Hi Draccus,
Thanks a lot for your comment.
I think your BR52 is closer to the real locomotive.
Made the coal door part.
Starting from simple base.
And added small parts one by one.
Fit check on the tensor body.

Hello Joon,
I can only repeat my words, amazing model created by your hands!
The only sad thing is, that we never will have a ride on your black beauty!
Thanks a lot for showing us your phantastic work!
Kind regards from germany!
Matthias

Hello Joon Kwon,
you are showing us another sphere of card modelling…
Great!

Thanks a lot, Helmut !
Not much progress today, but mostly on the dimension check for the tender wheels and the structure.
As the first step, made a mockup of the wheel structure and did the fit check. No obvious interference found.
Next, tried to check the wheel to wheel distance.
First, calculated the distance between tender wheels (based on original plan) and fount it around 59mm.
To make sure, I pulled the locomotive and measure the wheel distance and found it around … 54~55mm (I would say… 54.5mm)
54.5 vs 59mm
Don’t know what is the right number for the gap for 1/25 model, but it seems I need to go with 54.5mm to match that of Locomotive.

Actually both are wrong. (Well, at least for Germany. Poland might have some slightly different regulations for wheel sizes. So take this with a grain of salt.)
The Ty2 runs on standard track gauge, so the inner distance between rails equals 1435 mm.
59 mm * 25 = 1475mm, which is bigger than 1435 mm and thus couldn't possibly work.
In order to avoid the wheels running up the rail (which can cause the train to derail) the outer distance between wheel flanges (wheel gauge) must be slightly smaller than the track gauge. In Germany the wheel gauge must be inbetween 1410 and 1426 mm, so roughly 1-2.5 cm shorter than the track gauge. In 1:25 scale this would be at least 1410 mm / 25 = 56.4 mm and 1426 mm / 25 = 57 mm at most. Therefore ~57 mm would be the correct track gauge and the kit is wrong.
But i actually think that i know where Adrian Wandtke went wrong:
There is another measurement were the spacing of the rim backs (not sure about this translation) is measured . If you aren't paying attention or don't know the difference between the two, this could easily be confused with the wheel gauge. And wouldn't you know it: This distance equals 1360 mm, which divided by 25 is exactly 54.4 mm.
However all of that being said: You should stick with the 54.4 mm wheel gauge, that way the locomotive and tender match. A difference of 2.5 mm (1/10 of an inch) is also barely noticeable in this scale and i highly doubt anyone will be able to spot this, unless they are actively measuring your model.

Hi Johannes,
Wow, many thanks a lot for sharing the background.
Will go with 54.5mm this time.
When I ever make another locomotive sometime in the future, I’ll make sure I keep the wheel distance correctly.
Huge Thanks again, Johannes !

Perfect. The only word to describe your work, Joon.

Fantastic work (at the risk of repeating myself) - and the pace (without sacrificing quality) is breathtaking - one can only be jealous!!!
