The Personal Anchor is a machine from the Railcraft mod. This machine works functionally similar to the World Anchor. The Personal Anchor will keep a 3x3 of chunks loaded, as long as it has enough fuel to perform this task. Ender Pearls are used to fuel this at a rate of 1 for every 12 real-time hours. The difference between this and the World Anchor is that the Personal Anchor will only load chunks if the owner is online, and if they have visited the chunks in the anchor's range.
