This is a super simplified rail system for making cart stations and rails leading all over the place. You can use this in any server or world it does not matter. You can extend the amount of rails just by repeating the pattern of the tracks and the redstone.

You can do whatever you want with it. However, it is very important that you flip off all of the levers before you switch on another. You will go down the wrong track and have to do it all over.

This can also be used for transporting items with minecart chests.
