Thörl is a market town at the foot of the Hochschwab in the Styrian district of Bruck-Mürzzuschlag.

As of 1 January 2015 the formerly independent municipalities Sankt Ilgen and Etmißl were incorporated into Thörl.

In its further course it leads to Sankt Pölten, the capital of the neighbouring state of Lower Austria.

In 1893, the Thörlerbahn, a narrow gauge railway with a track gauge of 760 mm, which linked the area with Kapfenberg and the Austrian Southern Railway (Südbahn), was opened.

But when a bank failure bankrupted the local iron industry, the operator of the railway, Steiermärkische Landesbahnen, lost their largest (and actually the only) freight customer.
