Smooth Minecarts

by SequentialEntropy

Smooth Minecarts changes how minecarts take gradual curves and slopes, so carts keep their speed through turns that would otherwise slow them down.

FabricServer-side onlyMIT LicenseOpen source1.21.2 – 26.3

What it does

The mod alters minecart physics on rails. Curves that are not 45-degree diagonals are taken more quickly, and straight rails stay fast. The amount of smoothing follows how tight a curved track layout is. For each cart, the mod reads a set number of rails ahead and averages the distance to the next one. A separate check corrects the direction a cart believes it is travelling, which prevents some derailments on curved and sloped track.

Behavior is controlled by new gamerules: one sets how many rails are read ahead, another sets the smoothing factor, and the derailment check reads its own rule for how far it looks. Default and recommended values are listed in the mod's documentation. Other mods that alter minecart handling may conflict with it. Uninstalling it restores vanilla mechanics without corrupting the world. Files are published for Fabric only, for 15 release versions, 1.21.2 – 26.3, under the MIT License, and it runs on the server side alone.

Key features

  1. Smoother curves

    Minecarts turn gradual curves and slopes without the speed loss that vanilla rails cause.

  2. Adjustable smoothing

    A gamerule changes the smoothing factor, so a server can set how strongly the mod works.

  3. Derailment correction

    The cart's direction estimate is corrected on curved track, reducing derailments.

  4. Configurable sampling

    Separate gamerules set how many rails ahead the mod reads and how far the derailment check looks.

Use cases

Realistic rail networks

Builders who want long, curved minecart networks that behave more like real transit can use the mod on a server.

Who it’s for: Server owners who run survival or creative worlds with large rail systems, and builders who design curved or sloped track layouts.

How it compares

Full comparison

Faster Minecarts is also server-side only and open source under the MIT License, with files for 1.20.1 – 26.1.2, so it covers older game versions than Smooth Minecarts. Flash Carts is server-side only too, but is not open source; it is licensed under Creative Commons Attribution Non Commercial Share Alike 4.0 and targets 1.21.11 – 26.3.

Can the mod be removed from an existing world?

Yes. Uninstalling it restores vanilla minecart mechanics and does not corrupt the world.

What the author says

Great for people who like to build realistic, functional Minecart networks! The mod samples a set number of rails ahead of the minecart, and averages its distance to each rail. This gamerule modifies the number of blocks to sample. You should change this according to how tight your curved track layout is.
