The Second Life of F.W.G. Platow (1973)

Friedrich Wilhelm Georg Platow worked for the railways his entire working life. He took up service at the small station of Luege 34 years ago. Now, the line is to be electrified and Platow, who cannot cope with the new technology, has to work on a secondary local line. Georg, his son, a railway worker as well, is to attend a training course, but Georg refuses to go. Then his father comes to a surprising and highly unusual decision. He pretends to be Georg Platow, making himself twenty years younger than he really is and registers for the course.
