The single-track line ran 2.6 km (1.6 mi), from the railway station (called the Rudolfsbahnhof at the time) to Rathausplatz (Town Hall Square), with nine stops.

[3]: 35, 193 In 1975 the section of the line from Franz-Josef-Platz to Rathausplatz was closed to make more space for road traffic,[9][10] leaving the tramway only 2.3 km (1.4 mi) long.

This involved building 700 m of new track, including rebuilding a road bridge over the Traun, and replacing the rolling stock on both lines with new low-floor trams.

[13] Construction of a new double-track line from Franz-Josef-Platz to Klosterplatz (via Rathausplatz, the original terminus) began in 2015, followed by reconstruction of the Traun bridge in 2017.

[4] The first test trains ran over the new track in August 2018 and the Traunseetram from Gmunden to Vorchdorf began operation on 1 September 2018.
