How to change the global minecart speed with the gamerule

The mod's main control is a single gamerule that sets how fast carts can travel in your world.

Steps

1. Make sure you can run commands. You need operator permissions, or cheats enabled in a singleplayer world.

2. Check the current value by running the gamerule with no number:

/gamerule minecartMaxSpeed

3. Set a new value by adding a number:

/gamerule minecartMaxSpeed <value>

4. Place a short test track with powered rails, get in a cart and ride it.

5. Adjust the value up or down until the ride feels right.

Tips

• Raise the value in small steps rather than jumping straight to the maximum. Vanilla carts top out at 8 m/s, and the mod can go up to 34 m/s depending on configuration.
• At high speeds you can outrun chunk loading, especially on servers. If the world stutters or you see terrain popping in ahead of you, lower the value.
• The gamerule is saved per world. On a server, set it once in the server console or in-game as an operator.
• This value is the general speed cap. The rider-specific gamerules (see the other guides) can give players, mobs and empty carts their own speeds.
