The Anchor Cart is a special type of minecart from the Railcraft mod. This cart acts as a chunk loader, functionally the same as the World Anchor. The difference being that this variation is mobile and has a slightly larger radius. It will attempt to load 25 chunks (a 5 by 5 square) around it at all times, as long as there is sufficient fuel in it. Fuel for the Anchor Cart is Ender Pearls, and each Ender Pearl will allow the cart to load chunks for 12 real-life hours by default.
