Minecart Chain with brake

Minecart Chain lets you connect minecarts together using iron chains and build simple vanilla-style trains. A furnace minecart can act as the engine, while an automatic brake lever appears on top of it when it is linked to another cart.

Features

Link minecarts together with an iron chain
Furnace minecart can pull connected carts as a train
Automatic brake lever appears on linked furnace minecarts
Click the lever to engage or release the brake
Keeps connected minecarts in order, including on corners
Maintains a controlled gap between carts to reduce collisions

Supports regular minecarts and furnace minecarts

How to Use

Hold an iron chain.
Click the first minecart.
Click a second minecart within 2.5 blocks to link them.
If one of the carts is a furnace minecart, a brake lever appears on it.
Click the lever to engage or release the brake.
Sneak-click a linked minecart with an iron chain to remove its links.

Notes

This mod is designed to feel close to vanilla Minecraft while making minecart trains more useful and readable. The furnace minecart acts as the powered cart, and linked carts follow behind it with spacing logic to prevent carts from driving into each other.
