Railway Tools For Axioms

Railway Tools For Axioms is an addon for Axiom, the editing mod, and needs Axiom and Fabric API to run. Its tool places rails along a Catmull-Rom spline through the points a builder sets, so curves stay smooth and free of sharp corners between segments. Block choice and orientation are computed automatically from the local path tangent and curvature, which removes the need to place each block by hand.

Two placement styles can be selected from the tool panel. The Classic style uses dead fire coral wall fans, centerline markers and mud brick walls, with lateral supports and curve indicators; it suits survey planning. The Natural style uses lecterns, pale moss blocks, gravel, leaf litter and spruce shelves for a more organic look. An optional ground-snapping mode searches vertically for the nearest solid surface so the path follows existing terrain. Spline sampling density can be set from 2 to 32 points per block, and higher values help on tight bends.

The mod is designed for large-scale building projects such as BuildTheEarth. The author states that the project is unofficial and not affiliated with the original creators. Servers need the Axiom permission nodes listed in the documentation for players to use the tool. Files target 1.21.10 – 1.21.11, and the latest Fabric build, 2.0.0, is for 1.21.11. The mod is client-side only and released under the MIT License, but it is not open source.
