The railway line and motorway in the valley

The Blombach is a 3.6 kilometer long stream in the Wuppertal district of Ronsdorf . The brook, which is a tributary of the Wupper , is also the namesake for the residential area Blombach-Lohsiepen and the Blombach valley.

topography

The stream has its source in the hamlet of Blombach, which emerged from a farmyard , south of an industrial park and then flows in an easterly direction. After around 350 meters, the brook continues to flow with pipes and crosses under the Wuppertal – Solingen railway line , over which the S-Bahn S7 “ Der Müngstener ” runs.

Then the Blombach turns to the north, undercrosses the federal motorway 1 (A 1) and after around 520 meters comes back to the surface. Here the brook had created a deeper valley known as the Blombachtal. The motorway follows this valley for around 1.6 kilometers, with the lanes in both directions running separately from each other. The central reservation of the autobahn, in which the Blombach runs, is around 70 meters wide. The valley, in which state road 58 (formerly federal road 51 ) now descends from the heights, is spanned by the Blombachtal bridge and turns east.

The Blombach crosses under the A1 again and leaves the Autobahn on the right-hand side. The 1.4 km long Schmalenhofer Bach joins it from the left . From here on, the stream is cased in sections to the mouth. It crosses under the L 58 again and then flows 195 meters above sea ​​level on the left side of the Wupper.

Landwehr

The Bergische Landwehr crossed the Blombach in three places . While the Barmer line crossed the valley at the level of the old schoolhouse, a branch of the Elberfelder Landwehr ran across the stream at the level of Werbsiepen and another branch at the level of the Blombachtal bridge.

Water engines

At the Blombach, like most of the streams in the Wupperviereck, the water was used to drive water wheels . The first water drive on the barrel was the copper hammer owned by Ehrenberg & Leuschner, which has been rolling copper since at least 1828. Nothing further is known about the dates of the construction and demolition of the hammer with two overshot waterwheels. It was followed by the Siepershammer (also called Mottenhammer or Paashammer ). The refining hammer had three overshot water wheels and was producing stainless steel as early as 1775. From 1837 the hammer served as an iron bar hammer and nickel silver roller.

300 meters further was the Tillmanns Hammer , a steel hammer that was driven in 1824 with three overshot water wheels. Another 100 meters further in 1824 a member of the Goldenberg family (see also Goldenbergshammer in Hückeswagen) operated a steel hammer, which was also called the Goldenbergshammer . He also had three overshot water wheels.

All of these structures no longer exist and only place names partially remind of them. The Blombach had only a little water, so that all hammers often had to stop working due to lack of water.
