Time to relive Metro’s most aggravating days all over again.

This visualization shows how many long delays (at least 10 minutes) Metro had on each day this year. Click any day for details. The data is based on what WMATA tracks in its service report archives.

It’s not pretty. In one stretch in February and March, six weeks passed without a single day free of a 10-minute delay.

Note: 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.
