Six years old Dirk wants to be a train driver, just like his grandfather. He is seriously impressed with all of the exciting rides through the desert and the mountains, of which the old man told. If you want to bulk, you must start small. So Dirk goes every day to the railway embankment and “monitored” the track. But his friends doubt that his grandpa all of these adventures has also experienced really and that Dirk is riding on a real locomotive. He is unsure of. However, the concerns dissipate quickly, as he goes with the grandfather on a long journey.

Der kleine Dirk möchte wie sein Großvater Lokführer werden. Die anderen Kinder bezweifeln, ob der alte Mann all die Abenteuer, von denen er erzählt, wirklich erlebt hat. Dirk wird dadurch unsicher, aber als er sich mit dem Großvater auf große Fahrt begibt, sind die Zweifel rasch zerstreut.
