Vehicle Attachment Points

2025-12-15T20:21:52Z

Barn700: /* a.light* (0, 1, etc..) */

These are [[Attachment Points]] in 3D space giving information on various aspects of the train. Attachment Points with these reserved names should be used only for the purposes specified here. You should not attempt to re-use the attachments for other purposes, as behaviours beyond those described here may differ between Trainz builds.

=Special Points=
==a.limfront==
* Marks the front of the train, used for coupling
* Should be roughly the same distance from origin as '''a.limback'''
* Bogeys can be further forward than '''a.limfront''' if desired
* Determines the forward headlight position
* Height above origin (or Z) = 0.89m (2’ 10.8”)

==a.limback==
* Marks the rear of the train, used for coupling
* See '''a.limfront'''
* Height above origin (or Z) = 0.89m (2’ 10.8”)

==a.bog0==
* Front bogey attachment.
* Used for positioning the train on the track.
* Positioned at absolute centre of front bogey.
* Must be on the forward side of the origin (a.limfront side.)
* Must match an actual physical bogey placement that the user can see. This should not be used as a placeholder for non-bogey purposes.

==a.bog1==
* Rear bogey attachment.
* Used for positioning the train on the track.
* Positioned at absolute centre of rear bogey.
* Must be on the rearward side of the origin (a.limback side.)
* Must match an actual physical bogey placement that the user can see. This should not be used as a placeholder for non-bogey purposes.

==a.bog (2, 3, etc)==
* Any other bogey attachments.
* Must match an actual physical bogey placement that the user can see. This should not be used as a placeholder for non-bogey purposes.

==a.exhaust (0, 1, etc..)==
* Smoke generator attachments (where needed.)

==a.ditch* (0, 1, etc..)==
* Ditch lights '''a.ditch0''', '''a.ditch2''' The odd numbered light points flash together, alternating with the even numbered light points.

==a.light* (0, 1, etc..)==

* Attachment points for locomotive headlights.

* These must be numbered consecutively starting with a.light0 which can be at front or rear. Attachments fore of the origin will display when the loco 'heading' is set to forward. Attachments aft of the origin will display when the heading is reversed. For simplicity it's good practise to use e.g. a.light0 and a.light1 at the front and a.light2 and a.light3 at rear though this is not critical as long as they are numbered consecutively.

* For all headlight points (front and rear) the Z axis points toward the loco rear.

* If you only want a light on the rear of the vehicle place a.light0 at the rear.

==a.cabfront==
* Attachment point for the front cabin of a loco.
* Located at the centre of cabin.

==a.cabback==
* Attachment point for the rear cabin of a loco. Use this for dual cab locomotives.
* Located at the centre of cabin
* Front/back cab toggled using the ‘Alt C’ key when using the internal camera mode.

==a.pant (0, 1, etc..)==
* Attachment point for pantographs (where needed, i.e. Electric locos.)

==a.driver (0, 1, etc..)==
* Attachment point for driver mesh (0 is used for the first driver, 1 for the second driver in dual cab for instance.) Currently, only '''a.driver0''' is supported. If this attachment point exists in the mesh but is not used for an attached mesh in the asset's config.txt file, then the driver selected by the user in Driver mode will be placed at this attachment point.

==a.outsideview (0, 1, etc..)==
* These are located external of the loco body mesh.
* The camera is positioned to face the negative Y direction of the attachment.
* Toggled using [ and ] using the internal camera mode after default interior camera views.

==a.r.pivot/a.lever (sample names used only)==
* Special naming convention for attachment points that are to move with the animation of the asset.
* Refer to the CCG for information.

==a.whistle==
* Attachment point for particle effects being emitted when the whistle key is pressed.

==a.couple0==
* Front attachment point for ACS couplers, location is (0,Y,0) where Y is 0.46 metres inboard of "a.limfront".

==a.couple1==
* Rear attachment point for ACS couplers, location is (0,Y,0) where Y is 0.46 metres inboard of "a.limback".

"Bogeys" container

2010-12-06T19:13:02Z

Barn700:

As of classics 3 and later, you can now specify "sideplay-permitted" and "rotation-permitted" in the [["Bogeys" container]].

The default is '0' for sideplay, and '1' for rotation, which matches previous Trainz behaviour. Each is a boolean option (you can set either '0' or '1').

With "sideplay-permitted 1", the bogie will follow the track, rather than stay rigidly locked in place at the location of the attachment point on the body.

With "rotation-permitted 0", the bogie will not rotate to align itself with the track. This is useful when the wheels being represented are fixed to the frame of the vehicle, and are not mounted on a rotating bogie.

For example, a Tri-Bo locomotive where the centre bogie slides from side to side can be represented like this:

bogeys {
0 {
reversed 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
1 {
reversed 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
2 {
reversed 0
sideplay-permitted 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
}

a.bog0 and a.bog1 are used for the two end bogies, and will locate the vehicle on the track as happens now. But the bogie attached at a.bog2 in the middle will now follow the track through curves rather than stay firmly riveted on the underframe with it's wheels dangling in mid air.

Another example is a loco with central power bogies, and outer bogies to help traverse curves. The PRR GG1 (wheel pattern 2-co-co-2) is of this type. This can now be represented as follows:

bogeys {
0 {
reversed 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
1 {
reversed 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
2 {
reversed 0
sideplay-permitted 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
3 {
reversed 1
sideplay-permitted 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
}

a.bog0 and a.bog1 are used for the main power bogies to locate the vehicle correctly on the track. a.bog2 and a.bog3 are used for the leading and trailing unpowered bogies. These are permitted sideplay so they follow the track.

A two axle rigid frame vehicle can be represented as follows:

bogeys {
0 {
reversed 0
rotation-permitted 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
1 {
reversed 1
rotation-permitted 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
}

In this case, each "bogie" would be a single axle. The location of the attachment point will specify how the vehicle is aligned when on a curve, so should be placed at the location of the axle in the 'y' direction.

An interesting case might be a three axle rigid frame vehicle - with sideplay (but no rotation!) on the centre axle. This might be represented as follows:

bogeys {
0 {
reversed 0
rotation-permitted 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
1 {
reversed 0
rotation-permitted 0
bogey <KUID2:xxxxx:yyyyy:zzz>
}
2 {
reversed 0
rotation-permitted 0
sideplay-permitted 1
bogey <KUID2:xxxxx:yyyyy:zzz>
}
}

These tags are useful for steam locos too. Consider the pacific '4-6-2' wheel pattern. Looking from the front (a.limfront) end through to the back (a.limback), one way to arrange the bogie attachment points to get the required behaviour is:

a.bog2 - front bogie (the '4' in '4-6-2'). For best results, the attachment point should be the centre of the wheelbase. Use 'sideplay-permitted 1' on this bogie.

a.bog0 - drive bogie (the '6' in '4-6-2'). The attachment point should be circa where the front axle is. Move it back a bit if you have a lot of axles (e.g. 5 or more) in the drive bogie. Configure this one with 'sideplay-permitted 0' and 'rotation-permitted 0' - you don't want it moving around on curves at all! (With 'rotation-permitted 0' there is now no need to locate it at 0,0,0 to stop it rotating).

a.bog1 - an invisible bogie in line with the rear axle of the drive bogie. Move slightly forward if your drive bogie is large (e.g. 5 axles or more). This will make the locomotive body follow the track properly.

a.bog3 - trailing pony truck (the '2' in '4-6-2'). The attachment point should be in line with axle. Use 'sideplay-permitted 1' as with the front bogie.

This will produce the correct behaviour both from the locomotive body and the various bogies.

Using these parameters should mean that even very flexible locos (e.g. a Mallet or Garratt) can be built in a much more realistic manner, and with fewer separate pieces that need assembly in Surveyor.

===Random debugging hint===

Q: "But I set this feature, and when I go round a corner, my bogie now floats off in some other direction that I wasn't expecting! What is wrong?"

A: Have you by any chance rotated the attachment point by 180 degrees in MAX to get the bogie to appear the other way round, but not set "reversed 1" in the config container for that bogie? These two things together can cause the effect you are seeing. You should also be able to spot this case because your wheels will be rotating the wrong way...
