In addition to increases in the train speed, to further reduce the traveling time between major stations, efforts have also been made for shortening the stopping periods at stations and for maintaining high speeds between stations as long as possible, although the amount of time reduced with these measures is at a level counted in minutes.
また時速アップ以外にも、停車駅での停車時間の短縮や、停車駅間の速度を出来るだけ高速度で維持するなどして、僅かな分単位ながら主要駅間の時間短縮を図る工夫もされている。
