RealTrainModRenewed


RealTrainModRenewed is a modernization fork of RealTrainModUnofficial for Minecraft Java Edition 26.1 with NeoForge, written in Kotlin and Java.

It brings Japanese trains, tracks, signals, and railway systems to modern Minecraft while maintaining compatibility with the existing RTM ecosystem.

Goals

• ✅ Port RealTrainMod to modern Minecraft with NeoForge
• Maintain compatibility with legacy RTM model packs, vehicles, rails, signals
• ✅ Gradually rewrite the codebase in Kotlin
• Improve maintainability and developer experience
• Target the next NeoForge LTS when available
• New feature…?

Build

./gradlew build

Known Issues

• Train movement jitter during interpolation
• Legacy model scripts need compatibility work (RTM/KaizPatchX helper APIs)
• Some sound scripts need exact mapping verification

These are deferred until the Kotlin rewrite progresses further, unless they block compiling, launching, or basic vehicle placement.
