For its entire length, the branch line follows the Erms river and it is now operated by the Erms-Neckar-Bahn Eisenbahninfrastruktur AG (ENAG).

The temporary closure of the railway began in the summer of 1971; the DB abandoned operations on the last section between the loading point of the URACA pump factory and Kunstmühle.

At the end of 1989, the sparse freight between the crossing loop at Dettingen Gsaidt and Bad Urach was finally abandoned.

In this context, three new stations were put into operation in the municipality of Dettingen an der Erms (Dettingen-Lehen, Dettingen-Freibad and Dettingen-Gsaidt).

The Tübingen regional council gave planning approval in February 2017, and construction began in October 2019.

The Erms Valley Railway has been fully integrated in the Verkehrsverbund Neckar-Alb-Donau (Naldo) transport association since 1 January 2002.
