SubwaySim Wiki

This section provides everything you need to build maps for SubwaySim 2 — from creating a new level to preparing and packaging it for use in the game.

You will learn how to:

• create and prepare a level
• migrate assets into your own plugin
• build railway infrastructure using the Railtool
• prepare stations, signals, and AI-relevant data
• define map logic and AI services via Map.lua
• build and test your map in SubwaySim 2

The following chapters guide you step by step through the complete technical map creation workflow.

• Create a Level

Create and prepare a new Unreal Engine level for use with the SubwaySim Modding SDK, including world partition setup and basic configuration.

• Migrate Assets

Safely migrate meshes, materials, and other assets into your own plugin without breaking references.

• Railtool

Build the railway infrastructure of your map.

• Superstructure

Define the physical and visual properties of tracks.

• Laying Tracks

Place track splines, switches, and assign required data layers.

• Importing Switches

Optional step for complex switch constructions.

• Prepare Map

Prepare the level for runtime use in SubwaySim 2:

• validate track layout
• place signals and speed limits
• define stations and platforms

  After this step, the level is technically ready for AI logic.

• Create Map.lua

Define the runtime logic of the map:

• register the map in the ContentManager
• link stations and platforms
• create AI timetables and services
• configure dispatching and depot logic

• Build Mod (.pak)

Package the map into a `.pak` file and test it inside SubwaySim 2.

Editor Tools are used to visually build out and refine the map. They are optional and can be used at any point during development.

Typical use cases include:

• placing platforms and station structures
• adding props and environment details
• refining the visual appearance of stations and depots

Available tools include:

• Prop Placing Tool

Editor Tools do not affect map logic and can be used independently from Map.lua.

Together, these sections cover the full workflow — from an empty level to a finished, playable map in SubwaySim 2.
