Metro’s Red Line was back to business as usual Thursday morning after a small track fire stalled the morning rush hour.

The fire broke out around 7:15 a.m. at The District’s Metro Center station, the transit authority reported. Though the fire was quashed, trains were forced to share one track between Judiciary Square and Dupont Circle to keep things moving (or not). Trains were back on both tracks by 8:20 a.m.

At some point, free shuttle buses were used to schlep commuters between Farragut North, Gallery Place-Chinatown and Metro Center. But riders still ran into big delays. After all, it was rush hour, and a bus can carry just 50 pissed-off riders. Compare that with the 800 people who can fill a Metro train, the transit authority said.

The Metro Center station also serves the Orange and Blue Lines. It’s unclear if those lines were messed up by the incident.
