From the article:
"The source, who spoke on condition of anonymity because of the ongoing investigation, said potential factors include the possibility that the PTC system in the northbound train’s engine was left in “switching mode,” which allows trains to pass red signals at reduced speed subject to approval having been granted by the train dispatcher overseeing the line."
In which case, how would this be a "PTC failure?"
