How it works
From desktop to the server
The FoundryMTR Launcher handles everything.
Sign in with Microsoft
Authentication happens in the launcher, directly with Microsoft. This website never sees your password.
Click Play
The launcher downloads any updates, starts Minecraft, and connects you to FoundryMTR.
What it is
A server built around its rail network
Survival transit
Gather, build, survive — but the world is organised around the rail network everyone shares.
A shared network
Found stations, extend lines, and connect your builds to the map every other player rides.
MTR-NextGen
The custom transit engine: trains, stations, signalling, route maps, and timetables.
Automatic modpack
The launcher installs Java, Fabric, and the exact mod set — no manual file juggling.
Route map
A public network map of lines, stations, and line colours as the world grows.
Fair infrastructure
Clear rules for shared rail space, signage standards, and coordinated expansion.
The network
Lines, stations, and routes
The public route map will show stations, lines, line colours, and network status as the world is built. Explore the network and how it is run.
