LOS ANGELES — Federal investigators said Sunday that a collision warning system they have long called for could have prevented the head-on crash here last week between a commuter train and a freight train that killed 25 people.

Investigators continued to work Sunday morning at the scene of a California train crash that killed 25 people late last week.
The system, known as positive train control and in use sporadically in parts of the country, “would have prevented this accident,” said Kitty Higgins, a member of the National Transportation Safety Board, which is investigating the accident.
The board has long pressed for such a system on all trains, but the industry has resisted on the grounds that it is expensive and in some cases not reliable.
But Ms. Higgins, speaking at a news conference here Sunday evening, said she made her assessment after reviewing the preliminary evidence of the investigation, which she said showed that the commuter train bypassed a red signal and barreled through a switch, bending it “like a banana.”
A collision avoidance system, she said, would have automatically slowed the trains, perhaps stopping them in time before they met in the deadliest train accident in the country in 15 years. More than 130 people were injured, and workers on Sunday were still clearing the wreckage.
