Union Pacific spokesman Mark Davis tells KNZA-FM (http://bit.ly/1tINaSF ) no one was injured when the cars were toppled around 12:05 a.m. Wednesday in the Brown County community of Willis.

The National Weather Service confirmed the small town was hit by an EF-1 tornado, with winds up to 100 mph. The 134-car coal train was bound from Wyoming to Arkansas and stopped because of the extreme weather.

Davis said a tornado warning had been issued, and the train’s emergency technology alerted the crew that wind gusts were high enough to put the cars at risk of derailing.

Davis also said the track escaped damage because the wind simply pushed the 52 cars onto their sides.
