Bergische Museumsbahnen, Tramway museum in Wuppertal, Germany.

Bergische Museumsbahnen is a tramway museum in Wuppertal where historic tram cars run on original tracks through the Kaltenbach valley. The line follows the natural slopes and curves of the terrain and serves several stops spread along the route.

The tracks through the Kaltenbach valley were once part of the regular tram network serving the wider region and carried local passengers for decades. After regular service ended, a group of enthusiasts took over the line and its remaining vehicles to keep them in operation.

The line runs through woodland rather than villages, with seven stops and no town sections, following the former overland route 5 between Wuppertal and Solingen. Volunteers of the Bergische Museumsbahnen association, founded in 1969, run the service and maintain the cars, so a ride shows how the Bergisches Land's tramways once connected towns across open country.

The depot with its vehicle exhibition and bookshop lies about 50 m east of the Kohlfurth bridge, where the line begins; a track from the bridge is out of use. The museum opens Saturdays 11 am to 5 pm all year, and May to October also Sundays 11 am to 5 pm. Trams run April to October on the 2nd and 4th Sundays, plus Whit Monday and Pentecost.

The collection includes cars from several city networks: Tw 105 (Talbot, 1927) from Wuppertal, Tw 107 (DÜWAG, 1936) from Düsseldorf, Tw 275 and Tw 337 (both DÜWAG, 1957) from Bochum and Hagen, and Tw 106 (Westwaggon, 1960), which ran in Remscheid from 1969 and later in Darmstadt as No. 66.
