Dunac's Copper Rails
by DukeDunac
Dunac's Copper Rails adds a copper powered rail that accelerates minecarts like the vanilla gold powered rail, at a lower material cost.
What it does
Copper powered rails accelerate minecarts in the same manner as gold powered rails, applying a stronger push than the vanilla version. The mod is meant to make rail travel more practical, since vanilla powered rails give a weaker acceleration that the mod compensates for by raising the gold powered rail value. Logistics networks can swap copper rails for gold rails one to one and notice only the increased efficiency.
Minecart maximum speed rises to around 200 blocks per second. Using the mod with Minecart Improvements can force minecarts to follow its movement logic, and that setup requires players to enable Experimental Minecart Improvements. Redstone contraptions that depend on minecart timing may break, so builds that rely on it should be tested before the change is applied.
The mod targets 1.21.11 only and is published for Fabric. The server and every player need the mod installed. The code is under All rights reserved, and source code and an issue tracker are publicly linked. It is not open source.

This mod adds a new item, the Copper Powered Rail. This item functions in exactly the same way as a normal gold powered rail, but accelerates carts more slowly. As this mod is intended to make rail travel more viable than vanilla, I have compensated for this lower acceleration by significantly increasing the gold…
