Wuppertal, Germany in 1902
Not sure if this is the right place to post this, but i really like how calm the street scenes are without cars. There's also a 1902 / now comparison video which is kind of depressing, i thought i'd rather post something nice :)
That's excellent. Pity we don't make more use of things like that now.
Oops, just looked at the other link!
Monorails are usually not the most practical solution. In most places where you can build a monorail, a regular train is usually simpler and cheaper to build. Wuppertal has some very specific geography which causes a monorail following the path of the river Wupper to make sense, but that often doesn't translate well to other places.
Tom Scott made a video about it at some point:
