[2] The station is served by about 150 trains daily of Deutsche Bahn, Bayerische Regiobahn (a subsidiary of Veolia Verkehr, BRB) and Regentalbahn, including 50 services of the Munich S-Bahn.

The station was only built with the opening of Ammersee Railway from Augsburg to Schondorf on 30 June 1898 (and completed to Weilheim on the 24 December 1898) at the junction of two lines near Geltendorf.

In 1907, the Allgäu Railway was duplicated and, as a result, Geltendorf station was expanded to five tracks and received an underpass to the central platforms.

In World War II, a bunker was built at the station for the railway employees.

Between 18 June 1944 and the 27 April 1945, concentration camp prisoners were transported on both lines through Geltendorf station.

In 1979, the operations office in Geltendorf was disbanded and supervision of the station was assigned to Kaufering and later Buchloe.

With the introduction of the S-Bahn, the former ticket gates were removed and passengers could now enter the entire station area without supervision.

In 1974, the class 628 electrical multiple unit was officially inaugurated at Geltendorf station.

It had two water tanks on the top floor and basement premises for the employees of the track supervisor.

To the north of the tracks there was a makeshift wooden building that served the administration and the train dispatcher.

The station is located in the area of the Münchner Verkehrs- und Tarifverbund (Munich Transport and Tariff Association, MVV).
