Description
RailOptimization is a lightweight mod that makes powered rails and activator rails turn on and off up to 20x faster in complex rail networks.
The best result is that you notice nothing while it is operating, except smoother and faster rail updates. Vanilla behavior and the default power range are preserved unless you explicitly change the range.
Performance
| Benchmark scenario (use v2.0) | Fabric (up to) | NeoForge (up to) |
|---|---|---|
| Straight rail state changes | 9.38x | 16.69x |
| Mixed-slope state changes | 12.09x | 22.93x |
| Repeated unchanged-state updates (indirect power) | 48.69x | 38.30x |
Snapshot:
| Benchmark scenario (use v2.5-snapshot.2) | Fabric (up to) | NeoForge (up to) |
|---|---|---|
| Straight rail state changes | 16.06x | 28.40x |
| Mixed-slope state changes | 21.44x | 38.28x |
| Repeated unchanged-state updates (indirect power) | 52.27x | 40.15x |
Measured in local multi-round benchmarks at the default power range of 8 with updating length 17, comparing optimized and unoptimized rail updates on the same mod loader. Actual gains vary with rail layout, server load, hardware, power range, and other installed mods.
State-change results include both turning rails on and turning them off. The unchanged-state result measures repeated updates without a power-state change; it is not an on/off speedup or a whole-server speedup.
Features
- Fast updates across straight, ascending, descending, and mixed-slope rail networks.
- Greatly reduced cost for repeated updates that leave rail state unchanged.
- Optional power range from 1 to 64, with vanilla's default of 8 unchanged.
- Switch between vanilla and optimized update logic without restarting.
- Native builds for Fabric, Forge, and NeoForge, with no Architectury API dependency.
Install it with the default settings and it works without additional configuration.
Commands
| Command | Purpose |
|---|---|
/railoptimization | Show the current state and power limit |
/railoptimization on | Enable the optimized update path |
/railoptimization off | Use vanilla update logic |
/railoptimization powerLimit <value> | Set the rail power range from 1 to 64 |
/railoptimization reload | Reload the configuration file |
Changing settings requires administrator permission. Settings are saved automatically in railoptimization.json and persist across restarts.
Compatibility
- Choose the file for your Minecraft version and mod loader.
- RailOptimization v1.2 and earlier are incompatible with Carpet TIS Addition. RailOptimization v1.3 and later are compatible.
- To compare a contraption with vanilla, use
/railoptimization offand trigger it again. If you find a behavioral difference, please report it with a minimal reproduction.
Acknowledgements
RailOptimization began as a fork of FxMorin's RailOptimization. My sincere thanks go to FxMorin and the original contributors for their work. The current implementation has since been extensively rewritten, but this project would not exist without their original work.
Special thanks also go to JellySquid, 2No2Name, and the other Lithium contributors. RailOptimization's rail-specific batch-write design was developed by studying and drawing on their source code and existing palette and chunk-storage optimizations. When Lithium is installed, RailOptimization uses its optimized palette and bit-storage implementations and integrates with its block-change tracking. Lithium remains optional.

## RailOptimization v2.5-snapshot 1
> This snapshot introduces a new batch-write and notification engine for faster powered and activator rail updates. RailOptimization 2.0 remains the stable release while feedback is collected.
### Improvements
- Added rail-specific batch writes grouped by chunk section, developed by studying and drawing on Lithium's source code and its existing palette optimizations, to reduce the overhead of turning rails on and off.
- Batched neighbor notifications and removed repeated NC updates while retaining vanilla-compatible update ordering and native nested-update processing.
- Combined signal searches with depower planning to reduce repeated work when turning rails off.
- Reused chunk and section references during signal checks and neighbor notifications, while continuing to read live block states.
- Preserved Lithium's block tracking and cache invalidation when using batch writes. Lithium remains optional.
### Performance
| Combined on/off updates | Fabric (up to) | NeoForge (up to) |
| ----------------------- | ---------------: | ---------------: |
| Straight rails | **15.10x** | **26.04x** |
| Mixed-slope rails | **20.07x** | **34.20x** |
Measured locally at the default power range of 8, without Lithium, using per-run median timings against the same loader without RailOptimization. Actual gains vary with hardware, JVM, server load, rail layout, and other installed mods; these are rail-update speedups, not whole-server speedups.
The default power range, commands, and configuration remain unchanged. Please report any differences from vanilla behavior with a minimal reproduction.
### Acknowledgements
Special thanks to JellySquid, 2No2Name, and the other [Lithium contributors](https://github.com/CaffeineMC/lithium) for the source code and optimization work that informed this batch-write design. When installed, Lithium also supplies the optimized palette and bit-storage implementations used by RailOptimization. Lithium remains optional.
