In Germany, the confessional trade union association (CGB - Christlicher Gewerkschafts Bund CGB) has called upon the city state of Bremen’s new Senator for Environmental affairs, Maike Schaefer (Green Party) to use the tracks of the Bremen tram network for cargo transport
This transport mode has a long history in Germany and cargo trams are used in leading European cities in Zurich and Vienna.
The obvious example today in Germany is Dresden. Between 2001 and 2016 VW used "CargoTrams" to transport automotive car parts between a logistics centre and its local car plant. One CargoTram is equivalent to three 18.75m long drawbar rigs
The operation was suspended in 2016 when VW ceased production of Phaeton cars, but it has now been reintroduced to support production of the new eGolf electric car (photo above from René Meinig/Sächisher.de).
The local tram gauge is 1,450mm and the trams run three times a day each way on the 6 kms long track between the logistics centre and plant. There have reportedly been no conflicts with passenger services and the local tram operator is the same for both services.
