Oct 14 (Reuters) - Railroad operator BNSF said on

Tuesday it had received a report of a train derailment in

Scotland, South Dakota, that has disrupted operations on its

main track.

The derailed train was carrying grains, BNSF said in an

e-mail to Reuters.

The Berkshire Hathaway ( BRK/A )-owned railroad said there

were no reported injuries to the crew and there was no hazmat

involved.

"A team is on site working to clear the incident as quickly

and safely as possible. An estimated time for reopening the

track has not yet been determined," the company said, adding the

cause of the incident is under investigation.
