SANFORD, Fla. -

The Florida Highway Patrol says a lack of communication contributed to the death of a conductor when a train derailed last year in central Florida.

Christopher Daniel Putfark of Deltona died in the Oct. 24 derailment. He was working as a spotter when one of several train cars carrying gravel tipped. He became trapped under one of the cars and crushed rock.

The Daytona Beach News-Journal reports that FHP investigators found that a lack of written documentation among three railroad companies about equipment on track contributed to Putfark's death. Investigators also found that visibility of lights and signals at the track was lacking.
