KUID search is not optional in Trainz – it is the fundamental skill for content management. Mastering the built-in Content Manager search, the DLS website, and external KUID indexes will solve over 95% of missing asset issues. For the remaining edge cases, community forums and direct file inspection remain reliable fallbacks.
“A missing KUID is not a dead end – it’s just a starting point for search.”

Trainz Simulator (Kooler User ID) is a unique identification number assigned to every asset—from locomotives to blades of grass—ensuring the game can locate and load the correct files. Finding missing KUIDs, often called "dependencies," is a common task for players downloading custom routes or trains. 1. Understanding the KUID Format A KUID consists of three main parts, typically formatted as
to indicate updates; higher numbers automatically override older ones in the game. 2. Searching within Trainz Content Manager The built-in Content Manager (CM)
is your first tool for locating assets already on your computer or the official Download Station (DLS). Direct KUID Search:
Use the search bar or filters. In newer versions like Trainz 2019/2022, click the arrow, select Asset KUID , and paste the full KUID. Listing Dependencies: kuid search trainz
If an asset shows a "Missing Dependencies" icon (a yellow puzzle piece), right-click it and select List Dependencies Downloading from DLS:
Items marked as "Available for download" can be right-clicked and downloaded directly within CM. 3. Searching for "Unknown" KUIDs Online
If an asset is marked as "Unknown," it is likely hosted on a third-party website rather than the DLS. Use these specialized search engines to find them: HowTo/Finding Missing Dependencies - TrainzOnline
The easiest and safest place to find a KUID is the official Download Station (DLS). This is N3V Games’ central repository for thousands of assets.
How to do it:
What happens next:
Pro Tip: If you are using T:ANE or TRS22, ensure you are logged into your MyTrainz account. Without an active First Class Ticket (FCT), DLS downloads are throttled to slow speeds, but the search function still works perfectly.
For the advanced user, the real power lies in third-party "KUID Portals." The most famous of these is the Trainz Dependency Walker or sites like **Trainz.Mons.
Content Manager is the asset management hub in every modern version of Trainz.
Step-by-step:
What happens next:
Pro tip: Use the Status filter. Click the dropdown and choose Missing Dependencies. Then sort by KUID. This shows all missing KUIDS for a selected route or locomotive. KUID search is not optional in Trainz –
| Tool | Function |
|------|----------|
| TrainzUtil (command line) | trainzutil findasset <kuid> – returns location/status. |
| CDP Explorer (third-party) | Opens .cdp files to list contained KUIDs without importing to Trainz. |
| KUID browser extensions (Firefox/Chrome) | None widely maintained; use custom search shortcuts. |
The final step in any exhaustive KUID search trainz journey is human interaction. The Trainz community is older, dedicated, and incredibly helpful.
Etiquette Guide: When asking for help, do not just post Help I need kuid:123:456. Instead, post:
"Looking for kuid:123:456 (Auran Jet Engine sound). Checked DLS and TrainzKUIDIndex, no luck. Running TRS22. Any help appreciated?"
This shows you have done your homework, and people will respect that.
