(04-11) 21:11 PDT HAYWARD -- Amtrak service to Sacramento resumed Thursday night after a two-hour delay when a train killed a juvenile near Hayward, according to Amtrak.

Nearly an hour after the Sacramento-bound train left San Jose at 5:50 p.m., it struck and killed a juvenile who was believed to be trespassing on Union Pacific Railroad property north of the train station in Hayward, Amtrak spokesman Marc Magliarasaid.

Magliara said the train may have hit one other person.

None of the 133 passengers or five crew members onboard the train were injured, Magliara said.

As of 8:30 p.m. the train was again running, he said.

"These incidents are tragic," Magliara said, "but they're always avoidable if people would simply not trespass."
