The Museumsbahn runs from a small station at Steyr-Lokalbahnhof up the Steyr valley to Grünburg on summer Sundays and public holidays. The line winds along the river for 17 km, crossing several iron-truss bridges and stopping at country halts. The journey takes about an hour each way.
The Grünburg end has a small museum of old rolling stock and a beer garden. Tickets are sold on board; check the timetable on the operator's site before going as services are limited.
