I became slightly confused today. There are parts that I pulled off your website many years ago. Now it seems as if they don’t exist. They are parts for the Train Track 9v Points. They were authored by Soete Ludo. I submitted one thinking it was an update. Only it was treated as if I authored it. Could you please explain?
This is the part list:
2864.dat
2866.dat
s\2864s01.dat

Sorry, what 'your website' do you mean? And what did you mean by 'submitted'.

I'm really quite at a loss to understand what you mean here.

I assume I got them from the Parts Tracker. But now there is no reference of them.

They might come from Tomas Burgers BS folder here.

In that folder are also two partnumbers that might be relevant here.
53404/53407, switch right/left, but I can also find numbers 53403/53406 as switch right/left.
I think that it is part alias numbers.

Maybe you got them from LUGNET
2864, 2866, s/2864s01
and they were never submitted to the LDraw Parts Tracker

Ludo Soete has affirmed the contributor agreement so if you wish to leave him as the original author you should set the author line to:

Now I just noticed that things have gotten a little complicated with the parts 2859 and 2861. It seems an author/reviewer has submitted other versions of these parts. And when I submit my updates. The submission is changed somehow.

My main goal is to get these parts certified. I don’t care who gets the credit. So if you can narrow down what needs to be what? I will do my best to fix it. I can understand simple fixes, but this is blown out of proportion.

It is not like these file just popped up last week. They have been in the Parts Tracker since 2009.

And thank you for the answer to my first question. I thought I was going nuts.

They way in which we handle these complex assemblies has changed over the years. The current thinking is to publish each separate moulding as a LDraw "Part", but to prefix the description with "~" if it is not a part that is issued separately by LEGO. In many cases we don't know (and maybe will never know) the design number for these moulding, so thet get allocated a Unnnn number.

Subparts should only be used for repeated or reusable sections of a "Part". A pertinent example is for sections of a part that may be used in mirror-image form in another part - but to allow stud substitution by renderers that include the LEGO logo, studs should not be included in such subparts, but rather placed in the parent part file.

The issued assembly is normally nnnnC01, where nnnn is the design number of the largest or most obvious "Part". Sometime we know the LEGO number for the assembly.

I can rename and renumber as Admin, so please give me a day or so to straighten this out, then we can assess what remains to be done.

Chris,

All sub-part codes are known for these parts. Keep me in the loop, please.

Please post those as comments on the Parts Tracker, to avoid me renaming twice.

Ugh. The original LUGNET post had all the right numbers (except the two he didn't know for the left-hand version). I'll dig through and see what I can do...

Do you mean this? In which case I think we still need answers to:

Quote:2) I still need part numbers from the lefthand point. I need the part number
of the LEFTHAND point tongue and the LEFTHAND point bottom plate. All other
parts - point tongue command rod & yellow lever - are identical.

We now know:
LEFTHAND point tongue = 2862
LEFTHAND point bottom plate = 2939.

Hello Kevin,
yesterday I've straightend out some of the glitches of the Train Track 9V parts.
Please download the latest version from the PT before continuing work.
Here's a summary of my changes:
- subfiled out the main body part portion of 2859.dat, 2861.dat into a new subfile s00 (which later should,
along with the other subfiles, become a ~part)
- replaced color 383 by 494
- unmirrored studs
- corrected origin of pivot to its rotation point
- corrected origin of 2859.dat, 2861.dat to match all the other currently official train track points, i.e., at the center of their straight portion
- changed 2859.dat, 2861.dat into shortcuts
- corrected positioning error in 2859.dat, 2861.dat: the pivot was in "branching" position, the lever was in "straight" position: tidied this up, so 2859.dat, 2861.dat now both are in "straight" position. Created additional shortcuts c00 in analogy to the 12V and 4.5V train points which represent the "branching" position.
- added shortcuts c01, c02 which add the yellow lever (currently a mockup).
- add the 3 missing primitives 3-8rin24.dat; 3-8con5.dat, 3-8con24.dat
- found the lever file on lugnet, BFCed it, loaded it up to the Parts Tracker
When somebody continues working on these parts, don't forget to update all necessary files and the subfiles,
i.e., start downloading top-down from
2859.dat, 2859c00.dat, 2859c01.dat, 2859c02.dat,
2861.dat, 2861c00.dat, 2861c01.dat, 2861c02.dat
LDView for example can do this easily.
My goal also is to get these out finally with the next parts release.
From my point of view there's just a handful of things remaining to correct:
(a) Some files need to be converted from subfiles to ~parts. Chris, I've put hold votes on the affected files, so you could easily find them.
(b) There are 2 files where 2 edges are too short, they also carry a hold vote
© If I remember correctly, I spotted a BFC error somewhere but am not really sure anymore.

I think I have straightened this out. To help I have created a Review Summary Page.

Still to do:
a) Create 2682 as mirror image of 2860
b) Create uNNNN as mirror image of 2863
c) Remove 2860 reference from 2859/2861 and add 2860/2862 references into 2859c01,c02/2861c01,c02.
d) Replace 2865s04r/2865s04l references in 2859/2861 with 2865s04 references and 6 correctly orientated studs.

After further research and discussion, we now know that these part numbers 2859-2867 refer just to the plastic moulded parts of these track pieces. So, I'd prefer to strip the metal conductors into separate uNNNN part numbers (we are very unlikely to discover the LEGO design IDs for these). But we do know the LEGO numbers for the assemblies.

Straight rail 2865 + metal = 74746
Curved rail 2867 + metal = 74747
Right Point 2859 + 2860 + 2863 + metal = 75541
Left Point 2861 + 2862 + 2939 + metal = 75542

In order to make progress, I'll re-number the existing 2859, 2860, 2861, 2862, 2865 and 2867 to ....c00 versions. That way we are not dependent on someone finding the enthusiasm to model the platic and metal components, but we do fit with our numbering schema.

I'm also thinking that the wires and conductor plates s/2859s03,4,5,7,8 could be uNNNN ~-prefixed parts.

I have added some notes to the c00 files as I after some thinking don't find them too useful,
now that we know the proper numbers for the points and the straight and the curved track.

One of our goals in numbering the files here should be to try to achieve an analogy in numbering
to the official 4.5 and 12V train tracks.
It is very difficult maybe to achieve, and will cost us perhaps some more renumbering iterations on the PT,
but I think we can make it.

Philo could dig these out, same as me. There are about 12 of them.

factoring-out the metal parts into separate files is anyway required
because otherwise their edgelines will not look correct.
we did the same with the 12V track at their development. it was the same way tedious...

Really? That's not what I see at parts/s/861s01. I see a subpart that is a mixture of plastic and metal components.

Re: 9V Train Track Points and Track

You are right, I went for simplification there.
The reason why the edges still look correct there is that all metal parts are of type 1,
and do not model the metal by quads plus edges.
Doing the latter would create wrong colors for the edges.

That glitch is what I wanted to avoid for the 9V parts.

I just grepped all the 9V files of the PT, and in fact, they don't have such an error.
So I retract my argument above. Coloring of edges currently is not wrong,
so no correction is needed by separating into metal/plastic.

I was referring to Philo getting the item IDs of the metal parts. There isn't one number for all the metal, it's many small pieces, and -- as with EVERY other number since 1994, we do have them.

That's great news that we have these numbers, even though these parts appeared in 1991. I withdraw my "we are very unlikely to discover the LEGO design IDs for these" comment.

They were still in the assortment as of 1994, making them "1994 parts" for the purposes of this discussion.
