The line is operated for a special schedule when there are many passengers; it is basically the only transportation, particularly during Kurama Fire Festival held every October 22, when nearly all the cars are employed for operation; but still the passengers have to wait several hours before boarding at peak hour because the Kurama Line, with a limited track capacity, is a single track between Nikenchaya Station (Kyoto Prefecture) and stations to the north of Nikenchaya Station.
多客時は臨時ダイヤで運転されることがあり、特に毎年10月22日に行われる鞍馬の火祭においては事実上唯一の交通機関となり、ほぼ全ての車両をフル稼働させるぐらいの運転となるが、それでもピーク時には鞍馬線二軒茶屋駅(京都府)以北が単線で線路容量に制約がある関係もあって長蛇の列（乗車までに数時間の待ち時間）となる。
