The Zwickau model is an inversion of the Karlsruhe model, with diesel main-line trains extended through city streets on tram track. It is so called because the German city of Zwickau was the first to introduce it, with bergen following.
Zwickau uses dual-gauge track, but that is not an essential feature of the model.
Famous quotes containing the word model:
“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
—Erik H. Erikson (20th century)
