Railroad officials are continuing their investigation into what caused a five-car derailment on Norfolk Southern Railroad in Augusta County, Virginia on Tuesday afternoon.

Five empty rail cars derailed early Tuesday afternoon, halting the progress of a northbound Norfolk Southern freight train and blocking traffic on Greenville School Road near Virginia Route 608.

Police reported no injuries or adjacent property damage along Pine Run.

The Norfolk Southern train with three locomotives and 99 cars carrying various types of freight was traveling from Roanoke to Shenandoah when five gondolas left the track.

Norfolk Southern spokesman Robin Chapman said the cause of the wreck was under investigation.
