Once open, the rush of passengers was so great that for a time, the railway did not even bother with advertising. Among the various kinds of freight carried on the railway were agricultural products, ores from local mines, and wood from the heavily forested mountain region. Wood remained the most important kind of goods on the Mariazell Railway right up until freight operations were discontinued. As early as 1909, standard-gauge goods wagons were being transported along the Mariazellerbahn on transporter wagons, insofar as the railway's narrow loading gauge would allow it.
