A legitimate does not host pirated content. Instead, it hosts locators (URLs pointing to the original creator’s official site) or alternate KUIDs (suggesting a legally updated version of an asset).
There are generic KUID search engines, such as or the now-defunct TrainzKuidIndex . These are useful, but they are not "exclusive."
When a user searches for a specific KUID (e.g., kuid:12345:67890 ), the results page displays a Traffic Light Status System next to the asset name:
Find newer versions of old files (KUID2) that have been updated for modern versions like TRS19 or Trainz Plus.
The tool will return the name of the asset (e.g., "Generic Track Spline") and the author. Most importantly, it often provides a direct link to the CDP file or the creator's website.
: Always cross-check payware KUIDs with original creators’ stores. Use KUID Finder responsibly to respect asset licensing.
If you are serious about Trainz, find a proven, ethical exclusive finder tool. Support the developers who maintain these databases. Upload your own fixed assets to the DLS. And remember: every KUID you find is a victory.
