door operations. ATO will not be used during inclement weather, during single tracking, when workers are on the roadway, and other conditions.

"Automatic train operations represent significant advancements in safety and efficiency for Metro customers and employees,” said Principal Director and Chair of the Board’s Safety and Operations Committee Don Drummer. “ATO also offers numerous advantages that contribute to an improved trip experience, increased reliability, cost savings, and more environmentally friendly train operations.”

Over the past decade, Metro has successfully included additional layers of protection to improve safety for customers and train operators when trains run in ATO mode. Those upgrades include:

• Implementation of preventative maintenance cycles that align with manufacturer recommendations

• Adjustment of track marker coils to track train location more precisely

• Implementation of train detection tools, which pair with our control center software solution, to allow traffic controllers to act on potential safety risks

• Replacement of older generation track circuits with a new, more reliable model

Metro has been preparing those whose roles include operating, controlling, and maintaining ATO for several months. The training was designed by Metro in coordination with Metro’s Safety & Readiness department and reviewed by the WMSC. Training includes classroom and simulator exercises, including the use of procedures that match real-life operations.

The first phase of ATO rollout will begin on the Red Line Dec.15 and extend to other lines in 2025.
