Bad Wimpfen
In the 1860s the city's train tracks were extended to Heidelberg via Bad Wimpfen, to Würzburg via Osterburken, and to Crailsheim (and later on to Nuremberg) via Schwäbisch Hall. In 1880, the Kraichgau line was completed and created an important connection towards Karlsruhe, and by the end of the 19th century, Heilbronn had become an important hub, second in Wuerttemburg to Stuttgart in industrial output.
