14:32 キハ40の6両はかつての学園都市線を彷彿、非常に長く感じられます Diesel series 40 6-cars are reminiscent of the old Gakuen-Toshi Line, and it feels very long. 最高速度を変えず、所要時分の短縮は加速性能の向上や駅の削減で実現したと思います I believe that the reduction in travel time without changing the maximum speed was achieved by improving acceleration performance and reducing the number of stations.
