The Gunn High School student who died on the Caltrain tracks Monday night has been identified as William Dickens, 16, a junior at the school.
"We at school are all struggling to come to terms with this incomprehensible loss," Gunn Principal Noreen Likins said in a brief message to Gunn families.
Grief counselors were on hand for Gunn students Tuesday following the fourth Caltrain death of a member of the school community in six months.
Dickens, who has a 10th grade sister at Gunn, was a resident of the Stanford campus and had been a member of the water polo team since his freshman year. He reportedly quit the team in early October.
The death occurred about 10:50 p.m. Monday on the southbound tracks about 50 yards south of West Meadow Drive, Caltrain officials said.
Dickens had attended Nixon Elementary School and Terman Middle School, Likins said.
Gunn school psychologist George Green, as well as staff from other schools, the grief counseling agency KARA and Adolescent Counseling Services, were on campus Tuesday.
"Please encourage your students to seek assistance if they need or want it," Likins said in her message to the Gunn community.
The West Meadow crossing has been the site of several suicides and apparent suicide attempts since spring, prompting an outpouring of community concern and programs within schools and community to address support for teens.
