I have 4 stations and am contemplating getting a 5th.

The main station is always where your local trains will run through. They'll never go to any additional station. Even when you have multiple stations, by default, Express and International trains will go to your main station too. But there are two special buildings: one which redirects Express trains to whichever station you place it, and another which redirects International trains to whichever station you place it.

So, I have one station for local trains, one station for express trains, one station for international trains, and another station just for good looks.

Keep in mind, the trains aren't the only reason to get another station. Your main station (and each station) has a size limit. Once you hit that limit, you can only fit so many buildings. So when you have another station, you can place more buildings, which in turn bring you more passengers.
