Trains on the Orange Line will run every 24 minutes from 10:00 p.m. tonight (Friday) through system closing on Monday. The normal interval is every 12-20 minutes.
WMATA says the delays are necessary in order to facilitate various improvement projects.
“Crews will continue platform reconstruction work at Deanwood and Minnesota Ave stations, as well as track maintenance, fastener renewal, and grout pad rehabilitation between Stadium-Armory and Cheverly,” the agency said. “In addition, signal system testing will continue for the new Silver Line.”
