Owing to the scarce population along the line, this line could only concentrate its efforts on inter-urban transportation and focus on operating trains at high speeds, such as the super express that connected Tenjinbashi and Omiya in 34 minutes.
沿線の人口が少ないため同線は都市間輸送に注力するしかなく、天神橋～大宮間を34分で結ぶ超特急などといった高速運転を行う列車を集中的に走らせることにした。
