Dependencies and Compatibility

Required Runtime Dependencies​

BetterRailwaySystem currently expects:

  • Minecraft 1.21.1
  • Fabric Loader
  • Fabric API
  • Cloth Config
  • Java 21+

Vanilla Compatibility​

The mod is designed around the vanilla rail system:

  • normal rails
  • powered rails
  • detector rails
  • activator rails
  • redstone-based station logic

The goal is to extend behavior without replacing the track system itself.

Client and Server Compatibility​

Fully Supported​

  • singleplayer
  • LAN worlds where both sides have the mod
  • dedicated Fabric servers with matching mod installation

Limited​

If the client joins a server that does not run BetterRailwaySystem:

  • line-map requests are disabled
  • server asset upload and sync are disabled
  • other server-backed operations are gated off instead of trying to run incorrectly

This behavior is intentional and avoids broken UI or misleading interactions.
