The Traunseebahn is a historic railway in Austria, running from Vorchdorf to Gmunden.
The railway was built in 1912; it connected Gmunden - then a successful spa resort - to the agricultural area around Vorchdorf. Early investment in electrification allowed the railway to remain viable where a steam railway would not.
The terminus was moved from Traundorf to Seebahnhof in 1990. Today the historic railway carries a mix of commuter and tourist traffic. It is still operated by Stern und Hafferl Verkehr.
There are plans to extend the Traunseebahn so that it terminates closer to the centre of Gmunden, at Klosterplatz. From there it might be possible to extend the line further, to Gmunden's ÖBB station.
