Embarcadero Station is shut down this morning as rescue workers attempt to free a person trapped under a train. According to BART, trains are skipping the station "due to a major medical emergency."

The Chronicle reports that as of 10:50 a.m. the unnamed person was still alive, and writes that BART spokesperson Taylor Huckaby expects major delays to develop. According to the paper, trains are presently single-tracking through the station.

At this time it is not known how the person ended up under the train, or whether it was an East Bay or SFO bound train. We have reached out to BART, and will update this post with more information as it becomes available.

Update: Huckaby confirmed to SFist that as of 11:41 a.m. the person has been removed from the track, however no further details about the person, or their health, have been released. Embarcadero Station remains closed.

Second Update: Trains have resumed stopping at Embarcadero Station, although residual delays are expected. Miraculously, the rescued man is reportedly alive and talking.

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
