The story takes place in a world where the environment has been destroyed by pollution and wars, and the only way to survive is to adapt to new technologies and find new ways of living. The book begins with the introduction of the main character, a young man named Max, who is part of a group of engineers who have developed a revolutionary new train system that runs on electricity generated by the passengers themselves. The train system is called "Modelleisenbahner" and it quickly becomes popular among the population as a clean and efficient mode of transportation. However, as the story progresses, Max realizes that the technology they have created is not just a means of transportation, but also a symbol of hope and unity in a world torn apart by conflict and environmental degradation. As the story unfolds, Max and his team face challenges from both within and outside their own ranks, as they struggle to maintain control over the technology and keep it out of the hands of those who would use it for destructive purposes. Along the way, Max must confront his own personal demons and learn to trust his colleagues in order to save humanity from extinction.
