White Train
During the height of the Cold War, the White Train worked out of the Pantex plant in the Texas panhandle. This train moved nuclear weapons from the plant where they were constructed to numerous sites to support the US nuclear program. From 1951 to 1987 The Department of Energy’s Office of Secure Transportation (OST) used the train to move the weapons by rail. The train became the focus for peace and anti-nuclear weapon activism in the west. While the train's color was changed numerous times to avoid notice, it continued to be referred to by its original color. After the last attempt to prosecute protesters who blocked the passage of the train failed, the Department of Energy began instead to move nuclear weapons by truck without public notice.
