What exactly do you mean?
Do you want to know which packets to use to show the station to the client?
Or do you want to know how to add the station to the game in the first place?
In both cases provide more information such as which version of the game you are using, and in what language your emulator is.
Also please tell me that you know how to use the language you chose for your emulator (if you downloaded one from the internet) if not please learn before trying to make a server, messing with this kind of thing is very complicated for you to learn while doing!
But you can use the code as a base if you want to learn how certain things work.
