I want to create a new city

[jaunco]

What I want to do is: when I start the new game, go to an open field and start building streets, roads, stations, etc. and when this is finished, establish it as a city so that people move there and begin to grow. Can you do this in the game? Is there any mod that does it?

since we are here I want to add another question: when you demolish a residential building, the population of that building disappears or moves to another part of the city?

No, and no.
They disappear.

This is not a city-builder like Cities Skylines.

However, there are mods that let you plop some city buildings and fixtures down, "creating" a town. The Bad News is, those buildings are for decoration only and don't "work" (grow) like the game's real city buidings.

a good way if you want to make a town of you own start the game grow the town once you at least one type of building on the out skrits of town where it will still show demand then you can get rid of the main part of town and start the build and @genemead is right on the plop buildings but in when you place them in a real town they will sometimes become a part of town and reset as a reg town building and the buildings do work not like what you would think they are for decoration but they have the option to ask for people when you set it on high its nuts in a plop city but it brings profit to bus lines after 15 to 20 plop buildings are in the town
