The United States Department of Energy Nuclear Weapons Transport Train, known as the White Train, was used to transport nuclear weapons for most of the Cold War.
From 1951 to 1987, the Department of Energy's Office of Secure Transportation (OST) used the train to move the weapons from the Pantex plant in the Texas panhandle, where they had been constructed.
[1] The train, which was armored and carried an array of defensive armament, became the focus for peace and anti-nuclear weapon activism in the west.
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.
