However, the train schedule is very unbalanced; because a lot of single-track regions still remain, while there are 3 to 4 trains per hour, excluding the limited express trains, there are time slots during which people have to wait more than thirty minutes for trains, not only during the day but also during the evening rush hours.
しかし現在でも単線区間が多く残ることなどから、特急列車を除くと、毎時3～4本の運転がありながら、昼間のみならず夕方のラッシュ時にさえ30分強もの間隔で列車が運転されている時間帯があり、不均衡なダイヤとなっている。
