FAIRLESS HILLS, Pa. -- An Amtrak Acela train traveling 100 mph rounded a curve and killed three teen-agers who were walking on the railroad tracks with their backs to the train, authorities said Sunday.
None of the roughly 300 passengers was hurt.
The three victims were among a group of five teen-agers trespassing in the industrial area in suburban Phil/-adelphia, police said. Access to the rail tracks had been blocked by a fence.
"We don't know if they heard the train or not," Falls Township acting Police Chief Neil Harkins said. "The train engineer saw them and he tried to stop and was unable to do so and they were struck."
Harkins said the victims were three males, aged 14, 15 and 19. A 14-year-old girl and a 14-year-old boy got away before the train reached the group.
Police did not immediately identify any of the victims, but said two were from Morrisville, Pa. Authorities were contacting family members Sunday night, but said the survivors only knew the 19-year-old by his first name.
