From Hinwil to Bauma the line has been preserved by the Dampfbahn-Verein Zürcher Oberland (DVZO) and sees heritage railway services.

The line provided a link between Uerikon, on the shores of Lake Zurich, and the Zürcher Oberland, including the town of Bäretswil where he owned a textile mill.

In 1946 it was decided the UeBB, together with the Uster-Oetwil-Bahn and Wetzikon-Meilen-Bahn lines, was to be converted to bus operation by the newly formed Verkehrsbetriebe Zürichsee und Oberland (VZO).

The section from Hinwil to Bäretswil remained in Swiss Federal Railway ownership until 2018, when it was sold to the Sursee-Triengen-Bahn.

The Sursee-Triengen-Bahn leased the Bäretswil to Bauma section from the DVZO in 2019, giving it complete control of the infrastructure.
