Train Network Optimisations Mod FAQ

10 questions players actually ask, answered.

Do I need to do anything to activate this mod or does it work automatically?
The mod works automatically once installed—there are no configuration steps or activation required. It starts optimizing your rail networks the moment you load a world.
Why do my train tracks still lag when I build really long lines?
Make sure the chunks containing your tracks are actually loaded; the mod only optimizes connections between loaded chunks. If you're building across very distant terrain, lag may occur in unloaded areas until those chunks load naturally.
Does this mod work with other train mods like Immersive Railroading or Create?
This mod is designed to work standalone and optimizes vanilla Minecraft rail mechanics; compatibility with other train mods depends on how those mods handle track connections, so results may vary.
What's the difference between this mod and just building tracks normally?
Without this mod, the game tries to calculate connections for all nearby tracks including those in unloaded chunks, causing lag spikes. This mod only processes loaded chunks, letting you build massive networks without slowdowns.
Can I use this mod on a multiplayer server?
Yes, the mod can be used on servers and will help reduce lag for all players when building and maintaining rail networks across the world.
Does this mod change how minecarts move or behave?
No, minecarts move and behave exactly as they normally would—the mod only changes how the game connects track pieces behind the scenes.
Will this mod help if my world already has lots of generated rail tracks?
Yes, the World Generation Fix feature prevents lag from naturally-generated tracks in distant chunks, so it will improve performance even in worlds with existing rail systems.
Do I need to rebuild my existing rail networks for this mod to work?
No, the mod applies to all tracks in your world automatically—existing rail networks will benefit from the optimization without any rebuilding.
What happens when I load chunks that contain tracks I built far away?
When distant chunks load, the mod will connect any track pieces in those chunks to your existing network if they're within connection range, just as it would for newly-placed tracks.
Can this mod cause desync issues or break my world?
No, the mod only optimizes how tracks connect and doesn't alter world data or minecart mechanics, making it safe for any world.
