About 10:31 a.m., c.d.t., on September 18, 1978, Louisville and Nashville Railroad local freight train Extra 542 South collided head-on with L&N yard train No. 101 on the single main track within yard limits at Florence, Alabama. Both locomotive units and one car of each train were derailed. Three train crewmembers were killed. Since an LPG tank car was derailed and oil was spilled from ruptured locomotive fuel tanks, local officials evacuated about 1,000 persons from nearby residences. Total damage was estimated to be $462,500.
