All done with their mock exams, the Himeno-Naoko-Mika trio spot
their pottery club advisor Mami by the train station and impulsively decide to tail her.
They pass through a forest, walk by a lake and finally reach a mountain.
Where exactly is Mami going?!
One of the pleasures 
of conductorless trains.
إحدى محاسن القطار بلا قاطع تذاكر
Das gibt’s nur in schaffnerlosen Zügen!
-Es un tren de un solo hombre.
-No los conocía.
-Es un tren de un solo hombre.
-No los conocía.
Ce brave homme gère tout.
Uno dei piaceri dei treni senza controllore.
As maravilhas do trem
sem condutor.
Радость поезда без кондуктора.
