The Dachau–Altomünster railway, also called the Bummerl, Bockerl or Ludwig Thoma Railway, is a railway in the German state of Bavaria. It is part of the Munich S-Bahn network and is integrated within the Münchner Verkehrs- und Tarifverbund (Munich Transport and Tariff Association, MVV) as line S2. The branch line connects the town of Dachau on the Nuremberg–Munich high-speed railway with Altomünster. Markt Indersdorf is an important stop. Until its electrification in 2014, it was the only non-electrified line of the Munich S-Bahn and was designated as line A.
At the beginning of the year 1900 it was decided to build a railway line from the Munich–Ingolstadt line (now part of the Nuremberg–Munich high-speed line) for the development of the hinterland of Dachau. There were two option for the route: connecting Altomünster via Schwabhausen and Erdweg from Dachau station or connecting Markt Indersdorf from Hebertshausen.
The respective municipalities could not agree on one or other the routes and so came to a compromise. This compromise is reflected in the present route. First it runs west to Schwabhausen, then continues north to Indersdorf and turns back to the southwest to run up the Glonn valley to Erdweg. From there, the line heads back to the northwest to Altomünster. This means that the line takes 29.9 kilometres between Dachau and Altomünster, which are about 20 kilometres apart in a direct line.
The first section from Dachau to Indersdorf was opened on 8 July 1912 and the whole line to Altomünster was commissioned as the "Dachauer Lokalbahn" on 18 December 1913.
At the time of the Bavarian Soviet Republic, the local railway was an important economic factor for the revolutionary government. The money printed in the paper mill in Dachau could be transported directly to Munich without substantial detours.
