As of about 2000, the ÖBB was considering selling or abandoning the main line between St. Pölten and Mariazell. In the autumn of 2003, a plan was drawn up to convert the line between St. Pölten and Kirchberg an der Pielach to standard gauge, as this stretch was considered important for commuters and school children. However neither plan was carried out, and the ÖBB continued to provide narrow gauge service on the main line up to the transfer of the line in 2010.
