Other suggested links (to Freising, Passau or Rosenheim) were rejected by the railway board.

The contract for the construction of this railway was signed on 9 May 1870 by the town of Erding and the Head Office of the Royal Transport Institution (German: Generaldirektion der königlichen Verkehrsanstalten).

Altenerding station was opened on 1 May 1899 in the then independent municipality and a second track was built to allow trains to cross in preparation for the introduction of the 20 minute interval services on the Munich S-Bahn in 1981.

The terminal station of Erding has two tracks next to a central platform and train stabling sidings.

[2] As part of the "Erding Ring Closure" (Erdinger Ringschluss) it is proposed that the line will be extended to the north-west to Munich Airport.
