SAN LEANDRO (CBS SF) — A major medical emergency shut down the Bay Fair BART station in San Leandro for nearly an hour Wednesday afternoon when a person was hit by a train, according to transit officials.

The SFBARTalert Twitter account first posted about the incident at about 4 p.m. Wednesday.

A follow-up tweet a short time later clarified that a major medical emergency was underway and that trains would not be stopping at Bay Fair. Parallel bus service via AC Transit bus lines #97 and #10 is available.

Officials later confirmed a person was struck by a BART train. Officials said the collision appeared to be accidental and the victim was alive and on the way to get medical treatment.

At about 4:50 p.m., BART announced that the station had reopened.

The station closure may cause residual delays on the Dublin/Pleasanton and Warm Springs lines.
