Trainz Notations[edit]

This special glossary page will assist the new reader in getting the gist of Trainz-speak. It is a terse set of other terms that are usually more fully elaborated on in the Glossary and at times, given topic pages all their own for in depth exposition.

Keypress notations[edit]

Many Trainz functions are accessed using the mouse or hotkeys. The later change depending upon which module of the software suite is active, though commonality of purpose is preserved from application to application when there is overlap. Mostly there isn't.

Standard Abbreviations[edit]

  • in this book —means may see elsewhere, but this is what is meant here.
  • general shorthand —means seen often on the web forums too.
  • Kc:, Kd:, Ks: Keys, usu. Hotkeys respectively in CM, Driver (DVR) or Surveyor (SUR)

Terms and Acronyms[edit]


Term Meaning Comments, clarifications, or notes
  ..\pathspec    path from
reference folder 
 usually used to signify a sub-folder (the 'local root directory') of the Trainz install directory so '..\TS12\bin and '..\bin would mean the same in usage context.
'..\TS12' means what ever the '..'=initial_pathspec is the way you installed Trainz (i.e. where TS12 is installed on your computer). See also pathspec and namespec below.
  ALCO        American Locomotive Company - a popular locomotives - engine manufacturer, many designs of which have been subsequently used as prototypes for digital and physical Model Railroading models.
  Asset-X        Freeware asset fixing tool when used with TARDIS scripts to update and fix assets in conjunction with PEVtools freeware.
  baggage car        when rails were king, luggage and freight carrying cars.

  Built-in asset
  or (BI)  
  or Built-ins   All the built-in items of your Trainz release version. These are found in .JA files which are configured for rapid upload into the game and tightly organized. Certain items, such as thumbnails are stripped from the JA's which are mandatory for uploading an asset to the DLS, where the thumbnails are used in web pages and/or downloaded to the cache for views in CM. Consequently, such images are not part of any cloned asset.
  CAB file    compressed Asset Base
 or CABinet files 
 CAB files are a software term of art for a library of files that may be and usually are options in the install. Microsoft Windows and many other applications allow user customization by adding or deleting components, such as Microsoft Media Player, accessibility assets like magnifiers, internationalization customizations for languages, audio text readers for the hearing impaired, and even system utilities like disk maintenance applications. Trainz CAB file analog is the JA files, which contain all the installs' base assets distributed with the specific retail release.
  carriage        a popular prototyped passenger traincars - usu. by a manufacturer
  CC or
 Content Creators   Those wonderful people that freely give a great deal of time and painstaking devotion to providing digital models for Trainz.
 These are: Route builders, Asset makers, Scripting specialists and Session writer's—which activities take a big chunk of time and they ought be appreciated for fueling Trainz for over a decade now.
  CM    Content Manager Utility data manager, Trainz Windows application to download, upload, archive, sort, and manipulate assets, including cloning and editing. CMP became 'CM 2.0' in TRS2009, and then CM 3.3 later in it's 4th service pack - since that upgrade, all CMs display the new asset Trainz-build version (v#.#) in the title bar.
  CMP    Content Manager Plus   Older initial all in one CM Windows application introduced in v1.5 and up versions of TRS2006 and the 3 Trainz Classics.
  CSAR    Computing  term  Conditional Search and Replace. See SAR in the glossary for details and distinctions.
  depreciated    especially depreciated tag or keyword    A depreciated practice or definition is one set aside and abandoned in future formulations. N3V's programmer's most often mis-characterize such swerves in acceptable practice as "obsolete"—which itself should more correctly be termed as obsolescent (equivalent to depreciated), for both are still valid for older content definitions. To be obsolete, the practice or keyword would NEVER have correct scope or place; a subtle but important distinction. One can fix many an asset successfully by satisfying now obsolescent standards (perhaps by gradually even successively incrementing the trainz-build and addressing and repairing new warnings and errors) to a lower than current trainz-build your installed CM can translate. In contrast, one can arrest such successive fix ups at a lower than current version trainz-build and locally have a perfectly good asset. It just can't be uploaded to the DLS which has input screening which enforces stricter standards than your current Content Manager.
  EDR    Extended database repair   Selecting EDR from the CM ALT+F7 hotkey or options menu launches the big brother of the QDR, which forces a full thorough database self-audit, including checking installed assets, and record like ..UserData\Originals, backups and etcetera.
  • It takes quite a while as a result, so if tempted, make sure you have no plans for the computer for up to half a day; comparatively the EDR takes a much greater time, even with no added content on a system, for it not only rebuilds the assets.tdx index file but also rechecks validity of content, looking for faults.

In particular, disable anti-virus and Mal-ware checking and especially disable any auto updates which might reboot the system with disastrous results to Trainz. Best run overnight, verify your scheduler apps don't interrupt and that your scanning security utilities are disabled--the EDR is internal, and no scanning of files is in any ways useful, but just slow things down stealing resources and processor cycles from Trainz--which will be pushing your processor to the limits!.

  • [Ed-note:' Disabling internet connectivity has been reported to speed the process considerably.]Ø
  EMD        a popular prototyped locomotives - engine manufactured by General Motors Electromotor Division
  Error Fixing        Process, usually of running PEVtools to update some extractable data types and upgrade an asset with concurrent edits to the assets config.txt files.
  enumerated    strictly
 Enumerated types strictly define legal values, and proscribe undefinable values, which generate an error. category-region tag TAGS and category-classes are data fields which must satisfy enumerated values checks. Boolean values must only be a 1 or 0, or similarly generate errors.
  filenamespec     Operating
system path  
 reference to folders hierarchy in Windows; C:\TS12\UserData\editing\$dummyScreenshot.jpg for example has a pathspec, a filename and is when all together a 'filenamespec' combining both.


Term Meaning Comments, clarifications, or notes
  Any Trainz
code build  
 Each or any Trainz version on a particular computer and it's Hard drives in it's own local root folder. This author has a version for each hotfix and Service Pack of each Retail release version since TS09-SP1 and each are an 'install' since SP2, SP3 and SP4 all differ. Repeat as needed for TS10 and TS12!
 instance or
 an occurrence of something...  In computer science a selection specification of several possibilities
 usually in Trainz a product amount by class of product. e.g. a flat car might hold upto seven pallets of general goods; each being an instance of general goods in one instance of it's queues container—where the second usage refers to a choice in model construction of several different queue product types which might be enabled for that traincar.[1]
  GUI    Jargon: 'Graphical User Interface'   The three 'run-time' module we can view the Trainz virtual world or models within. They are Driver, Railyard, and Surveyor. (Content Manager is a Windows application, as some would argue are the Loader, Launcher, and Main Menus screens.) Technically all are GUIs, but control is either Trainz or Windows, so there is a teensy-tiny distinction.
  keyword    computing term   A 'Reserved word' meaning enumerated and given special scope and legal use. containers, kinds and tags are all keyword enumerated types which signify particular handling when processing their data value fields.
Abbrv: HKey  
 A Hotkey in computing is also known as a keyboard shortcut, and are usually a Key-press combination where multiple keys are pressed at the same moment, or a Operations key that is built into the software and changes or accesses some other mode. One 'almost' universal sequence ALT+F+something in Windows Apps will bring you to the File drop down menu to Save..., save As..., Open, etcetera. So Hokey gives FILES (a mode change, launch mode entry to file operations). Another two well used: Win+E - Opens Windows Explorer; ESC suspends browser page build operationa... canceling loading that link you really didn't mean to click.
 JA file  Compressed Asset Base file type   The standard Auran Compressed Asset Base (CAB file), which includes all the built-in items of your Trainz release version. JA files are configured for rapid upload into the game and tightly organized. They may be ported version to version within certain limitations. TS09 JAs, TS10 JAs can be added to TS12's bag of tricks. TANE is expected to have similar capability, otherwise route and session assets that took many man-months to create would not be forward-compatible, a hallmark of Trainz since its earliest days.
See also: Trainz/file types by extensions
 kuid reference or 
 referenced kuid
  enumerated data type   KUIDs data field of a tag listing a sub-asset (dependency) used to build the current asset in a config.txt file tag or container. Specific data key-words (tags) will specify a kuid reference, which must then also be listed in the asset's kuid-table (identifying independent asset dependencies).
  image file     graphics files   data in image form, Trainz handles BMP, JPG, TGA, and GIF image file types. For others, see File formats
  mail car     A class of rolling stock    when rails were king, valuables and small freight (Sears and Roebuck Mail-orders!) carrying cars commonly the target of robbers like Jesse James and his crew, since they frequently carried money or bullion!
  minimap    Ks: CTRL+M 
 Kd: M 
 In Surveyor, opens a map less than full screen size that one normally sizes and positions in the lower LH corner as preferred using LMBHd. It shows the surroundings from the centered-cursor/camera position, and a key feature is it selectively allows one to see labels not otherwise displayable in Surveyor or Driver (e.g. Names of triggers) Alternatively, also M in Driver, only.


Term Meaning Comments, clarifications, or notes
  NAMCON    naming convention   Naming conventions are just guidelines as to how a name is formatted. Is it better to make a username of the form: 'PRR 40' Boxcar' or 'Boxcar, 40ft PRR'? These vary CC to CC, and within any organization producing co-operative output.

  named parameter
 or explicit parameter 
     A name in scripting encoding and decoding languages (such as wikimarkup language which builds this page) which has limited scope and which is a specific temporary keyword in passing a value to another process. Both the passing routine and the deciphering or called code must evaluate the term the same, and such parameters are case sensitive. The analog in general computing is a variable which must be declared of a specific type. In the scripting application, the typing is handled solely by context and interpretation, while in the compiled computer languages, the typing corresponds to allocation of physical memory and the typing also constrains the types of operations allowed on the data.
  pass parameter        A computing software term referring to sending a value into another part of the software as an input, normally a function or module which then further processes the passed data.
alt: PEV-tools   general use, Asset updating freeware suite that in later Trainz can fix many error conditions, generate shadow meshes and convert old fashioned v1.x PM to IM mesh files. See Setting up PEVtools and PEVtools pages.
 placeholder parameter or
 dummy parameter or
 dummy keyword 
 computing term
 A dummy or placeholder is a reference made in a sequential order, so one who's data is evaluated in that 'place' in a 'read order'. Many Trainz containers and especially Trainz's sub-containers defining data for initializing an array are placeholders usually represented by the set {Ph: 1, 2, 3, ..., nn}, for all trainz data definitions values are pairs of the form 'keyword' (whitespace) 'Data'.
  QDR    Quick Database Repair   Selecting QDR from the CM ALT+F7 hotkey or options menu launches the little brother of the Extended Data Base repair, which forces a quick partial database self-audit, including cross-checking installed assets, filenames, and inventory check it's references to the record like ..UserData\Originals, backups and etcetera.
  • It takes a short while (10-30 minutes) but may reconnect files in Assets.tdx, 'open for edit' or those you may have added in other folders as a result; comparatively the EDR takes a much greater time, even with no added content on a system.
 Asset Root
 asset's root or
 asset's root
 local Install's ..\editing subfolder of any Trainz installation usually where Content Manager opens a sub-folder in the Trainz' Installation's ../editing sub-folder;
or sometimes means a users or CC's archived source folder before importing it into his uploader CM Installation.
In each case the folder defining all of that asset.
Note: Many veteran Trainzer's, esp. CCs keep a second (backup) or third (plain jane) Trainz install to test dependencies on a 'bare' version before uploading.
 Root folder
 local root or
local root folder
  Installed subfolder of an
hard drive  
 Where you let the installer software put a Trainz version when adding the software to your computer. Conventions were C:\Auran\subfolder and later C:\N3V, or D or F hard drives (HDD) with like names. Some put Installs directly off the root of the HDD such as for example: 'F:\$TS12-SP1+hf3' or 'D:\TS09-SP2' , both actual folders on this computer at the moment!)
Hot user tip: Putting Windows and Trainz versions on the same HDD will slow things down, as will installs on the same HDD as the Windows TEMP (cache folders) directory.
  pathspec     Operating
system path  
 reference to folders hierarchy in Windows; C:\TS12\UserData\editing\$dummyScreenshot.jpg for example has a pathspec, a filename and is when all together a 'filenamespec' combining both.
 fm SAR 
Term (Jargon) 
 lit.:Conditional Search and Replace and Search and Replace, (aka, 'Find and Replace'); variant GSAR=Global Search and Replace (all or nothing, more risky that you may change something you shouldn't than one by one. Use REGEX to narrow risk significantly.
 Set notation
{xxx: val-0, val-1, val-2, ..., val-nn}  
 list of 'xxx' typed things are:... values list   example: {tag: category-era-0, category-era-1, category-era-2, ...}
  String array    Wikibook term
special container
 data class name 
 Several Trainz legacy tags or keyword's which had numeric suffixes for each declaration have been superceded by defining those values within a quoted string and delimiting (separating) them from the next by use of a semicolon ';' . (See name-xx, category-region-xx, category-era-xx etc. versus username-xx explanations.)
  structure or
 data structure 
 data structure   A computer science term referring to the way data is organized internally in a piece of computer software. Trainz containers and Kinds are higher level Trainz data structures, while simple tags TAGS are simple keyword-value paired data values with proscribed enumerated keywords, having a corresponding 'key meaning' in the self-definition of a digital model (Assets).


Term Meaning Comments, clarifications, or notes
  TAD    Trainz Assets
 Where all the goodies bundled or off the web are kept in your Trainz Installation to feed CM, Driver, Surveyor and Railyard. Today's Trainz run a program called TADdaemon in the background to handle multi-tasking activities, including internet interactive gaming.
  TADdaemon    TAD + daemon   A Database transactions manager added to Trainz in TS09-SP4 and the TS10's.
 • The most important thing to know about TADdaemon is you need to give it 30-45 seconds (to finish it's bookkeeping needs) and completely shut down after closing any Trainz install completely—and esp. before rebooting or powering down the computer![note 1]
 • The second, is that if still active, that 30+ seconds long window is designed to give you time to quit CM and Launch the run-time GUI's, in which case Trainz has a handle on the current database state and will load much faster
 English jargon: something unsettled yet   lit. To Be Determined or To Be Determined Later, this later form carrying the connotation the tabling of some issue or feature is both by design and intent.
 • Many societies, whether they be business, government, or social, know the best way to eat an Elephant is one bite at at time.
Starting is half-done is a truism in allocating scarce time resources, and many decisions can be deferred (such as what might go into blank lines on this table) until a fuller picture of needs is determined.
  TBS    The TrainzBaseSpec   Fundamental parent data defines of any asset KIND which every self-defining asset or element needs to bootstrap itself in Trainz. The TBS contains the set of defines which are common to and legal in all assets.
 {{Trainz CC}}
or TCC  
+ 'Trainz Routes'
 Formal retail release name of Trainz Complete Collection, ca. 2006 — an omnibus 3CD collection with TRS2004-SP4, TRS2006-SP1 and Trainz Routes (extra content CD).

  TLC    American slang   lit. Tender Loving Care—here in the TWB, generally meaning or referring to: 'something' (an asset, usu. a route or session) which needs a lot more work to be acceptably up to the societies grade and standards!
 • A corollary: Don't put things up on the DLS which aren't up to snuff! Share things you are proud of while learning with Dropbox or other cloud services, but don't stress the communities patience with you, nor damage your reputation with premature uploads of junk!
  TLCP       in this book, shorthand for the controversial and user community disliked Trainz_Life-Cycle_Policy, or at least the heavy-handed implementation of it requiring assets being uploaded to conform to a higher trainz-build level than necessarily (formerly a tech-level tracking system, now perverted to become a retailing tool) needed by the asset's configuration and component parts have need of. Many if not most assets, not requiring or using a tiddly change in the Trainz script libraries, the data models work fine with much lower TB values. Auran/N3V is merely hoping to force people to upgrade to newer generation Trainz releases—so dictating they must buy new computers and video regardless of age, financial circumstances and personal choices.
         in this book, shorthand
  Trainz 1.x    Trainz 1.3   The 2001 simulator which wouldn't quit despite Microsoft's wishes. Surveyor is the tool that makes Trainz special and the versions today look much the same with some different skins/themes and a few improved Surveyor tools options like layers, Pick lists and other incremental changes.
         in this book, shorthand TBD
  Trainz UTC     Trainz UTC    formal release name of 'UTC', Trainz: Ultimate Trainz Collection, version bundled and upgraded Trainz 1.3, with scenarios introducing TrainzScript and some extra routes and content.

Term Meaning Comments, clarifications, or notes
 unary value  
 Math and computing term   A unary (lit. from Latin: un+ary), is a single term, or a parameter (variable) "consisting of, or affecting, a single element or component; monadic "[4] as opposed to binary, trinary, or quadary elements. Even placeholder parameters in Trainz are always binary operators, a tag and a value. Pass parameters in Wikimarkup templates although placeholders or named parameters, are always unary--they have only the one part.[5]
  UTC    Trainz v1.5 Ultimate Trainz Collection   general shorthand for the important version that introduced scripting in Trainz, which in TRS2004 gave Trainz interactive railcars and industries.

Notes and Footnotes[edit]


  1. As a transactions manager TADdaemon also allows one to run CM and even multiple times the same CM safely whilst Driving or running Surveyor!
     • The CM's filter tabs will 'interact' and have a mild conflict, but if one sets a static filter up on the first, and a different filter up on the second, Surveyor and the CM's co-exist quite handily.[2] (Just don't count on that first CM's 'Current Search' to be unchanged if you refresh!)
