Industrial development on the Wupper
The power of the river played a key role in the industrialization of the region. Traces of the cloth industry, which replaced the iron industry in the 19th century, can be discovered in Dahlerau. A small town developed around the textile company "Johann Wülfing & Sohn" with its own railroad station, bathing establishment, stores and workers' housing estates. A museum offers insights into the history of the former "textile town", where a large number of smaller companies have settled since the textile factory closed in 1996.
Railroad history in a deep sleep can be discovered at Dahlhausen railroad station: Old locomotives, wagons and construction vehicles are being restored here by an association that is also reviving the tracks of the disused Wuppertalbahn with bicycle trolleys. A few kilometers further on, the old tracks end since the dam for the Wupper reservoir was built in the 1980s. A regular bus service (line 671) runs from the edge of the dam back to the city center.
There are a total of five information boards along the way.
