The Transportation Operations Series, numbered 2150, covers federal positions whose work is the operation of transportation systems and the services they provide. It can concern rail transportation, motor transportation, air transportation, or water transportation. A position may involve planning how a system or service will run, directing it once it is in use, or performing the operating work.
Jobs in this series sit at different levels of responsibility. Some people perform the operating work, some supervise it, and some administer it. The series is written to cover all of the positions whose duties fall into that work.
Terminal facilities come into this series too. One position can hold responsibility for operating a transportation service and for operating terminal facilities at the same time.
