Metro said riders should expect delays on its Blue and Red lines Wednesday morning.

Trains are sharing a track on the Red Line between NoMa-Gallaudet and Rhode Island Avenue because of a track problem outside Rhode Island Avenue. There are delays in both directions of the Red Line.

On the Blue Line, riders should expect delays because of an earlier train malfunction at Benning Road.

It was not immediately clear how long the delays on the lines would last.
