31 August, 1997: Union Pacific (UP) freight train Extra 8116 East struck the rear end of a Burlington Northern Santa Fe (BNSF) freight train near the BNSF classification yard at Barstow, California. All three lead locomotives, three trailing cars, and four cars of the preceding train were derailed. A small leak from one of the tank cars resulted in a cautionary restricted zone by the local emergency response. Once the product was identified and contained the restriction was removed.
