Wrecked boxcars lie scattered across the tracks at the Southern Pacific rail yard in Roseville, California, following the catastrophic explosion of April 28, 1973. A train loaded with aerial bombs and munitions destined for U.S. forces in Vietnam ignited and detonated in a series of blasts, destroying rail cars and structures across the yard. Despite the scale of destruction, the disaster caused no fatalities, though it remains one of the most dramatic domestic incidents connected to the logistics of the Vietnam War. Project: 218336
