Omaha railroad Union Pacific is reminding July Fourth holiday travelers to be careful when crossing railroad tracks.

It can take more than a mile for a train to stop, and by the time a locomotive engineer sees a vehicle on a crossing, it is often too late to stop the train.

Union Pacific's police chief, Robert Morrison, says drivers should always expect a train at crossing and obey all railroad signals and gates.

The Federal Railroad Administration says there were 1,960 incidents at railroad crossings nationwide last year and 271 deaths.
