Munich–Salzburg railway is a major intercity and regional rail corridor linking Munich and Salzburg, forming a crucial axis in southern Germany and connecting to Austria and the Alpine rail network. The route serves international traffic between Munich Hauptbahnhof and Salzburg Hauptbahnhof while integrating with regional services to Rosenheim, Freilassing, München-Pasing and freight corridors toward the Brenner Pass and Innsbruck. It is a backbone for long-distance services such as ICE, EuroCity, and cross-border regional links operated by Deutsche Bahn Regio and ÖBB.

Route

The route runs east–southeast from Munich Hauptbahnhof through suburban nodes including München-Pasing, München-Neuaubing, and München-Freiham before traversing the Isar floodplain to reach commuter hubs like Dachau and Freising; it continues via Rosenheim station, skirts the foothills of the Bavarian Alps, passes through Traunstein environs, and terminates at Salzburg Hauptbahnhof adjacent to the Salzach river. Along the corridor it interchanges with lines to Nuremberg, Augsburg, Regensburg, Garmisch-Partenkirchen, and international routes toward Innsbruck, Linz, and Villach. The alignment negotiates river crossings, urban approaches, and freight yards such as Munich North marshalling yard and connects to intermodal terminals serving Munich Airport via the broader Bavarian network.

History

The line was developed in the mid-19th century amid a wave of railway expansion fostered by the Kingdom of Bavaria and industrial interests from Austro-Hungarian Empire markets. Construction involved engineers associated with the Royal Bavarian State Railways and private contractors who linked Bavarian trade hubs to the Austro-German customs union corridors. During the World War I and World War II periods the corridor was a strategic transport artery for troop movements and logistics between Germany and Austria, later undergoing reconstruction during the Allied occupation of Germany. Postwar economic recovery and the European integration process drove electrification and capacity upgrades overseen by entities including Deutsche Bundesbahn and later Deutsche Bahn; cross-border coordination with ÖBB enabled the modern interoperable timetable and signalling conversions aligned with TEN-T priorities.

Services and operations

Long-distance services include ICE trains providing high-speed links to Berlin, Frankfurt am Main, and Vienna via Salzburg, as well as EuroCity and InterCity services linking Munich to Zürich, Milan, and Budapest. Regional operations are provided by Regional-Express and S-Bahn München extensions, with cross-border regional trains coordinated with ÖBB timetables. Freight services convey containerized traffic, automotive shipments to and from manufacturers such as BMW and component suppliers, and transit freight toward the Brenner Base Tunnel corridor. Operational management relies on traffic control centres modeled after those used by Deutsche Bahn Netz and interoperable train control protocols in partnership with ÖBB Infrastruktur AG.

Infrastructure and engineering

The corridor features double track throughout with sections upgraded to four tracks approaching Munich Hauptbahnhof; electrification at 15 kV 16.7 Hz AC overhead catenary complies with German and Austrian standards. Signalling has migrated from mechanical and relay-based interlockings to computerized systems including ETCS pilot deployments and digital interlockings. Key engineering structures include bridges over the Isar and Salzach rivers, tunnels in the Alpine foreland, and grade-separated junctions at nodes such as Rosenheim station and Freilassing station. Track geometry and ballast improvements have enabled higher line speeds and axle-load increases to support heavy freight; noise abatement measures mirror best practice in the Federal Immission Control Act context and local Bavarian planning frameworks.

Rolling stock

Long-distance services use DBAG Class 403 and DBAG Class 412 high-speed multiple units for ICE routes, alongside locomotive-hauled EuroCity consists often featuring ÖBB Railjet equipment on cross-border diagrams. Regional services deploy Bombardier Talent 2 EMUs, Siemens Desiro units, and refurbished DBAG Class 101-hauled regional coaches; ÖBB contributes Siemens Taurus (ÖBB) locomotives and ÖBB Cityjet EMUs on cross-border trips. Freight traction includes diesel and electric locomotives such as DBAG Class 185, DBAG Class 193 (Vectron), and ÖBB freight fleets. Maintenance and stabling occur at depots in Munich Ost and Rosenheim with component support from suppliers like Siemens Mobility and Bombardier Transportation.

Future developments and upgrades

Planned developments encompass capacity expansion measures tied to European freight corridors, implementation of full ETCS Level 2/3 signalling, noise barrier projects, and station modernisations at strategic hubs including Rosenheim station and Freilassing station. Projects linked to the Brenner Base Tunnel and TEN-T freight priorities will shift long-distance freight flows, prompting yard rationalisation and electrification enhancements. There are proposals for incremental speed upgrades enabling 200 km/h operation on extended sections, procurement of additional cross-border rolling stock compatible with multi-system electrification and ETCS, and integration into regional mobility plans coordinated by Bayerische Eisenbahngesellschaft and Landeshauptstadt München authorities. Investment programmes involve Federal Ministry of Transport and Digital Infrastructure funding streams and European Union cohesion funds supporting interoperability and climate-aligned modal shift toward rail.
