As a result the society was criticised because funding was used to buy several German locomotives without any connexion to the railway history of Austria.
On the retirement of older locomotives from the ÖBB in the early 1990s the ÖGEG also obtained many electric and diesel traction units.
The railway museum in Ampflwang im Hausruckwald houses the society’s extensive steam loco collection.
In 2005 the Ampflwang railway museum acquired the turntable of the former Bahnbetriebswerk at Rosenheim as well as the traverser from the former SGP factory at Vienna-Simmering.
The railway museum was the venue for the Upper Austrian State Exhibition (Oberösterreichische Landesausstellung) in 2006 under the motto Kohle und Dampf (coal and steam).
