LOUDONVILLE, OH -- A train derailment in Ashland County has several roads blocked off and has hazmat crews on scene.

Four of the derailed cars were carrying Zinc Oxide crude, while another was carrying odorless propane. Officials say it is "not a real concern" at this time, but it could become one as time progresses.
