Munich–Buchloe–Kempten railway is a mainline railway in southern Bavaria connecting Munich with Kempten via Buchloe. The line forms a core axis within the Bayerische Regiobahn and Deutsche Bahn networks, linking the Bavarian capital with the Allgäu region and providing connections toward Lake Constance, Switzerland, and Austria. It carries regional, interregional and freight traffic and interfaces with high-speed and regional services at key junctions.

Route description

The alignment begins at Munich Hauptbahnhof and proceeds southwest through the Sendling and Fürstenried corridors before reaching the outer suburbs of Fürstenfeldbruck and Pasing. From Pasing the route continues via the historic junction at Buchloe station, where lines to Memmingen, Augsburg, and Lindau diverge. The line traverses the rolling terrain of the Allgäu foothills, passing through Geltendorf, Schwabmünchen, and Bobingen before descending toward Kempten (Allgäu) Hauptbahnhof. It intersects long-distance corridors serving Munich Airport connections and meets freight routes toward the Rhine–Main region and the Danube corridor.

History

Construction was commissioned during the 19th-century expansion of the Royal Bavarian State Railways to integrate the Allgäu into Bavarian transport networks. The initial sections opened in the early 1870s amid contemporaneous projects such as the Buchloe–Lindau railway and the Augsburg–Ulm railway. Key historical moments include strategic upgrades during the Weimar Republic era, wartime exigencies in the German Empire and Nazi Germany periods, and post-1945 reconstruction under the Deutsche Bundesbahn. Electrification and capacity works accelerated after German reunification, influenced by European transport policy developments originating from Treaty of Rome-era shifts and later Trans-European Transport Network discussions.

Operations and services

The corridor hosts a mix of services operated by DB Regio Bayern, private operators under contract to the Bayerische Eisenbahngesellschaft, and long-distance units run by DB Fernverkehr. Regional-Express services connect Munich Hauptbahnhof with Kempten Hauptbahnhof, while InterCity and occasional EuroCity trains link to Zurich Hauptbahnhof and Lindau-Reutin. Commuter traffic interfaces with Munich S-Bahn at shared nodes, and freight movements include block trains to industrial centres such as Augsburg, Ingolstadt, and ports on the Rhine. Timetabling coordinates with services on the Ulm–Augsburg railway and cross-border operations toward Austria and Switzerland.

Infrastructure and engineering

The line is predominantly double-tracked with sections upgraded to modern European Train Control System standards and equipped for 160 km/h operations in places. Major engineering works include grade-separated junctions at Pasing and Buchloe, viaducts across the Amper and Lech floodplains, and drainage schemes responding to Bavarian hydrology. Track superstructure comprises continuously welded rails on concrete sleepers, and station area realignments implemented ballast stabilization and noise barriers in urban sections. Signalling evolved from mechanical interlockings to electronic interlockings coordinated with Deutsche Bahn Netz traffic management centres.

Stations and junctions

Principal stations on the route include Munich Hauptbahnhof, Pasing station, Geltendorf station, Buchloe station, Bobingen station, Schwabmünchen station, and Kempten (Allgäu) Hauptbahnhof. Buchloe functions as a major junction with connections to Memmingen and Lindau, while Geltendorf provides interchange with regional services toward Tutzing and Weßling. Smaller halts serve commuter suburbs and tourist gateways to the Allgäu Alps, enabling multimodal links with regional bus operators such as RegioBus and seasonal shuttle services to attractions like Neuschwanstein Castle and Oberstdorf.

Rolling stock and electrification

Rolling stock on the corridor ranges from Bombardier Talent multiple units and Siemens Desiro DMUs used historically to modern Bombardier Twindexx and Siemens Viaggio push-pull sets for Regional-Express services; long-distance consists include IC coaches hauled by DB Class 101 locomotives and occasional ÖBB Railjet or SBB Re 476-hauled EuroCity trains. Electrification followed the German standard of 15 kV 16.7 Hz AC with overhead catenary; earlier diesel operation persisted on unelectrified branches until progressive wiring projects by Deutsche Bahn completed the main spine. Traction and depot support are provided at facilities in Augsburg Hauptbahnhof and Kempten depot.

Future developments and upgrades

Planned improvements include line speed increases, further implementation of ETCS Level 2 control, station accessibility upgrades funded under Bavarian transport initiatives, and capacity works to segregate freight and passenger flows. Proposals to enhance cross-border interoperability would affect services to Switzerland and Austria and align with TEN-T corridors. Upgrades to rolling stock fleets under contract tenders from the Bayerische Eisenbahngesellschaft envisage low-floor, energy-efficient trains and digital onboard systems to meet EU emissions and accessibility standards. Possible freight hub expansions aim to strengthen connections to the Rotterdam and Genoa corridors.
