{{Unreferenced|date=August 2009}}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. Zwickau uses dual-gauge track, but that is not an essential feature of the model.
