A transport system in which overhead traveling vehicles and a local carriage are both configured to transfer articles to and from the same transfer destination, the transport system comprising: a track for the overhead traveling vehicles ; a track for the local carriage that is located directly below the track for the overhead traveling vehicles ; a transfer destination located directly below both the track for the overhead traveling vehicles and the track for the local carriage ; overhead traveling vehicles configured to travel on the track for the overhead traveling vehicles and including an elevating platform configured to move vertically while supporting an article ; and a local carriage configured to travel on the track for the local carriage and including an elevating platform configured to move vertically while supporting an article ; and a buffer provided in a location that is not directly below the track for the local carriage , the buffer being connected to the track for the local carriage and being configured to deliver and receive the articles to and from the local carriage , wherein the buffer includes: a plurality of cells configured to accommodate an article ; a transport in/out cell for the overhead traveling vehicles to transport articles to and from the transport in/out cell being provided below the track for the overhead traveling vehicles ; and a transport apparatus configured to transport an article between the cells , characterized in that the transport in/out cell is the uppermost cell in the buffer , the buffer has plural cells for accommodating the article vertically below the transport in/out cell , the track for the local carriage extends to one of the cells different from the transport in/out cell . a track for the overhead traveling vehicles ; a track for the local carriage that is located directly below the track for the overhead traveling vehicles ; a transfer destination located directly below both the track for the overhead traveling vehicles and the track for the local carriage ; overhead traveling vehicles configured to travel on the track for the overhead traveling vehicles and including an elevating platform configured to move vertically while supporting an article ; and a local carriage configured to travel on the track for the local carriage and including an elevating platform configured to move vertically while supporting an article ; and a buffer provided in a location that is not directly below the track for the local carriage , the buffer being connected to the track for the local carriage and being configured to deliver and receive the articles to and from the local carriage , wherein the buffer includes: a plurality of cells configured to accommodate an article ; a transport in/out cell for the overhead traveling vehicles to transport articles to and from the transport in/out cell being provided below the track for the overhead traveling vehicles ; and a transport apparatus configured to transport an article between the cells , a plurality of cells configured to accommodate an article ; a transport in/out cell for the overhead traveling vehicles to transport articles to and from the transport in/out cell being provided below the track for the overhead traveling vehicles ; and a transport apparatus configured to transport an article between the cells , characterized in that the transport in/out cell is the uppermost cell in the buffer , the buffer has plural cells for accommodating the article vertically below the transport in/out cell , the track for the local carriage extends to one of the cells different from the transport in/out cell . <EOS>
