In the past, there was a branch line running between Yao Sugimotocho Stations, that connected the Kansai Main Line with the Hanwa Line and was commonly called the "Hanwa Freight Line" or "Hanwa Connecting Line," and JR West set passenger business kilometers of 11.3km (trains ran on the main line between Yao and Kyuhoji and this line actually diverged at the point between Kyuhoji and Kami).
かつて関西本線と阪和線を結ぶ連絡線として通称「阪和貨物線」「阪和連絡線」と呼ばれる八尾駅-杉本町駅間の支線があり、JR西日本の旅客営業キロ11.3kmが設定されていた（八尾-久宝寺間は本線と重複で実際は久宝寺-加美間から分岐）。
