Together with the through operation to the Keihanna Line, the two lines have a unified nickname "Yumehanna" (ゆめはんな).
On 1 July 2005, Osaka City bought the Technoport Line (テクノポート線) from Cosmosquare to Osakakō of its subsidiary Osaka Port Transport System Co., Ltd. (大阪港トランスポートシステム), reducing fare to increase traffic. The section operationally became a part of the Chūō Line, but is however still owned by OTS.
The Chūō Line is the only line to connect to all other subway lines operated by the Osaka Metro, including the Nankō Port Town Line.
