LMFAO, territorial walls? I can jump over your wall without building anything
Edit: UPDATE! Other than that old news, a railway link has been added!
Karlsland station is still in development, but I have created a mini stop at the co-os on the pic below of where the stop will be, from there, it will have a button launch system to continue to the other place, or stop to catch the karlsland railway.
So far, so good, still got a lot of digging to do.
