I'm wish to have German streetcars before WW2. I want to stimulate the tram-network Berlin in the late 1920s. The trams had a length around 10m, bi directional and trolleys... perhaps somebody can help me.

Thanks Marc

The best of the kind on the workshop right now is this mod - https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2601159355&searchtext=horse

Not exactly what you are looking for but sort of close. You can also relatively easily modify it to your needs, it's not that difficult. Not sure if practically speaking you can expect to have a mod in a short time, so I would not wait for it if you want to build a 1920s network (which is a great idea!)
