The local vehicle travelling route includes a plurality of local vehicle travelling routes that are provided in parallel, and the local vehicles are configured to diverge and merge from one local vehicle travelling route to another local vehicle travelling route. The local vehicles transport articles between a load port and a buffer under control of a controller. The overhead travelling vehicles, under control of the controller, transfer articles to and from a load port or a buffer and transport articles between a load port or a buffer and a section other than the local vehicle travelling routes.
