Arbeitsgemeinschaft Geesthachter Eisenbahn, Railway museum in Hamburg, Germany

The Geesthacht Railway Association operates train rides on a route spanning approximately 14 kilometers between Hamburg-Bergedorf and Geesthacht using historic locomotives and original preserved carriages. The line runs through northern German countryside and features vehicles from the early 1900s through the post-war era.

Railway enthusiasts and railway workers founded the association in April 1975, registering it in Geesthacht, to keep the history of the Bergedorf-Geesthachter Eisenbahn alive. No BGE locomotive could be found, as the last surviving one belonged to the Braunschweiger Eisenbahnfreunde, so an AKN diesel hauled the first train. A first steam locomotive was bought and used in 1976; the Danish DSB locomotive Q 350, called "Karoline", followed in 1981.

The collection displays steam locomotives and carriages from different periods of German railway history, which visitors can see and experience during the rides. These working vehicles shape the character of the journey between the two towns.

Visitors should note that rides are offered seasonally and typically run on weekends, making advance planning useful. The stations in Bergedorf and Geesthacht are accessible by public transportation, and the journey itself takes about one to one and a half hours.

The association's steam locomotive Q 350, nicknamed "Karoline", was built in 1945 by Frichs in Aarhus as a Danish State Railways shunting engine. It came to Geesthacht from Denmark in 1981 and was badly damaged on 9 June 2019 when a car struck its running gear at a level crossing.
