Description

This repository ports Create: Steam 'n' Rails to the latest public version of Create Fly for stable Minecraft 26.2. Steam 'n' Rails expands Create's train and steam systems with custom tracks, semaphores, conductors, bogeys, palettes, and other railway content.

Compatibility

Component Required version Minecraft 26.2 exactly Mod loader Fabric Loader 0.19.3 or newer Fabric API 0.152.0+26.2 or newer Create Create Fly 6.0.9-1 or newer Java 25 This port 1.7.2-fly.26.2-beta.1

This is a Fabric-only port. Forge and NeoForge are not supported. Use Create Fly rather than another Create implementation, and do not install the original Steam 'n' Rails JAR alongside this port.

Installation

Install Java 25, Fabric Loader, and Fabric API for Minecraft 26.2.
Install the latest public Create Fly build compatible with Minecraft 26.2.
Put this port's non-sources JAR in the instance's mods directory.
Start the game and confirm that Fabric reports railways, create, and their dependencies as loaded.

Back up existing worlds before opening them with a beta port or a new Minecraft version.

Port status

The port is currently in beta. The main mod is playable, but optional third-party integrations and development/datagen paths inherited from the upstream 1.20.x project are not all validated on 26.2.

Recent Create Fly compatibility work includes:

enforcing bogey gauge compatibility when placing or cycling bogeys;
restoring curved monorail geometry and monorail-specific selection outlines;
fixing track-switch rendering, rail overlays, flickering, and related crashes;
preventing animated locometal flywheels from rendering a second static wheel.

When reporting a problem, include the complete latest.log or crash report, a short reproduction sequence, and whether the issue also occurs with only Steam 'n' Rails and its required dependencies installed.

Building from source

The project uses the included Gradle wrapper and requires JDK 25. Set JAVA_HOME to that JDK before building.

Windows PowerShell:

./gradlew.bat clean build validateAccessWidener --no-daemon

Linux or macOS:

./gradlew clean build validateAccessWidener --no-daemon

The distributable JAR is written to build/libs/. Use the JAR without the -sources suffix. The first build also downloads the development dependencies and generates the connected-texture sprites used by this port.

Datagen

For maintainer datagen tasks, set the following environment variable before running the relevant Gradle task:

DATAGEN=TRUE
