As seen in the current timetable, train series 201 could operate directly between Kakogawa and Kyoto without any performance problems, but the actual quantity of available type 201cars at that time was not enough for the Keihanshin Local Line to accomplish this schedule, and since JNR was in a difficult position to increase the required type 201 cars, the Keihanshin Local Line was compelled to manage the existing cars by scrap and build methods.
現行のダイヤでもわかるように、201系であれば加古川～京都間を直通運行しても性能上問題はないのだが、そうするだけの編成数はなく、当時の状況では車両の増備もままならなかったことから、既存の車両だけで対応するにはスクラップ&ビルドもやむを得なかった。
