       Riders on Metro should expect delays Friday morning on three rail lines.

       There are delays on the Blue, Orange and Silver lines because of a track problem outside the Stadium-Armory stop.

       Trains are sharing a track between the Eastern Market and Stadium-Armory stations.

       It’s not immediately known how long the delays will last.
