Automated Terminal Trucks (ATTs) operate at the terminal. These vehicles transport internal containers between the rail terminal and the stacks.
Each ATT is equipped with a light signal: ● No light or blue light: the ATT can start driving. ATT's give an audible signal and briefly display their flashing lights when they start driving or reversing. ● Red light: the ATT has a malfunction.
