A man who was injured underneath a westbound BART train at Montgomery Station Wednesday morning led to significant systemwide delays — including a significant backup in West Oakland for SF-bound riders.

The incident happened around 10:10 a.m., and BART put out an alert at 10:23 saying that Montgomery Station was closed and that Muni was providing mutual aid for commuters. KPIX/CBS SF reports that the train involved was a Millbrae train out of Richmond.

The station reopened and trains were reportedly operating through it as of 10:49 a.m., as the Chronicle reports, but residual delays lasted well past noon.  ABC 7 had helicopter footage of the crowded platform at West Oakland in the hours after the incident.

Responders reportedly removed the man from the tracks and he was transported to the hospital at 10:50 a.m.

10-minute delays in the system were still being reported at 1 p.m.

No further details about the incident were available.
