In this section, we explain how to place and use imported switches in SubwaySim 2 and when they are required.

Imported switches are used whenever the Railtool does not support a specific track layout. Typical examples include:

• double crossovers
• double slip switches
• special or asymmetric switch constructions

Because these layouts can be very complex and highly individual, they are created manually in a 3D application (such as Blender) and then imported into SubwaySim 2 as finished switch assets.

The Railtool supports:

• standard turnouts
• simple crossovers
• regular procedural track geometry

However, some switch types are:

• too complex
• too custom
• or too irregular

to be generated procedurally.

In these cases, imported switches are the intended and correct solution.

SubwaySim 2 already includes a large collection of imported switches used by the base game.

They can be found inside the SubwaySim2_Modding plugin under:

SubwaySim2_Modding / RailwaySystem / ImportedSwitches

This folder contains many ready-made switches that can be used directly in custom maps.

Important:

• Always use the BP_… variants
• Only these Blueprint actors contain the required logic for routing and Railtool integration

To place an imported switch in your level:

• Make sure you are in Selection Mode in the Unreal Editor

(not Railtool mode)

• Navigate to:

SubwaySim2_Modding / RailwaySystem / ImportedSwitches

• Drag the desired BP_ImportedSwitch Blueprint into the level

After placing the switch:

• it can be freely moved
• it can be rotated as needed
• positioning is done manually

Take your time to align the switch correctly with your intended track layout.

Once the switch is placed:

• switch to the Railtool

→ Laying Tracks

• use the Control Points of the imported switch
• connect Railtool track splines to the switch just like normal track elements

After this step:

• the imported switch behaves like any other Railtool-connected track
• AI routing, signaling, and dispatching can work normally

If none of the provided switches fit your needs, you can create your own imported switch.

Typical reasons include:

• unique geometry
• special crossover layouts
• prototype or fictional designs

Creating a custom imported switch involves:

• modeling the switch in a 3D tool (e.g. Blender)
• preparing meshes and pivots correctly
• importing the assets into the SDK
• creating the required Blueprint setup

This process will be explained in the next section.
