OLIVIA, Minn. (AP) - Authorities are investigating the derailment of four cars on a Twin Cities and Western Railroad freight train in southwestern Minnesota.

Renville County Sheriff Scott Hable says his office received a call around 3:00 p.m. Friday that a train derailed a mile east of Olivia in Bird Island Township. Reports say that deputies found three empty tanker cars and a fully-loaded coal car left the tracks, none of which tipped over.

The derailment blocked one intersection and a private driveway.

Twin Cities and Western Railroad personnel were called to the scene to clear the blockage and repair the tracks. There were no reports of injuries.
