It also placed an emphasis on transportation capacity by constructing its line with a track gradient of less than 10 per millimeter except one segment (at Senohachi in Hiroshima Prefecture at 22.5 per millimeter), a curve radius of more than 300 meters.
また輸送力を重視し線路は一区間（広島県内の瀬野八の22.5パーミル）除き、勾配は10パーミリ以下曲線は半径300m以上で建設された。
