On 12 May 1989, a 69-car freight train goes out of control while descending from California's Cajon Pass. It derails in a residential neighbourhood of San Bernardino after reaching speeds in excess of 100 miles per hour (160 km/h). Two residents and two train crew members are killed in the initial crash. More than a week later, an underground gasoline pipeline, damaged by earth-moving equipment during the post-crash clean-up, ruptures and sparks a fire that kills another two people.
