Forest railway
The Deggendorf–Kalteneck railway linked the railway line running through the Bavarian Forest from Plattling via Zwiesel to Bayerisch Eisenstein with the Ilz Valley railway ("Ilztalbahn") from Passau via Waldkirchen to Freyung. In keeping with the naming of the Bavarian Forest railway or "Waldbahn" from Plattling to Bayerisch Eisenstein, it was called the "Vorwaldbahn" (lit: pre-Forest railway).
