"Operators of the historic Angels Flight railway in downtown Los Angeles had been using a tree branch to override a safety system in the months before a derailment in September"

"The operator then recognized a derailment had occurred and notified senior Angels Flight management of the derailment," the NTSB said.

But Angels Flight operators failed to notify the National Response Center or call 911 for assistance, according to the report. It was a bystander, the report said, who finally called the Fire Department to report the accident.

One passenger was helped off the derailed car and five were guided from the upper car by fire officials.
