The Bavarian Forest Railway (Bayerische Waldbahn often just called the Waldbahn) (KBS 905) links the heart of the Bavarian Forest around Regen and Zwiesel to Plattling and the Danube valley on one side, and the Czech Republic through Bayerisch Eisenstein on the other. In the Danube valley it forms a junction with the Nuremberg-Regensburg-Passau long distance railway (KBS 880) and, to the south, regional lines to Landshut and Munich (KBS 931).
