12V Transformers

[Rene Rechthaler]

Hello, I recently got a Type 2 Transformer for the 12V Trains, should I do that one here in LDraw?
Because then I would also request the Type 1 (the one with the studs on top) including the old automatic switch buttons 7852...

[Rene Rechthaler]

Now I also got a Type 1, any need for that too?

[Stephan den Ridder]

Yeah! Awesome!

Go ahead.

While measuring the connections (already finished the 740 bottom) I found out that the old wide plug is missing:

I also found that one, do we need it too?

How should I number the transformers? They have numbers (740 and 741) on the bottom, but both are already taken, is it ok if I name them 740a and 741a?

Are there other numbers embosed on other parts?

If the old plug came with the transformator it should be modeled. Otherwise an existing should be used.

I dont have the other parts (740 seems to be the old roadsign BL bb0139pb01c01/02 and 741 is just the redirect to 641)
But both transformers seem to be named after their respective sets (they are supplemental sets which contain just the transformers).
Both numbers are clearly embossed at the bottom.

The plug BL bb0093a/bc01 fits both sets and is compatible with its newer version 2775c01. It is to connect the rail connector 511c01 or the automatic switch buttons (does anyone have them, they are missing yet).
Which number should that one have (didnt find one).

I already modeled the europlugs too.

Made a test:
   
(made in LDPE)

everything is now there, but some parts still need work...

[Rene Rechthaler]

Here the attempt of the 741 (yes I know that this one is named wrong and maybe also has a wrong structure...)

[Rene Rechthaler]

Would it be OK if I use u9602-9605 for the 740 and u9612-9615 for 741?
(the structure is very similar: top-bottom-knob-cable)

As stated earlier, in another thread, you need to ask our number admin, Orion, in a mail to  [email protected]

[Rene Rechthaler]

already did that two weeks ago (still no reaction), even mailed Orion directly and wrote him a PM here (also no reaction)

(maybe i bothered him too much)

Let me know what number you you want on each part, and maybe I can start renumbering the 740 trafo.

[Rene Rechthaler]

that would be my Idea:

740a.dat to 740ac01.dat
s\740as01.dat to u9602.dat
s\740as02.dat to u9602s01.dat
s\740as03.dat to u9603.dat
s\740as04.dat to u9603s01.dat
s\740as05.dat to u9603s02dat
s\740as06.dat to u9604.dat
s\740as07.dat to u9604s01.dat
s\740as08.dat to u9605s01.dat
s\740as09.dat to u9605s01.dat

and then I will upload u9605.dat with the cable as a part (as of now its made of multiple parts and prims in the final assembly)

Thanks in advance, René

This will have to wait, until Orion has found out a solution the the renumbering bug...

I got all of those messages. I ask that you please be patient. Between the holidays and my very limited time at the moment, I prioritize then things that get my attention.

[Rene Rechthaler]

Which renumbering bug?

Are the numbers OK? Or should I reupload them with the new numbers and you delete the old ones?

Is it OK if I upload the 741? (with a similar structure)

Which renumbering bug?

I found a bug in the PT renumber code that is causing weird things to happen in specific instances. I should have it fixed this weekend.

[Rene Rechthaler]

now that most issues are done, i still have some problems:
-the coiled cable s\u9605s01.dat has a hold because of the mismatches due to the rotated torii
-the europlugs have a hold because they cpuld be pims (but they are used only once)
-741ac01.dat has a hold because a link was broken (its fixed now)

that leaves one question: should I even include the cables? the 3rd 12V trafo (the new grey one) doesnt have one (but it could use one of the plugs)
How should I even do cables? Short+straight/coiled/dotted (like ine the 9V trafo 70928.dat)?

[Chris Böhnke]

I am not entirely sure about this, but shouldn't there be at least 2 transformers (12V and 9V) for each plug type? So the plugs would be used at least twice. Is there a sort of consensus on how many parts are needed to justify a new prim? I had a similar unsolved issue a while back with the Basic/Freestyle eye (https://library.ldraw.org/parts/39408).

Personally I think having the cable modelled would be nice.
But as far as I understand it "preformed" cables are not added to the library anyway, so leaving the cable segments for LSynth is maybe more consistent at the moment?

Some or all (?) of those transfomers also came with a special milky white plastic clamp to hold it coiled together. So either this configuration or one of those seen in instructions photos might be appropriate?

On another note, the existing models of train transformers don't have the info sticker on them. Should that be added as well?

[Rene Rechthaler]

I dont know if all transformers were availiable for all currents...

740 (Type 1): listed with 120 and 220V (120V has Set/Part number 742)
741 (Type 2): only 220V
u9058c01 (Type 3): BL has EU, UK and AUS version (Part number should be 7864, like BL)
for 9V: many versions

I have all 3 EU versions here and can confirm that T2 and T3 have the same plug (u9615s01, but 7864 has a different cable)
740 and 7864 have a round cable D6.4mm, 741 has a flattened one (u9615s03, 4x6.4mm)

What do you mean with info sticker? the 12V ones have the current info molded in at the bottom...
(i tried doing that with an ASCII table in the code, but that didnt work...)

(the 000 are the antistuds to connect the switches)

i used dots because multiple whitespaces tend do get erased, box sizes not to scale
