At the end of a long service life, Streetcars do not necessarily end up on the scrap heap in Germany. Some are given a second home in other operations. Since 1990, 49 transport companies have handed over a total of 3,745 discarded streetcars to cities outside Germany. The fascinating complexity of this phenomenon was the motivation for Lukas Adolphi, Wladimir Sgibnev and Tonio Weicker to investigate the destinations and the further use of used streetcar vehicles from German companies in more detail. One result of these investigations are maps showing the manifold travel routes of individual vehicles.
