The Wels–Passau railway—also called the Passauer Bahn in German—is a two-track, electrified main line railway mainly in Austria, which was originally owned and operated by the k.k. privilegierte Kaiserin Elisabeth-Bahn company. It runs from Wels in Upper Austria to Passau in Bavaria and is part of the core network of the Austrian Federal Railways.

Wels Hauptbahnhof, occasionally Wels Central Station or Wels central station is a railway station at Wels, which is the second largest city in the federal state of Upper Austria, in the north of Austria.
