Planned

Copper Rails

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): CopperRails did not start: java.lang.NoClassDefFoundError: net/minecraft/world/level/block/WeatheringCopper; CopperRailsClient did not start: java.lang.NoSuchMethodError: 'java.util.Optional net.fabricmc.loader.api.FabricLoader.getModContainer(java.lang.String)'.

What it needs from Kiln

Mixin
net.fabricmc.fabric.api.registry.OxidizableBlocksRegistry
net.fabricmc.fabric.api.resource.v1.ResourceLoader
net.fabricmc.fabric.api.resource.v1.pack.PackActivationType
net.fabricmc.loader.api.ModContainer
net.minecraft.world.level.block.PoweredRailBlock
net.minecraft.world.level.block.WeatheringCopper
net.minecraft.world.level.block.WeatheringCopper.WeatherState

net.minecraft.world.level.material.MapColor
FabricLoader.getModContainer()
Component.nullToEmpty()
Level.hasNeighborSignal()

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)

In the author's words

Enhances minecart transportation with new rails : oxidizable copper rails and crossings

Scanned on 4 November 2026 against Kiln 0.2.0, file copperrails-1.1.1+mc26.3.jar. The scan reads the mod's classes; it does not run them.
