Start guide

What it recreates

Recreates Locomotion using the original graphics, music and sound files. OpenTTD and OpenRCT2 are separate projects.

What’s different

Adds track blueprints, improved zoom and interface controls, and OpenGraphics replacement objects. Multiplayer is not yet available.

What you can use today

v26.09 offers Windows 32/64-bit ZIPs, a Linux x86-64 AppImage and a native macOS arm64 app. The Mac download requires Apple silicon and is unsigned and unnotarized. RemakeList has not run these builds.
