Update, Sunday morning: Bustitution continues as workers repair the third-rail damage at Broadway.
The Boston Fire Department ordered the Red Line shut in both directions around 10:05 p.m. as the station filled with smoke from a third-rail fire.
Firefighters initially responded to the Gillette complex, where the smoke was first detected.
The T did not shut the power off to allow firefighters onto the tracks until 10:45 p.m., first to let a train in the tunnel between Broadway and South Station get to the South Station, then because for some reason workers couldn't shut the power remotely and had to do it by hand at the station.
Once that happened, firefighters quickly knocked the fire down, although the third rail continued to smolder.
Crowds of frustrated riders quickly grew outside Red Line stations as the T tried to assemble a convoy of shuttle buses for the rest of the night.
Firefighters finally left the station around midnight.
