This is a minecart station which you can have 4 destination of places connect to, it has a system which we reset as soon as the player has left the station by minecart and has a system which the player will be sent back to the station if they do not choose a destination, or if they come from the opposite direction. Most of the redstone is not visible, but some is, if you wish to hide this redstone feel free, but it don't mess up the redstone or it won't work. If you use this on a server please give me some credit as "vatvat3". Also if you would like to take this out as a world edit schematic there is a glowstone square for a ruff guide to were to make your selection.
Happy Minecarting
