I understand you’re looking for a proper paper on the — a tool used to convert between various Trainz asset formats (e.g., .cdp, .cdp2, .cdpa, .texture, etc.).
After editing the config.txt , right-click and "Submit Changes."
If a conversion tool throws an error, the file may have downloaded incorrectly. Try redownloading the CDP file or checking if it was compressed into a .zip archive first.

Extracts all assets from a .cdp/.cdp2/.cdpa to a folder, preserving folder structure and asset KUIDs. trainz cdp converter
Commercial add-ons (Payware) from N3V Games or third-party developers are heavily encrypted. Attempting to use a third-party converter to crack open these files violates the game's End User License Agreement (EULA) and can result in account bans. Conclusion
A simple utility to convert Trainz .cdp (compressed session/package) files into usable asset folders or repackage assets into .cdp for distribution, preserving metadata and dependencies.
: This is a highly-rated utility that acts like a "zip" reader for CDP files. It allows you to: View contents of a CDP before installing them in-game.
: You cannot directly convert a CDP file into a 3D model (like .obj or .fbx) for external editing. CDP files are compressed data packs, not 3D source files. I understand you’re looking for a proper paper
It converts locked Trainz .texture files into editable .tga or .bmp image files.
An older command-line utility provided by N3V Games in legacy versions (like TS2009 and TS12) that allowed bulk unpacking via command prompts.
| ⚠️ Issue | Explanation | |----------|-------------| | | The converter does not verify if an asset’s trainz-build tag matches the target Trainz version. You may still need to update config.txt manually. | | Asset dependencies | Extracting a CDP does not automatically extract dependencies (e.g., a locomotive’s sound or cabview). You must convert those separately. | | Copyright & distribution | Converting someone else’s paid/freeware asset for repackaging without permission violates most Trainz content licenses. Only use on your own work or with explicit permission. | | Corruption risk | Always keep backups. An incomplete or incorrectly converted CDP may cause Trainz to crash. | | No macOS/Linux version | Works only on Windows. Linux/macOS users can try Wine, but results vary. |
