Trainz Simulator community, a KUID search is the standard process for identifying and locating specific digital assets (like locomotives, rolling stock, or scenery) or their missing dependencies. What is a KUID? kuid search trainz
(Koolworld User ID) is a unique identifier assigned to every asset in Trainz. Its standard format is
: A unique number chosen by the author for that specific item. Version Number : Optional (in KUID2); tracks updates to the same asset. Methods for KUID Searching 1. Internal Search (Content Manager)
The most direct way to search for assets you already have or that are on the official Download Station (DLS) is through the Content Manager (CM) By Asset ID : Add a filter for "Asset KUID" and enter the full number. By Author ID
: To find all works by a specific creator, set the filter to "Author" and type followed by their User ID (e.g., Finding Missing Dependencies : Right-click an asset and select "List Dependencies"
(or "View Dependencies") to see which KUIDs are required but missing. 2. External Search (Online Databases)
When an asset is not on the DLS (often called "third-party" or "payware"), you must use external search tools: Rememeber to search the internet for missing KUIDS - Trainz
In the world of Trainz Railroad Simulator , the acronym KUID stands for Koolthingz Unique Identifier [15]. It is the DNA of every object in the game, from a single piece of grass to a massive steam locomotive [5]. If you have ever encountered the frustrating "Missing Dependencies" error, mastering the KUID search is the only way to get your routes back on track. 🔍 Understanding KUID Structure
Every KUID follows a specific numerical format that tells the game exactly what the asset is and who made it [5, 11]. kuid:User_ID:Content_ID: The standard format [2]. If a KUID search returns nothing: If you
User_ID: A unique number assigned to every registered Trainz creator [2, 11].
Content_ID: A number chosen by the creator to identify that specific asset [2, 5].
kuid2:User_ID:Content_ID:Version: A newer format that includes a third number at the end to signify an update or revision [11, 15]. 🛠️ How to Perform a KUID Search
When a route is missing parts, it will list "Unknown KUIDs" in your Content Manager. Here is how to find them: 1. In-Game Search (Content Manager)
The first step is always checking the official Download Station (DLS). Open Content Manager. Filter by Asset KUID.
Paste the missing number. If it’s on the DLS, you can right-click and select Download [4]. 2. External Search Databases
Many veteran creators host content on private websites rather than the official DLS. If the Content Manager fails, use these community-trusted search tools:
Trainz KUID Index: A massive database that indexes assets from various third-party sites [1]. Include the exact KUID and the name of the route/locomotive
KUID Base (Trainz-MP): A popular search tool often used for finding Eastern European and Russian assets [30]. 3. The "Google Method"
If specialized databases come up empty, simply paste the full KUID (including the brackets and colons, e.g., ) into a search engine [4]. This often leads to forum threads where other users have shared links to the original creator's website [1, 16]. 💡 Pro Tips for Missing Assets
Identify the Author: You can search for all assets by a specific creator by using the Author filter in Content Manager followed by their User_ID [18].
Check Payware: Some missing KUIDs are part of built-in routes or paid DLC [17]. If a KUID starts with a specific range, it may be "built-in" content you haven't installed yet [19].
The "Orange Block" Trick: If you absolutely cannot find a KUID, you can create a "dummy" asset with that same number. This will place a placeholder (like a colorful block) in your route so you can see where the object was supposed to be and replace it with something else [13].
| 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. |
Before diving into search techniques, let’s break down the anatomy of a KUID.
A standard KUID looks like: <kuid:123456:100001>
Sometimes you’ll see a KUID2, which includes a version number: <kuid2:123456:100001:3>. The :3 means version 3 of that asset.
