At the same time the Royal Württemberg State Railways cleared the section from Schiltach to Freudenstadt Hbf for traffic.

The line diverges from the Black Forest Railway at Hausach and runs east along the Kinzig River to Schiltach, for a total length of 14.2 kilometres (8.8 mi).

At Schiltach station a railbus rake and the old railway bridge over the Kinzig recalls this branch that, today, has been full dismantled.

In Schramberg there is still an overgrown buffer stop and the former station tavern, which is used today as a clubhouse for the Black Riders.

The majority of trains run on past Offenburg to Bad Griesbach, the terminus of the Rench Valley Railway.
