Metro expects to have fewer trains for Tuesday’s commute after pulling 100 cars over the weekend due to a safety defect that can cause doors to open while trains are moving.

Metro officials say they expect lighter ridership all week as locals vacation.

Typically the agency runs 850 cars out of its 1,118 fleet during the peak commutes — about 70 of them the Breda 4000 series that have the faulty door motors. So riders can expect shorter trains or somewhat less service.

Spokeswoman Lisa Farbstein said Metro officials hope to return four to eight to service per day, with workers working overtime to get the cars fixed. They are all expected to running again within about three weeks.
