Texas authorities say a dozen train cars have derailed near Valley Mills, including five tanker cars carrying methanol.

Department of Public Safety spokesman Trooper D.L. Wilson says no injuries or fires have been reported from the Saturday evening accident. He says one or two of the methanol-hauling tanks have small leaks.

Wilson says about 10 nearby homes were evacuated as a precaution. Residents were allowed to return around 9 p.m.

Wilson says it's unclear what caused the derailment, but says heavy rain has been falling in the area. He says the weather was making it difficult for vehicles to get to the scene to unload material from the derailed cars, which also include seven flatbeds carrying oil-well pipes.

He says a hazardous materials crew is on the scene.
