NORTH LAS VEGAS, Nev. (AP) - North Las Vegas Fire Department officials say four freight train cars derailed but no injuries were reported.

Firefighters from throughout the Las Vegas Valley arrived just after 12:30 a.m. Saturday to the site near Donovan Way and Tropical Parkway to investigate the derailment and potential hazardous material spill.

The Las Vegas Sun reports one tank car carried alcohol, another contained a fatty acid, one boxcar had lumber and one boxcar was empty when they went off the rails.

A minor leak in one of the tank cars was discovered and contained. Officials say residents were never in danger.

Union Pacific Railroad has ordered equipment from Utah to remove the cars.

The cause of the derailment is under investigation.
