The first set of numbers identifies the specific creator who made the asset. Every registered Trainz user has a unique UserID.
Used in KUID2 to indicate updates. Higher numbers automatically overwrite older versions. Why You Need to Search for KUIDs
If you know the creator's UserNumber, filter your search by "Author" to see if the asset is packed inside a larger dependency pack. Step 2: Leverage Dedicated KUID Search Engines kuid search trainz

Sometimes you will see a KUID2 format, which looks like this: KUID2:User ID:Content ID:Version (e.g., KUID2:123456:78910:1 ). The final number indicates the version of the asset. Trainz automatically prioritizes the highest version number available. Step 1: Identifying Your Missing KUIDs
| Challenge | Explanation | |-----------|-------------| | | Asset has been replaced by a newer version; original KUID no longer exists. | | Payware/Third-party only | KUID is not on DLS; must purchase or download from creator’s site. | | Missing version suffix | Searching for :1 may fail if the current version is :3 . | | Author ID changed | Some creators re-upload under new account; original KUID becomes orphaned. | | Case sensitivity | Not typically an issue, but some external databases treat KUIDs as case-sensitive strings. | | Faulty or corrupted assets | KUID exists but asset has errors preventing use. |
Before diving into the search process, it helps to understand what you are actually looking for. KUID stands for (a legacy name from the original developers of the simulator engine). Every route, session, locomotive, rolling stock, tree, track segment, and sound file has its own unique KUID.

A KUID (or "KUID Index") is a unique alphanumeric identifier assigned to every single asset in the Trainz database—whether it is a locomotive, a tree, or a section of track. Think of it as a Social Security number for that specific file.
This is the gold standard for independent Trainz asset hunting. It is a massive, community-maintained database that crawls independent Trainz websites globally.
If you have spent any time in the Trainz Railroad Simulator ecosystem, you have inevitably run into a missing dependency error. Your routes are full of empty space, your locomotives are invisible, and the Content Manager is flashing red warnings.
A standard KUID looks like this: KUID:User ID:Content ID A newer version (KUID2) looks like this: KUID2:User ID:Content ID:Version Number
