Crews had inspected the Orange Line between Clarendon and Foggy Bottom and did not immediately find anything. Service is back to normal on the Blue Line.
Dan Stessel, a Metro spokesman, said it not known how long the latest round of single-tracking will last on the Orange Line.
Stessel said the earlier problem on the Red Line where there was a power outage was “not obviously weather related” but due to an arcing insulator outside of the Glenmont station. He said the transit system had seen a “much higher number of equipment problems due to cold weather” Wednesday.

Metro riders faced disruptions and delays Wednesday morning on on all five of its rail lines and to its bus service because of the snow and ice.
At 10:30 a.m., Metro said it was going to start single-tracking on the Orange Line between Clarendon and Foggy Bottom stations so crews could begin inspecting track in the area area. Metro spokesman Dan Stessel said several trains reported “mechanical problems” after passing through that area. He said the problem is not believed to be a cracked rail, which can sometimes happen in very cold temperatures.
It was unclear how long the single-tracking would last. Metro said riders could experience delays of 30 to 40 minutes.
Metro did resume normal bus service on most of its routes by 10 a.m., after initially limiting service to snow emergency routes because of bad road conditions. All but six routes were back to normal. Those lines included the 3T, the D12, the D14, P12 and the E6.
Earlier problems on the rail lines included a power outage outside Glenmont on the busy Red Line, door problems on several trains on different lines and a disabled train on the Green Line. But most of the problems were resolved by 10 a.m.
Stessel called Wednesday morning’s commute “choppy” but said there had been no “major disruptions,” prior to the single-tracking. He said the agency ran eight car trains later in the morning than it normally would because the federal government opened two hours later.
The Washington Post’s Capital Weather Gang said temperatures are expected to remain frigid throughout the day Wednesday and officials warn that could affect transportation routes on buses, trains and roadways.

Trains are no longer sharing a track on the Green Line, but delays continue in both directions.
An Orange Line train also had to off load at Metro Center and that created delays on the Blue and Orange lines.
Dan Stessel, a Metro spokesman, said the problems have been related to door problems where blowing snow got “ingested into the door tracks.”
Other trains have had brake issues, which is the result of trains coming from the tunnel into near zero degree temperatures, it affects the brakes on a train, he said.
“It’s been a choppy morning but nothing I’d describe as a major disruption.”
He said Metro buses should go back to normal service within the next half hour or throughout the day as weather conditions improve. The buses had been operating on just snow emergency routes because of the snow.
Metro also ran more eight car trains later in the morning because the federal government opened two hours later.
