Metro resumed normal service Wednesday after warning that delays were possible because of a technical issue that caused problems monitoring train movements, Metro staff said.

Metro initially told travelers at 7:55 a.m. to expect “major delays” on all lines and plan for additional travel time. Normal service resumed about 10:30 a.m.

The network issue was “intermittently preventing rail operations from accurately monitoring train movements throughout the system,” Metro spokesman Ian Jannetta said in an email.

The issue also led to inaccuracies in arrival times listed on Metro’s website, Metro officials said. Travelers should rely on in-station signs for arrival information.

Metro staff is investigating, Metro spokeswoman Sherri Ly said by email. There were no reports of crowding at stations.
