Is there a game like this?

Hey, I'm looking for a game.

I really like city builders and games with an economy. The one game I have been playing lately is not that known about, It's called Westward IV All Aboard. It's a western city builder game set in the 1800s when the Railroads in America were expanding. Playing this game got me thinking... Are there any other city-builder games (Preferably with more depth), with an economy set in those times, particularly with an Import/Export system for railroads? I'd imagine this would work like say, your town produces certain goods and can export them to the train for cash, and any goods your town couldn't produce, or is short of, can import from the train.

I'd really like some recommendations for this kind of game, thanks!

Cities Skylines but it's set in modern day
