The society was founded on 8 December 1965 by a group of tramway fans within the so-called Verkehrsfreunde Stuttgart society, that had signed up for the preservation and care of the last remaining railcar, no. 126, from the former Filderbahn as well as other historically valuable trams. After the Stuttgart Tram Company had shown no interest in building up a museum collection and the Filderbahn railcar 126 could only be preserved by keeping it at Ludwigsburg, the GES turned at the end of the 1960s to the more promising theme of opening a railway. The engagement of the GES for the preservation and subsequent restoration of the Filderbahn wagon laid the foundation stone for the present-day collection of the Stuttgarter Historische Straßenbahnen.
