Be careful! The AEC is ready for work on your layout to carefully move all hazardous radioactive materials to safe destinations. The specially decorated Atomic Energy Commission (AEC) burro crane pulls two AEC gondolas loaded with radioactive containers, raw steel material, and nuclear isotopic waste from a nearby nuclear reactor site to a disposal facility further down the tracks. As you can see by the glow-in-the-dark decoration on the cars, these radioactive loads must be handled carefully!
