Nora’s Rail Optimization

04.06.2026 Mods noramibu 0 comments 2 min 95 views

A simple Rail Optimization mod that makes powered/activator rails turn on/off up to 4x faster. Fork of RailOptimization which is fork of FXRailOptimization.

## Why fork of a fork?

Because both FX and EasterGhost doesn’t maintain it’s own repository any longer, and EasterGhost’s added configuration doesn’t actually work in-game, but this fork is fixing this issue.

Description

It is a simple mod that makes powered/activator rails turn on/off up to 4x faster. The best working condition is that you feel nothing when it is operating but smooth and fast rail updates. This mod is fork of EasterGhost’s RailOptimization mod, which is actually fork of FXMorin’s mod. Thanks to both of them for bringing this mod to us.

Before you download

Please allow me to convey my sincere gratitude towards FX Morin for his code! Most of the code are written by FX Morin and I just do some little adjustment to make it operating.

What’s new

An update of FX’s RailOptimization for 1.21.x (fabric) and 26.1x (multiloader).
Fix the severe crash when loading the mod.
Lighter code implementation by removing architectury API.

Known issue

Incompatible with any version of Carpet TIS Addition(CTA).

Reason

Method used to optimize the rail’s performance is conflicted with CTA’s update mechanism. CTA uses various methods to edit or avoid updates including rail’s update(e.g. railDupingFix). Method conflicts will cause some unpredictable failure when injecting mixin and it’s truly appeared.
