A train operator reported seeing an adult male on the elevated track way, just north of the San Leandro Station. Trains were held out of the area while officers responded. Central allowed a nearby train to conduct a track inspection and the train operator was able to convince the male to board the train. The train was brought to the San Leandro Station where officers contacted the male and determined that he was in need of psychiatric evaluation. No one was injured, but trains were delayed approximately 17 minutes as a result of the incident. TSOC was notified.
