CUT BANK, Mont. — BNSF Railway crews are working to re-open the main line across Montana after a westbound grain train derailed and closed the line Thursday near Cut Bank.

BNSF representative Ross Lane tells Trains News Wire that 12 cars on the westbound train derailed at approximately 1:23 p.m. Mountain time on Thursday. No one was injured in the derailment and no hazardous materials were spilled.

Lane said it was unclear when the main line would be reopened.

Both eastbound and westbound Amtrak Empire Builders were impacted by the derailment and passengers were being transported around the derailment late Thursday.
