The San Bernardino train disaster kills four people. A week later an underground gasoline pipeline explodes killing two more people.

The San Bernardino train disaster, sometimes known as the Duffy Street incident, was a combination of two separate but related incidents that occurred in San Bernardino, California, United States: a runaway train derailment on May 12, 1989; and the subsequent failure on May 25, 1989, of the Calnev Pipeline, a petroleum pipeline adjacent to the tracks which was damaged by earth-moving equipment during the crash cleanup.
