The Grafing–Wasserburg railway is a 29.1 km long, wholly single-track branch line in Upper Bavaria. It was partly built between 1899 and 1905. It is also called the Filzenexpress, which refers to the former raised bog (known in Bavarian as Filz)) it crosses in the Ebrach valley. The rail infrastructure of the Grafing–Ebersberg section is owned and maintained by DB Netz. The following section to Wasserburg is owned by SüdostBayernBahn. The town of Wasserburg owns the infrastructure from Wasserburg station to Wasserburg town.
