About this Mod

Railcraft

Railcraft is a lightweight Minecraft mod for Fabric 1.21.4 that adds a few new rail types with unique properties. Built using modern development tools like Data Generation and Mixin for maintainability and performance.

Note: You must slow down when making turns and going up slopes, if you're going too fast you will derail.

Rails

Wooden Rails – basic, low-cost rails with slower speed.
Lubricated Rails – smoother and slightly faster than standard rails.
Ice Rails / Powered Ice Rails – fast and slippery rails, great for speed-focused builds. (express lines!)

Frequently Asked Questions

Railcraft server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.4). You can switch loaders with one click in the panel.

Is Railcraft compatible with fabric?

Railcraft officially supports fabric for Minecraft 1.21.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Railcraft – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Railcraft consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
