World Anchor

The World Anchor is a machine from the Railcraft mod. This machine acts as a chunk loader, and will load a 3x3 of chunks around it loaded. The World Anchor runs on a fuel source of Ender Pearls. By default, one pearl will allow the World Anchor to keep chunks loaded for 12 real-time hours. The World Anchor will remember how many hours it has left to load chunks, even if you break it and replace it. This chunk loader can be turned off at any time via redstone signal.
