Since 2019, there is a new geoportal of the Geopark "Porphyry Stone Kingdom in Saxony" at the Mügelner Kleinbahnhof.
The Mügeln station served as a central transshipment point especially for kaolin, which has been mined for over 100 years in the immediate vicinity of the city Mügeln and was continuously supported until 2001 by the Döllnitz trains. Today, the narrow-gauge railway operates only with diesel locomotives in daily passenger and student traffic. On selected weekends and public holidays as well as special events, a more than 100-year-old steam locomotive, the "Sächsische IV K", is used.
