The Journey to the Utopian Town

A few years ago my brother brought a book of short German stories; we both remember a simple but meaningful story from that book.
The theme of the story is similar to what Thomas More talks in his book Utopia. A man decides to leave his home to experience living in a utopian town he had heard about. He tries to convince his wife and they together decide to join the life of immigrants. Finally, they take a train to their destination. In one of the stations in the way the train gives the passengers a few minutes to rest and the couple decide to walk in the area near the train station. Returning from their walking they find out that the train has already gone. They start to find a temporary place to live in the village which is actually smaller than their home town and wait till the next train will come. Many days pass and the train does not come or if it comes the wife finds an excuse to resist going. So, the man decides to leave alone. While he is leaving the woman tells her that she’s pregnant. Many years pass and now they have a new life in the village in their way to Utopia.
Recently, I understood that Iran is in the process of a TV play of this simply philosophic story.
