This mod adds a new type of rail.
It is placed differently from normal rails, rather than connecting by default it faces whatever direction you place it in.
Due to engine limitations, it cannot go up or down hills and other rails won't connect to it.
This mod is useful if you want to enforce a certain direction on railways, or if you want to make a cart go back when it reaches the end of the track.
One copper rail is not enough to stop a full speed minecart, you must place multiple rails adjacent to each other.
The direction of the arrow shape of the rails indicates which direction carts are pushed.
