🚂 How to Install a .RWP File in Train Simulator Classic
 
✅ Step 1: Locate the Utilities.exe tool
Go to the folder where Train Simulator Classic is installed.
By default, it is usually located at:
C:\Program Files (x86)\Steam\steamapps\common\RailWorks
Inside that folder, open the Utilities.exe file (this is the official content manager for TS Classic).
✅ Step 2: Install the .RWP file
In the Utilities.exe window, click the “Package Manager” tab.
Click “Install” at the bottom right.
A file browser window will appear — find and select the .RWP file you downloaded (e.g., TGM8km.rwp).
Click “Open” and wait for the installation to complete.
You’ll see the new content added to the list once it's installed.
✅ Step 3: Activate the Asset in the Scenario Editor
Launch Train Simulator Classic normally.
Go to Build > Scenario Editor or open an existing route in Editor mode.
On the right-hand side, click the blue cube icon (this is the Object Set Filter).
A list of developers/publishers will appear. Look for the name used in your RWP package.
For example:
Developer: CubaTrainSim
Product: TGM8km
(The exact names may vary depending on how the Asset was packaged.)
Check the box next to it to activate that Asset set.
You can now find the TGM8km locomotive and place it in your scenario using the left-side object browser (vehicles tab).
 
🛠️ Optional: Quick Drive
If the RWP includes Quick Drive consists, go to the Drive menu > Quick Drive, and check if the TGM8km appears in the locomotive selection dropdown.
 
❓ Having Issues?
Make sure you installed the .RWP with Utilities.exe, not just unzipped it.
Double-check the Asset folder structure if it's not appearing.
If needed, restart the game after installation.
