Until the 1980s, Dieringhausen station, which is also in Gummersbach, was more important for the city as it had a rail workshop and was a railway junction. Gummersbach station only became more important with the closing of branch lines in the Oberbergische district and the associated loss of significance for Dieringhausen.
