OMAHA, Neb. (AP) — As a blast of wintry weather hits the Midwest, Union Pacific Railroad is reminding motorists to use caution at rail crossings during slick, cold-weather conditions.

The Omaha-based railroad says that with blowing and drifting snow, it could be difficult for motorists to see where crossing surfaces are located. When possible, motorists should use overpasses or underpasses to get to the other sides of railroad tracks.

The railroad also warns that those driving too fast for slick conditions could slide into the path or the side of a moving train at a crossing. It can take a mile or more for a moving train to come to a stop.
