SAN LEANDRO -- A young woman crossing railroad tracks on a busy street was hit by an Amtrak train and killed Monday evening -- apparently while wearing headphones that may have prevented her from hearing the train or a bystander who tried to warn her, police said.

Shortly before 6 p.m. San Leandro were called to the intersection of Hesperian Boulevard and Springlake Drive. Officers found a southbound Amtrak passenger train stopped on the tracks a few hundred yards south of the intersection and a young woman about 50 yards south of the intersection.

The victim was pronounced dead at the scene; authorities did not immediately identify her, but her family told television station ABC7 that she was Brittney Silva, 18, of San Leandro. Police called the death an accident.

No other injuries were reported. An Amtrak spokeswoman was not immediately available Monday night.

Witnesses told police the teen was walking south on Hesperian Boulevard and wearing earbud-style headphones. As the train approached the intersection, one of the witnesses yelled to her about the approaching train, but she did not respond, police said.

Police said the railroad crossing arms were functioning properly at the time of the collision.

Less than a month ago, on April 29, Silva and her mother witnessed the aftermath of an explosion at a homeless camp off Hesperian Boulevard possibly sparked by a couple using butane to make hash oil in a tent. One burn victim with skin hanging off her face and arms banged on the Silva family's door and then jumped into a bathtub. A man who was also burned used an outside garden hose to wash off.
