Metro said riders on the Blue and Orange lines should expect delays Friday morning.
The problem is the result of an earlier train malfunction at L’Enfant Plaza.
The delays are in the direction of New Carrollton on the Orange Line and Largo Town Center on the Blue Line.
The Red Line had delays earlier Friday because of a train malfunction at Brookland.
