All clear on the Orange Line

12:30 p.m. Update: Metro reports that the Orange Line is operating without delays.

12:05 p.m. Update: Metro spokesman Reggie Woodruff said the agency is expecting a return to normal service within 30 minutes. A track circuit in the area is "bobbing," he said. Woodruff said the circuit in question was affecting the switching ability at New Carrollton, which was precipitating the delays.

Metro's train protection system is made up of track circuits, electrical systems embedded along the tracks that are capable of detecting the presence of a train.

Typically, crews must make adjustments to electronic signals that travel along the circuit when such problems arise.
