Metro single-tracked trains between two Yellow Line stations for three hours as workers sealed off a small hole that was spraying water into a tunnel, according to a news release.

Trains single-tracked between L’Enfant Plaza and Pentagon City stations on the Yellow Line after a Metro train operator reported seeing water entering a tunnel near L’Enfant Plaza Station around 11:30 a.m. Thursday, according to a news release. At 2:30 p.m., the Washington Metropolitan Area Transit Authority reported workers repaired the tunnel leak and restored the formerly de-energized track to service.

Metro had shut down third rail power south of L’Enfant Plaza to prevent water from making contact with the electrified third rail, according to a Metro news release. Metro engineers found “water breaching the tunnel wall under pressure,” upon inspection, according to a news release.

Metro spokesperson Richard Jordan said Metro structural engineers determined there is no hazard with the structural integrity of the tunnel.  

According to a news release, Metro believes the water came from outside Metro. Metro advised Blue and Green Line riders to also allow additional travel time because the agency expected the Yellow Line trains that were waiting to pass through the single-track zone would create congestion in the tunnels,
