[video] Cargo trams (not trucks) should be how we move goods in our cities

I think a good use would be to go from an industrial area to another, or to a cargo hub.

Use trams to get goods to neighbourhoods, then distribute from there.

Practically every street has stores

Mmh in my experience actually not. Very distinct streets in the centre are shopping streets (with residential on the higher floors). Many neighbourhoods are just residential.

Trains to distribution center, pneumatic tubes from distribution center to every home and business.

I want my green steampunk future cities.

while you could argue the specialized electric buses and delivery vans are "Cars" they cannot drive on normal roads and do not produce pollution, in terms of emissions or noise, like regular cars. It's more than possible to build a car free city, its been done before.

I believe the tracks for the long distance trains should go to warehouse or distributions whatever then cargo bikes would deliver them locally.

The answer should be yes. In fact we should dig up the bicycle lanes to make way for tram tracks.

Sounds like a pretty niche use case, there's not many factories in the middle of cities that have a tram line running to them.

And at 15 tonne per car, 7.5 in the end cars, the payload isn't particularly impressive either.

This also didn't deliver product to the final destination, which is what most urban trucks are doing.
