On the bright side, Green/Yellow stations north of Fort Totten have reopened.

On the downside, trains are experiencing speed readout issues (meaning they're having to travel slower) between West Hyattsville and Prince George's Plaza.

At 8am, Yellow and Green line trains are running with delays, concentrated mainly between West Hyattsville and College Park. Expect trains towards Greenbelt to hold at stations as directed by the ROCC and travel slowly in between.

Sometimes when #wmata does major trackwork they also replace ballast, the rocks under the tracks, which requires slow speeds while it settles and adjusts.

Today's speed restrictions are a combination of that plus add'l ATC speed command issues.

Green and Yellow line trains continue to suffer performance issues due to trains traveling slower on the outbound track north of Fort Totten (ATC circuit issue, apparently). I wouldn't be surprised if #wmata begins to turn Yellow line trains at Mt Vernon Sq at some point.

Trains are currently running every ~16 minutes when they're scheduled to run every 12 (and 10min during rush) due to ATC track circuit issues. But yes, they're open again. #wmata

There is no @Metrorailinfo alert for this delay.

This track circuit issue has been affecting trains since this morning's 5am opening.

Live look at the Yellow/Green lines, which are suffering from an ATC track circuit issue on the northbound track around Prince George's Plaza. Trains are delayed heading north & affecting southbound trains too. #wmata

UPDATE: Yellow Line trains are offload & turn around at Fort Totten. YL/307 at Fort Totten is first to turn around. Transfer to Green to continue north. #wmata

Indeed, #wmata is still experiencing an ATC circuit issue near Prince George's Plaza. Delays are much diminished since Yellow Line trains began turning at Fort Totten, but they're still affecting trains.

Yellow and Green line trains appear to be operating normally between Fort Totten and Greenbelt today. Yesterday's ATC issue appears to have been fixed. #wmata
