KIND Engine assets are classified as rolling stock which contain diesel or electric loco engine performance characteristics. The related sister-KIND or class asset is kind steam-engine which uses many if not all of the same (sub-)containers or Child classes listed below, but has a different pallet of base data which needs be modeled and defined in the parent class (i.e. the container 'KIND Engine'—those tags and special KIND containers discussed here below). This modular breakout should make working with configs easier for the new and old Trainzers to get a handle on.  

Historical engine-specs

Formats of engine specifications evolved from the earliest Trainz versions, perhaps more than any other digital modeling group of assets, which is readily understandable given the dependency of a locomotive's driving behavior (the physical reality modeled and simulated in a digital virtual world) depend more than any other class of object on tight interaction between scripting, animation elements, and the physics model within Trainz. Unfortunately, the older Content Creator's Guides (early era, HTML pages and files, after UTC as *.pdf files) were also generally kept online for ease of updating, and cannot now*[notes 1] be readily accessed by new comers or others interested in comparing different digital models.
If these are of interest—especially if you have ambitions to become a Loco CC maker and want to study the old vs. the new, make pals with someone who has the older versions downloaded and will share. Better yet, lurk on eBay and such other consumer to consumer retail sites and acquire the older Trainz versions.

The containers and gross changes in engine-specs may be compared to the current grouping of tags and containers by seeing the CCGTC Online page: Kind: Engine.

KINDs (type asset groups)
and containers


Parent Classes

TrainzBaseSpec

Child Classes-containers

The engine child data structures are termed containers in Trainz and each defines the parameters and variables the simulator software needs to produce a dynamic working 3D asset.

  1. throttle-power container
  2. dynamic-brake container
  3. pressure container
  4. mass container
  5. motor container
  6. flowsize container
  7. volume container

  • Corrective action: Move into description block text or delete line.

autopilot-stop-distance

Type: float
Desc: How far (in meters) in front of a typical obstruction (red light, etc.) the AI will attempt to stop the train. Changing this value can help fine-tune the accuracy of the AI's movement, however attempting to make the train stop too close to a target may result in overruns in some cases. This tag is intended for special-case usage only.

autopilot-crawl-distance

Type: float
Desc: Once this distance (in meters) from the intended stopping position has been reached, the AI will 'crawl' rather than attempt to speed up to reach its destination. Changing this value can help fine-tune the accuracy of the AI's movement, however attempting to make the train stop too close to a target may result in overruns in some cases. This tag is intended for special-case usage only.

autopilot-caution-speed-multiplier

Type: float
Desc: The AI will slow to this multiple of the speed limit when operating under caution conditions. This can be set to 1.0 in order to effectively remove caution-speed driving, however this can increase the risk of overruns in some cases

throttle-adjustment-rate

Type: float
Desc: Defines the adjustment rate at which the engine's throttle will adjust to match the train's throttle. Increasing this rate will make the engine more responsive at the possible cost of audio or driving realism. In DCC mode, a minimum value of 0.1 is used.
