Minecart Upgrade is a Fabric mod that raises the maximum speed minecarts can travel on rails.
Minecart Upgrade is a lightweight Fabric mod that revolutionizes minecart travel in Minecraft. Say goodbye to the vanilla speed limit and experience the thrill of high-speed rail travel with intelligent physics handling that keeps your carts safely on track!
Use the game rule command to change the maximum speed on the fly:
/gamerule minecartMaxSpeed <speed>
Examples:
| Command | Result |
|---|---|
/gamerule minecartMaxSpeed 8 |
Vanilla speed |
/gamerule minecartMaxSpeed 12 |
Default mod speed (50% faster) |
/gamerule minecartMaxSpeed 20 |
Rapid transit speed |
/gamerule minecartMaxSpeed 50 |
Extreme speed (for the brave!) |
💡 Tip: The speed is measured in blocks per second. Vanilla Minecraft caps minecarts at 8 blocks/second.
For the best experience at high speeds:
| Recommendation | Reason |
|---|---|
| ✅ Use straight rails | Maximum speed potential |
| ✅ Use powered rails frequently | Maintain momentum |
| ⚠️ Be cautious with curves | Auto-limited to 25 b/s |
| ⚠️ Be cautious with slopes | Auto-limited to 25 b/s |
| ⚠️ Be cautious with high limits | Minecart pysics glitches >~20 b/s |
| 🔥 Use furnace minecarts | Can push other carts at high speed |
The easiest way to configure the mod in-game:
/gamerule minecartMaxSpeed <blocksPerSecond>
18.5)12.00.1Located at: config/minecartupgrade.json
{
"maxBlocksPerSecond": 12.0
}
The mod implements intelligent speed limiting to prevent physics issues:
| Track Type | Speed Behavior |
|---|---|
| Straight rails | Full configured speed |
| Curved rails | Capped at 25 b/s if configured speed exceeds it |
| Ascending/Descending rails | Capped at 25 b/s if configured speed exceeds it |
| Rails in water | 50% of normal speed |
When a minecart would normally derail:
When a furnace minecart collides with another minecart:
A: Yes! The mod works on both client and server. For multiplayer, only the server needs the mod installed. Clients will automatically benefit from the increased speeds.
Q: Do minecarts derail at high speeds?A: The mod includes smart re-railing technology that keeps minecarts on track. However, at extremely high speeds (50+ b/s), complex track layouts may still cause issues. The mod automatically limits speed on curves and slopes to 25 b/s to prevent most derailments.
Q: Can I use this with other minecart mods?A: Generally yes, but compatibility depends on the other mod. If another mod also modifies minecart physics, there may be conflicts. Test in a development world first!
Q: Why is my speed capped at 25 b/s on curves?A: This is a safety feature! At speeds above 25 blocks/second, minecarts can behave erratically on curves and slopes. The mod automatically reduces speed in these situations to keep your cart on the rails.
Q: Can I disable the mod for specific worlds?A: You can set the game rule to vanilla speed (/gamerule minecartMaxSpeed 8) for a vanilla-like experience while keeping the mod installed.
A: The mod is very lightweight and should have negligible impact on performance, even with many minecarts.
