Crews have repaired a water breach that was reported inside of a Yellow line tunnel close to L'Enfant Plaza Thursday, Metro said.
Metro got a report of water entering the Yellow line tunnel just south of L'Enfant Plaza around 11:30 a.m., according to officials.
Crews removed the third rail power on the inbound Yellow line track. Engineers then found water breaching the tunnel wall under pressure. Metro took action to stop water from spraying on the electrified third rail.
After several hours, Metro completed repairs on the leak.
There was no risk to the structural integrity of the tunnel, officials said.
Yellow line trains were single tracking between L'Enfant Plaza and Pentagon City. Normal service has since been restored.
It is not clear at this time where the water is coming from. Officials believe the water is coming from outside the Metro system.
