The report is out and it says it was human error that led to an accident that killed two railroad workers near Edgemont in January of last year.
The National Transportation Safety Board released its report Thursday on the accident that killed 35-year old Richard Lessert and 58-year old Douglas Schmitz.
A Burlington Northern Santa Fe train traveling at 35 miles per hour struck and killed two of three workers who were clearing snow and ice from a track switch.
One of the workers was the designated lookout and the NTSB says the sight distance at the switch was inadequate for safely using a train approach warning method with only one lookout.
Investigators also found the lookout did not devote his full attention to detecting approaching trains and was not given the necessary equipment.
BNSF says it will review the report and recommendations.
