There have been 9 significant service gaps across all lines so far this morning—most of them on the Red Line, where trains are scheduled to be running every ~16 minutes per #WMATA, but our data shows there have been gaps of up to 40 minutes at times.

What do we consider a significant service gap?

Back-to-back train departure times from Metro Center (for the RD/OR/SV/BL lines) or Gallery Place (for the GR/YL lines) that are at least 1.5x scheduled headways (24+ minutes for RD; 45+ minutes for all other lines). 🤓 #wmata

With AM rush hour technically, officially over, we've clocked 5 additional significant service gaps since our last tweet, bringing the total number of significant service gaps observed so far today to 14. That's ~15% of all train trips that #WMATA has run so far. 😬

We expect these service gaps to continue popping up throughout the day with varying frequency; since 9:30am, there have been 5 additional ones.

For what it's worth, the Green and Yellow Lines have been spared so far. #wmata

With #WMATA now saying that Red Line trains will operate every 15 minutes instead of every 16, we'll be adjusting our significant service gap threshold for the Red Line from 24+ minutes to 22.5+ minutes, using the same '1.5x scheduled headways' formula we described earlier.

With peak fares once again being charged as of 3pm, here's an update on where things stand: we've recorded 10 additional instances of service gaps since our last update.

The ~60-minute waits between Orange, Silver, and Blue Line trains are particularly notable. #wmata
