Metro riders have experienced long delays due to a derailment, a brake problem, a door problem, a medical emergency, and a train that was offloaded and turned back to improve spacing. And that’s just from one Thursday in August.

This visualization shows how many long delays (at least 10 minutes) Metro had on each day this year. Click any day to see details.

Note: The data is based on what WMATA tracks in its service report archives. This doesn’t include times when trains were scheduled to be more than 10 minutes apart. So if Metro was only running trains every 20 minutes some Sunday, that wouldn’t count in the data. It only includes unscheduled service disruptions, like a train being halted for brake problems.
