A report released Tuesday by the Florida Highway Patrol finds, "there was a lack of communication and documentation between all companies involved," in activity at a railway construction site near Airport Boulevard and State Road 46 in Sanford, when a train derailed in October 2013.
A 36-year-old conductor Christopher Putfark was killed in the crash, during which four cars derailed.
According to the report, a piece of railway equipment called a derailer was placed on the tracks just five minutes before the accident. Derailers are meant to stop trains from passing through areas where railway work is being done.
The investigator found that there was a lack of communication about the placement of the derailer and the movement of the train.
The FHP is charged with investigating industrial accidents. The derailment is considered an industrial accident.
