S1·E5 Three Men Along the Rails -On the Rails-

As they make their way along an old railroad, Kino runs into a man who has been polishing the tracks for some fifty years. Stopping for a break, Kino entertains the man with a story of a land where the people no longer have to work, but choose to subject themselves to meaningless and stressful tasks anyway. It may seem foolish to the old man, but little does he realise that his own work is just as pointless, for, as Kino is about to discover, there are two more men working on the railroad, each undoing the work done by the others.
