In the boiler house of the Mh.6 railroad club in Ober-Grafendorf, visitors can discover historic railroad vehicles, locomotives and freight wagons from the Mariazell Railway.
The highlight of the listed workshop is a nostalgic Mh.6 steam locomotive, which still runs on the Mariazell Railway between St. Pölten and Mariazell on a few days a year. The living narrow-gauge museum in the Ober-Grafendorf boiler house can be visited at any time on working days.
