Always create a backup copy of your .cdp file before extracting and modifying its parameters.
Filter your search by "Installed" and sort by "Date of Installation" to find your asset.
Before downloading third-party tools, remember that Trainz’s built-in Content Manager has a built-in extraction workflow.
If you are using a standalone third-party extractor tool, follow these universal steps to safely unpack your assets: trainz cdp extractor
The brain of the asset, containing metadata, names, descriptions, and performance variables.

Older CDP files made for Trainz 2004 or Trainz 2009 might need structural tweaks to work in modern versions like Trainz Railroad Simulator 2019 (TRS19) or Trainz Simulator 22 (TRS22) . Extraction allows you to manually upgrade the asset tags. Method 1: The Built-In Option (Trainz Content Manager) Always create a backup copy of your
Older Trainz assets downloaded from third-party sites often show up as "Faulty" in newer versions of the game like TRS19 or TRS22 due to stricter scripting and formatting rules. By extracting the CDP, you can open the config.txt file manually, fix errors (such as missing tags or incorrect KUID references), and repackage it. 3. File Size and Storage Optimization
: This is a lightweight, "no-installation-necessary" utility. It allows you to search for specific KUIDs within a pack, export asset lists as CSV files, and even customize filename formats for extracted content. You can download the latest version on GitHub .
A .cdp file created for Trainz 2019 might not work in Trainz 2012. Always check that the content is compatible with your version of the game. Best Practices for Managing Custom Content If you are using a standalone third-party extractor
If your goal is to extract a .cdp file to edit its contents, follow this foolproof workflow using the modern native method: Launch Content Manager and import your .cdp file.
When using an extractor to edit content, unless you are creating a "clone" for personal use. If you modify an asset and keep the original KUID, you risk breaking routes that rely on that specific version of the asset. Conclusion
It acts like a .zip or .rar file specifically built to bundle custom content. A single CDP file can contain 3D meshes, textures, sound clips, configuration files ( config.txt ), and script files required for an asset to run in the simulator.
Re-import: Once your edits are done, you can drag the folder back into Content Manager to "Submit" the changes. Best Practices and Safety
