Gray County authorities investigating what caused a grain train to derail near Ensign Monday evening.
Jim Kramer, Gray County Sheriff, said six cars belonging to the Cimarron Valley Rail Road Company derailed around 5:45 p.m., just west of Ensign.
Kramer said the accident caused damage to the rails. He said the track is only used for grain transportation, and is not causing much of a backlog.
Kramer said he expects it will be a while before an exact cause is known. He expects cleanup to take a couple of weeks.
No one was injured in the accident.
