The driver advisory system focuses cruising driving operation for a freight railway by maintaining the planned time of passage station. The driver advisory system proposes a recommended driving operation for each passage station.First, we discuss an energy saving driving method called cruising driving for freight railways considering the running resistance and motor efficiency. As a result of an energy calculation, we found that is necessary to use constant-speed and saw-toothed driving operations properly depending on speed and load characteristics, including hauling mass and gradient of running line. Then, we have developed a driving operation assignment method using the speed estimation, which switches between constant-speed and saw-toothed driving operations depending on speed and load characteristics. Finally, we present a trial result focusing on energy consumption. We confirm the energy-saving effect comparing the energy consumption with or without the developed driver advisory system.本誌: IEEJ Journal of Industry Applications Vol.13 No.6 （2024）本誌掲載ページ: 754-760 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/13/6/13_23002413/_article/-char/ja/
