Abstract

A transportation facility includes a rail extending through an opening, a door to open and close the opening, and a restrictor. The rail includes a movable rail, a first fixed rail, and a second fixed rail. The movable rail is shiftable between a connected orientation in which the movable rail is disposed in the overlapping area to connect the first fixed rail to the second fixed rail, and a retracted orientation in which the movable rail is disposed outside of the overlapping area to disconnect the first fixed rail from the second fixed rail. The restrictor is in a normal orientation with the movable rail in the connected orientation where the restrictor does not restrict travel of a transport vehicle, and shifts to a protruding orientation in response to the movable rail being shifted from the connected orientation to the retracted orientation where the restrictor restricts travel of the transport vehicle.
