Explosion in Roseville, California
The Roseville Yard Disaster was an accidental explosion and fire that occurred on April 28, 1973, in the United States at a major Southern Pacific rail yard in the city of Roseville, California. The shipment of munitions bound for the Vietnam War originated at the Hawthorne Naval Ammunition Depot in Hawthorne, Nevada. Explosions continued for a number of hours and the loudest could be heard as far as away. There were no fatalities, although 48 people were injured.
Subsequent investigation pointed to a small fire in a boxcar caused by overheated brakes. The U.S. military-owned boxcar was part of a train of military boxcars carrying high explosive aircraft ammunition that had just arrived in the yard after descending from the Sierra Nevada into the Roseville Yard. The train had been switched to a Southern Pacific line in Sparks, Nevada, before descending from Donner Summit.
According to the California Governor's Office of Emergency Service, "On April 28, 1973, in the Southern Pacific Railroad yard near the Northern California community of Roseville, a bomb detonated in one of the boxcars creating massive explosions, huge plumes of smoke in the air, destroyed buildings and rail sections and dug huge craters in the ground. Over a period of approximately 32 hours, 18 boxcars exploded in succession. The railroad yard was essentially destroyed."
As of 2024, bombs and fragments believed to be from the incident were still being found in the area.
