Delivery people using the trams to get around the city.
Freight tram trials planned in Karslruhe
They might be a chance in Sydney depending on the route what what would they carry parcels?Just what could they carry and to where ?.
The famous Dresden car-go-trams were part of a government imitative to boost manufacturing in the city, so they dangled cash in front of VW to setup the ' Transparent Factory' in Desden as a job creation and training scheme. The signature factory was built in the middle of the city next to the main city park. They didn't want semi trucks pounding through the historic city centre to the car-go-trams were built out of the chassis of withdrawn tram stock to carry parts to the factory. VW kept trying to switch back to road transport and eventually closed the factory when they stopped making the sole model car the factory was equipped to build. (I believe they have been convinced to re-open it with a new product line).
But it's a show factory - I don't think it was ever considered commercially viable on it's own.
Interesting to see more freight trams, could there even be some quadruplication of some sections of the network so that freight trams can pass stationary passenger trams?No. It will not happen.
