{| class="wikitable" |- ! Value ! Description |- | false | Disables the chunk loader. The train will now unload if no player is nearby. |- | true | Enables the chunk loader with a radius of 5x5 full entity-ticked chunks. In effect this loads a 9x9 area of chunks. Equivalent to <code>full 2</code> |- | minimal 0 | Enables the chunk loader, but only loads the chunks the train is inside of. Does not simulate entities or redstone (except for the train itself). This has the most performance and is suitable for long-distance travel. |- | redstone 2 | Enables the chunk loader, loading and simulating a 5x5 block-ticked (redstone simulated) chunks, and an outer 7x7 layer of non-simulated chunks. Useful at stations when redstone has to be simulated, but entities at these stations don't need to be ticked. |- | full 10 | Enables the chunk loader, loading a 21x21 area of chunks and simulating entities inside. A 23x23 layer around it is block-ticked, and another 25x25 layer around that is not simulated. So this is actually loading 25x25 chunks. If you're looking for a chunk loader that acts like a Player, this is it. |}
