A BNSF Railway spokesman says the company is investigating the cause of a coal train derailment in which 13 cars came off the tracks in southeastern Montana.
BNSF spokesman Matt Jones said the loaded train originated at the Decker Mine in Bighorn County. It was en route to Superior, Wisconsin, when the cars derailed near Worden at about 7:45 p.m. Thursday.
No one was injured.
Crews were still on the scene Friday morning.
Jones says it's uncertain when the track will re-open.
