One of Metro’s new 7000-series trains had to stop and offload all passengers due to a software problem Monday afternoon, and Metro says that all of the new cars are due for a software update to fix problems soon.

Mike Tolbert, a Metro spokesman, said he could not share any details on what is wrong with the software. But Metro expects the company that manufactured the new trains to provide a software update soon.

On Monday, Tolbert said, the operator noticed that something was wrong, and stopped a Red Line train at Fort Totten at about 3:45 p.m. All passengers disembarked.

Tolbert said that sophisticated new trains necessarily are prone to sophisticated new problems. “These types of issues are not uncommon with new equipment,” he said. “It’s like your car. A car built in 2015 has a lot more software than a car built in 1980.”

Meanwhile, Mayor Muriel Bowser rode a new train today, while promoting a new program that lets schoolchildren ride the Metro for free.
