Metro completes repair of Yellow Line tunnel leak; Yellow Line service restored

Metro has completed repairs to the Yellow Line tunnel south of L'Enfant Plaza where water was entering the tunnel earlier today. 

The leak was first reported around 11:30 a.m. by a train operator. Metro structural engineers and inspectors responded and determined that the water was entering the system from outside the Metro system. Third-rail power was de-energized for safety reasons.

From 11:30 a.m. until 2:30 p.m., Yellow Line trains were single tracking between L'Enfant Plaza and Pentagon City. Normal two-track service has been restored.

It has not yet been determined whether the source was ground water or from a non-Metro-related pipe outside the tunnel wall.

Customers should expect normal service for the evening commute. As a reminder, Yellow Line trains are scheduled to run less frequently due to SafeTrack Surge #13.
