A redstone-powered Emerald Rail for Fabric that boosts minecarts 15x faster than powered rails.
Screenshots


About this Mod
Emerald Rails adds a new rail to Minecraft: the Emerald Rail.
It behaves like a Powered Rail (requires redstone power to activate), but when powered it provides 15× stronger acceleration than a vanilla Powered Rail — without changing Minecraft’s built-in minecart speed cap. That means you’ll hit the vanilla cap faster, but you won’t go faster than vanilla allows unless you use another mod to raise/remove that limit.

Features
Works like a Powered Rail: powered by redstone signal.
When powered, 15× acceleration compared to vanilla Powered Rails.
Crafting
for 1.21.6-1.21.11, to craft an emerald rail, the player needs 4 emeralds, 2 redstone dust and a breeze rod.

for 1.20.1, to craft an emerald rail, the player needs 4 emeralds, 2 redstone dust, 2 prismarine crystals and a blaze rod, as breeze rods dont exist in that version.

Versions
play-tested between 1.21.6 - 1.21.11 fabric and works for any version between those two, also specifically play-tested on 1.20.1 fabric. please feel free to comment if you want a specific version, if you encounter an error or if you have a suggestion!
NOTE:
This mod does not uncap minecart speed. Vanilla minecarts have a hard speed limit, so Emerald Rails mainly helps you reach top speed much faster.
For high-speed minecart systems, a speed/physics mod is strongly recommended and close to essential, since it’s the thing that actually removes/raises the cap and lets Emerald Rails show its full effect.
