SAN LORENZO -- A man was struck and killed by a train near San Lorenzo High School Wednesday afternoon, about one month after a student was stuck and killed in the same area, police said.

The name and age of the man, who was on the tracks about 2:30 p.m., was not released pending notification of his family, said a spokesman from the Alameda County Coroner's office. An official at the school said the person killed Wednesday was not a student.

The incident remains under investigation and Alameda County Sheriff's office spokesman Sgt. J.D. Nelson said it has not yet been determined if the man was wandering on the tracks or if he had committed suicide.

San Lorenzo Unified School District Superintendent Dennis Byas alerted parents and guardians of the fatality, which drew police and helicopters to the area and closed Lewelling Boulevard as school was ending Wednesday.

School officials planned to have mental health workers available on Thursday for students who need to talk about the incident.

On April 11, Austin Price, a popular 15-year-old sophomore, and two other boys were playing a game of "chicken" on their bikes, racing a train and trying to cross in front of it, along the tracks near Lewelling Boulevard and Via Granada, when Price was hit and killed.

The death heavily impacted San Lorenzo High students, and school officials said in an email Wednesday that those who knew Price may be most impacted by the train fatality Wednesday.

The Amtrak Capitol Corridor train was headed from Sacramento to San Jose when the man was hit.

No one else was injured.

The incident and a crew change on board trains in both directions and caused trains to bypass the Hayward station. Passengers were bused to the Fremont station, an Amtrak spokeswoman said.
