EJ&E Flat Car 4-pk 

Developed at the beginning of the Cold War in the early 1950s as a tactical nuclear weapon, the M65 Atomic Cannon, nicknamed “Atomic Annie,” was 86 tons, 85 feet long, and 10 feet wide. It fired a 15 kiloton nuclear warhead at 2,500 feet per second. Around 20 cannons were produced and deployed in West Germany, South Korea, and Okinawa. The canon was transported  on a 50’ flatcar with Bettendorf trucks to its destination and then moved into position by integrated push/pull tractors.
