At the outset these were express bus routes with three round trips each, but they've subsequently enhanced their services to five round trips in the case of the Osaka Namba Route, six round trips in the Kobe Sannomiya Route, and a total of 13 round trips including the Osaka Umeda Route, with a plan for further increased frequency; thus they're consolidating their strong position.
当初はともに3往復で運行していた高速バス路線であったが、現在は大阪なんば線が5往復、神戸三宮線が6往復にまで成長、従来の大阪梅田線を含めると計13復にまで充実させてきており、更に増発を検討中とのことで、確固たる地位を確立しつつある。
