Suicide by train is a big problem in the SF Bay Area. Cal Train which operates the commuter line between San Francisco and San Jose (about 60 miles) hits and kills about one person per month. Many are teenagers committing suicide. A single high school in Palo Alto had several kids commit suicide by train last year. This is just one sad aspect of our modern life.
