Free cutting, clearing and securing of the rock embankment Calw ZOB.

The district of Calw took over the Weil der Stadt — Calw section of the “Württemberg Black Forest Railway” (line 4810) from Deutsche Bahn AG on January 1, 1994 and has been aiming for a new traffic intake as a “Hermann Hesse Railway” ever since.

In addition to basic track construction, the renovation and repair of various structures on the route is required before a new start of traffic is resumed. Securing the embankment on the line in the area of the future Calw ZOB station as well as accompanying clearance work is part of the present call for tenders.
