A train derailment in southeastern Minnesota near Reno could be related to the failure of a wooden railroad bridge.

Department of Public Safety spokesman Doug Neville says it's not clear if the privately owned bridge collapsed under the train, or if derailed cars took it out.

The derailed train and the bridge are owned by the Iowa, Chicago & Eastern Railroad, Neville said.

An IC&E spokesman says 27 cars derailed Tuesday morning. There were no injuries. The company says the cause of the derailment is under investigation.

The derailment caused an ethanol spill on Highway 26 near Reno, which is near the Iowa border. The highway is expected to stay closed until at least Wednesday afternoon.
