Frankfurter Feldbahnmuseum

In Frankfurt am Main‑Bockenheim, the Frankfurter Feldbahnmuseum e. V. presents the technology and history of 600 mm gauge field railways. As a stop on the Route der Industriekultur Rhein‑Main, it is one of the city's important technology museums.

The association was founded in 1975 under the name Frankfurter Schmalspurfreunde; from 1976 museum operations began on the site of a gravel pit in Mainflingen. Because of ongoing gravel extraction, the collection moved in 1979 to the site of the former Bundesbahnausbesserungswerk in Frankfurt‑Nied. A further relocation followed in 1981 when the works site was to be developed. After that, the Bockenheim depot of the Frankfurt tramways, which had previously not been open to the public, could be used, allowing the vehicles to be housed there but not permitting regular running. In 1985 the city provided a site at Rebstock, on which a vehicle hall and a permanent track were constructed; in 1987 the Frankfurter Feldbahnmuseum at Rebstock was opened.

The museum railway was gradually expanded. Since 1991 a roughly 1,200‑metre line has been operated on several weekends each year; at the termini Kaiserdamm and Alter Flugplatz, and at the museum, the locomotives are run around. Additional carriage sheds were put into service in 2005 and at the end of 2007. On 31 May 2008 the museum extended the line by about 300 metres to the terminus Rebstöcker Wald. The museum is a member of the Hessischer Museumsverband and of the Deutschen Museumsbund.

The vehicle collection is among the more extensive of its kind in Germany: more than 70 locomotives and around 200 wagons. These include 20 steam locomotives, 40 diesel locomotives, 4 petrol locomotives, 4 electric locomotives and 13 special rail vehicles. Most locomotives are privately owned, many wagons belong to the museum; 13 steam locomotives are currently operational.

Manufacturers represented include Maschinenbau‑Gesellschaft Heilbronn, Henschel, Decauville, Orenstein & Koppel (O&K), Jung, Borsig, Hanomag, Baldwin and Krauss. Of particular note are a very small O&K Mallet articulated locomotive with 30 PS and the only operational En2t Heeresfeldbahn locomotive with Luttermöller drive, which is known for its excellent curving performance. A Deutz CV petrol locomotive, regarded as the oldest motor locomotive preserved in its original condition, is listed in the collection as a loan from the Deutsches Museum München (since early 2015).
