Looking at the photos again, I spotted springs, coil type, on each axle between the wheel and the journal. This indicates a centering device for the outer and inner shafts. It is probably not a Klein-Linder type system[...]

Japasha, thanks for the comment, the springs are for centering the drivers, but they do not neccesarily exclude the possibility that the drivers can change the angle. Of course I am not sure that this is possible and actually there is very little space for that between the drivers and the brakes. In any case, this solution looks very much like what has been used on the K-28 by LGB/Aster, although the are no springs there but a long wire connecting all four drivers and centering them. What is extra nice on the K27 is that all equalised axles seem to have the outer tubes which includes also the trailing truck. I do not know if we have a name for this engineering solution and this is why I referred to Klein-Lindner articulation which seems the closed to me in principle (of tubular axles) although different in detail (on all suspension axles) and perhaps greatly simplified (perhaps no angle change possible). Best wishes from Tokyo, Zubi

Correct spelling is Klein-Lindner of course, Sorry, Zubi

Nice photos. All drivers flanged, and still 4' radius? Lots of lateral play, I'll assume. [...]

Later,

K, probably not. Not a lateral play. What you can see in the photos are large diameter tubes and springs which likely indicate that an articulation similar to that of Klein-Linder type is used on the locomotive. This solution has been used by LGB/Aster on their K-28. Best wishes from Tokyo, Zubi
PS Probably the most well known application of the Klein-Linder articulation principle was the Brigadelok, here is the explanation: http://www.dself.dsl.pipex.com/MUSEUM/LOCOLOCO/klienlindner/klienlindner.htm

GEEE, Bob and Curmee, you both need a dedicated forum, I cannot find my stuff in between... Anyway, enjoy yourselves, it is a party day with a K like Bachmann showed! Best wishes from Tokyo, Zubi

Perry, with fully equalised suspension it probably run as if it were glued to the track! But I'd be happy to hear the reports too. Best wishes from Tokyo, Zubi

K, thanks for pointing out! What is the most amazing thing is the full compensation. Best, Zubi PS If Bachmann ever consideres another one K-28 or K36 are so much nicer than those inside frame EBT's

Yes.  Fully equalized.
Lee

Lee, Thanks, I just saw the photos in the Photo Gallery - WOW WOW WOW. This is a REVOLUTION, Zubi PS now if we could only convert this loco to live steam............

Gbbari, Magnus is not plastic. It is pot metal;-))), Zubi

Lee, a fully equalised chassis? Are you sure? This would be the first plastic engine to have that, well, if it is plastic of course;-) But not many brass electric engines have it either. Best wishes from Tokyo, Zubi

Hunt, Well, no I have not been reading your posts - sorry. But that does not have anything to do with you. I get bored and tend to skip scale and gauge stuff since Stan and a few other guys decided to mess up the perfectly good G-scale world;-)... I guess you are aware that the f-letter is a purely political and commercial concept and as such I tend to avoid it. Best wishes from Tokyo, Zubi
PS numeric 15mm is pretty international denomination, while 15 does not start with f in my mother tonque

Quote, Is that true? I do not think that Uintah or SV had outside frame Mikado locomotives. Best wishes from Tokyo, Zubi

Zubi, it most certainly is true!  It was Uintah #40, and it was used on one end of the line, it wouldn't make it through the curves on Baxter Pass.  (Obviously wasn't built for a 4foot diameter curve!  )  I'm pretty sure it was scrapped when the line went out of business, and I'm not sure how it compares in size with a K-27, but I'll look up the specs and see.

Hey, Bach Man?  How about a 1:20.3 2-6-6-2T Uintah Rwy articulated?

Robert

Robert, Thanks for the note. I do not have the Uintah books here in Tokyo so I am only referring to my memory. Well, the #40 does not look like outside frame in this photo; But the #30 in this sale flyer looks certainly more like it. Still, I think there are considerable differences between this and the D&RGW K27s but I have no precise data to compare. The 2-6-6-2 articulates are most fabulos locomotives, but I think that the right company to release them in foreseable time is Accucraft. And hopefully these will be live steam 2-6-6-2's!! Best wishes from Tokyo, Zubi

Zubi:

I've been in model RRing for nearly 60 years and in LS model RRing since the early 1980s (well more than 20 years). I, like most of the modelers I know, have always worked to be reasonably precise in our model RRing language, as well as our speech and writing in general. If we are going to be able to have meaningful discussions, then we need to recognize that items like scale, gauge, dimensions, grades, colors, etc. have specific words to describe them. A brown boxcar isn't called 'Green' just because someone likes, or first learned, the letter "G".

I'm certain there are some folks who just don't care if they communicate clearly. They of course can call it anything they want without anyone's permission or correction. By doing so, they just show their lack of knowledge and understanding.

To educated folks, 'things' have specific words and symbols to describe them. That's how we communicate with each other. Those are the folks I respect and want to deal with.

I too hope the K27 will do well, but it still isn't ". . . G scale . . .".

Happy RRing,

Jerry Bowers

Jerry, In that case you have been in the hobby for long enough to know better;-)...
Also, communication is about optimising information transfer not about accuracy of
a measurement. Most folks know what *size and gauge* G-scale stands for while
not so many know what the F-letter is supposed to represent - and who can
blame them... If I want to be precise, I refer to the scale representing 3feet as
45mm as 15mm scale and this is about the highest accuracy possible since unlike
F it carries both the meaning (the precise recipe how the scale is obtained) and
no error (unlike F or 1:20.3). So to me this K-27 is still G-scale if I want to be clear to
the general public. Best wishes from Tokyo, Zubi PS aren't these scale wars fun;-)?

Jerry, for all of us who have been playing with G-trains for more than a decade it is and will remain G-scale, Generic, Gross;-) and Good for the Garden! Hopefully, the new Bachmann K-27 will also satisfy those terms and join the large family of G-scale trains. Best wishes from Tokyo, Zubi

Similar power went all over the world, Columbia, Central America and so on. Don't forget the Sumpter Valley and Uintah which had similar  locomotives.

Japasha, Is that true? I do not think that Uintah or SV had outside frame Mikado locomotives. Best wishes from Tokyo, Zubi

WOW. Ubelievable. I suppose this will define the new large scale decade to come. I only hope that Bachmann will get the plastic right this time, it would be a big heap of dust if it crumbles after a year;-))) Best wishes from Tokyo, Zubi
