Heyo, Kordon here! We don't have a railway yet. I say yet because I also had ideas of a rail connecting bases that sign up to the nearest station. Two problems though, we already have a nether tunnel system so if someone really wants to get somewhere fast, that's the way to go. And if i actually followed through with it, I would make it free to ride because then less possible riders would use it.
Don't get your hopes up though, I had a place for the main station in mind and I haven't gone over it with Kathi yet Kathi don't hurt me ;-;
