Part 5: Step-by-Step Guide – Getting the Work Done Right

Let’s assume you have a faulty locomotive CDP named Big_Boy_4014.cdp. Here is the foolproof workflow for extraction:

  1. Download CDP Explorer v2.0.8.1 or higher (or locate your bin folder for TrainzUtil).
  2. Create a new folder on your desktop: C:\CDP_Work.
  3. Option A (GUI): Launch CDP Explorer. Drag Big_Boy_4014.cdp into the window. You will see a tree of files. Select config.txt and click "Export Selected."
  4. Option B (Command Line): Press Win+R, type cmd, navigate to C:\Program Files\N3V Games\TRS22\bin. Type: trainzutil extract C:\Downloads\Big_Boy_4014.cdp C:\CDP_Work
  5. Result: You will now find a folder named Big_Boy_4014 inside C:\CDP_Work containing the raw, editable asset files.

Crucial tip for modders: Never edit the CDP file directly. An extractor creates a copy. Keep the original CDP as a backup.

  2. Click File > Import CDP and select your file. It will now appear in the main list.
