CartUpgrader
by Luan-Fuzi
CartUpgrader changes what happens to minecarts with a container when they are destroyed, so the contents and the cart itself drop instead of vanishing.
What it does
When a minecart carrying a chest, hopper, furnace or TNT is destroyed, the mod lets that cart drop as an item and releases what it held. The behavior covers the plain minecart and the four container carts, so a broken hopper or chest cart no longer costs the player its inventory.
The mod is built for Fabric on Minecraft 1.16.5 and needs Fabric Loader 0.14.0 with Fabric API 0.30.0. Either side can run it, and neither needs it. The code is open source under the MIT License, and the public source repository is the only linked resource.
The author marks the mod as experimental and advises backing up saves before use. Newer behavior from the 1.19 series is noted in the author text, but CartUpgrader itself is only published for 1.16.5.
Key features
Cart drops on destruction
A destroyed minecart drops itself as an item rather than disappearing with its contents.
Container contents released
Items inside a chest or hopper cart spill out when the cart is destroyed, so nothing is lost.
Covers four cart types
The behavior applies to the plain minecart, the hopper cart, the chest cart and the furnace and TNT carts.
Experimental build
The author labels the mod experimental, so save backups are recommended before adding it to a world.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Rail transport worlds
Players who run long rail lines with item carts can recover their cargo when a cart is lost to a crash or an explosion.
Single-player and server testing
Because it is optional on either side, the mod can be tried on a local world or a test server without changing other installs.
Who it’s for: Players on Minecraft 1.16.5 with Fabric who run rail systems with container carts, and server owners who want destroyed carts to drop their items.
How it compares
RealFurnaceCarts is a Fabric mod for 1.16.4 – 1.16.5 that is client and server, under the MIT License and open source, so it covers furnace carts specifically. Gravel Carts is open source under the GNU Lesser General Public License v3.0 only, is server-side only, and targets Fabric files for 1.18.2 – 1.19, which puts it on a different version range from CartUpgrader. TNT Cart Helper is Fabric for 1.21.11, client and server, under the MIT License, and is not open source.
