Yes, it's like a ticket booth. Ex. Lets say you want to go to a certain continent/island. So you travel to a certain town that has this "travel system" on the continent/island your on, and you pay a certain amount of gold/money. When you get there, you can click on which continent you wish to travel to, BUT you have to explore in order to travel to hidden travel stations(Except the default : Which take you to each continent : in order to explore the others) and you can click which continent, and then it zooms in or something and all of the stations you've explored reveal, then you click one and you enter that town/city.
I hope you can understand that, i didn't really know how to word it.
