How do I install RR Additions?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does RR Additions work with?

The listing gives Minecraft 1.21.1, 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

RR Additions

by RedstoneGyerek · on CurseForge

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

⬇ Download for 1.21.1 · NeoForge ⬇ Download for 1.20.1 · Forge

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This mod aims to add railway decorations to the game, from all around the world. Why? Because I haven't found a mod like this for my 1.20.1 survival server.

Notes:

If you wanna set up a crossing signal, then you'll first need to place down a base, then you can place other parts on top of that. If you're making for example a "∩" shape, leave a block gap between the legs of that "∩", or your pc will suffer of infinite while loop. Because of this, there is a 10 step limit in place, and so you cannot build 11 block assemblies.

Activate signals at the base with at least one redstone dust connected to them.

Right click on blocks with the wrench to change variations.

Old name: RR Crossing stuff

Kinda inspired by Traffic Control made by CSX8600
