New in the OO9 Society - and some NGG16 questions

[ADanti]

the "design department" keeps on creating..

some additional parts added tonight:

Have you thought about couplers yet?  I imagine you will build in NEM coupler pockets.

[ADanti]

Hi Tom,

I am still far away from those details - but yes, I'd use NEM couplers.

One possible open question is how to deal with the height of the coupler on the engine compared to the height of the coupler on the carriages.
Not that there are many possibilities to change that on the NGG without redoing the engine frame front, as the coupler pocket would have a very specific position.

But this as well is a good point that I marked down in my "things to consider" list, thanks :)

On a side note, I found an interesting document about couplers on model trains from the BMR website, I suppose that it is old information for most of you but I'll post the URL here
as it is nonetheless an interesting read: https://www.buffersmodelrailways.com/image/data/couplings.pdf)

It won't go direct to a pdf. file, Alex. For those wanting to read it try going to this page and then downloading the coumplings file from the bottom:

Things have moved on a lot since he wrote it in 2011 and said this: "Most modern stock in use on the non heritage lines use the buckeye throughout in one form or another" though! Most now use variations of the Scharefenberg coupler these days (the Dellner Coupler), though most can't couple to each other due to electrical connections being different! Someone does a model version and several narrow gauge lines over the Channel use a simplified version of it.

Oops - just noticed as well that the link doesn't work as I expected - sorry about that and thanks to Hobby for the correction.

Indeed, the document it's already 7 years old - but the subject of coupling height is still something that it is being actively discussed today, at least in the italian and german model railway forums that I follow. Hence my decision to share it over here too, maybe someone else could be interested.

Related to my NGG16 design, as I mentioned in a earlier post I am still far away from the subject of coupling - which type of coupling is still open, but it makes sense to me to have a NEM coupler pocket, so that I can have a number of options to test.

If I have to think now which kind of coupler I'd like to use, I think I would tend to a knuckle/buckeye-style coupler (like the Kadee, of which I have already some in service in my Bemo Rh.B. models).

Keeping up with the NGG16, some additional parts added (or carved):

[Tom Haythornthwaite]

Alex - I have sent you a private message.

[ADanti]

Another (short) weekend update, added central dome cover, carved the cab and added windows and front and back lights.

[ADanti]

Work has now started on the wheels..

[ADanti]

Time for a new update!
Wheelsets are done, at least for this first iteration of the design.

Coming up next: axles, bogies, and axleboxes

[Tom Haythornthwaite]

... but surely you won't be printing the wheels, axles, etc.?  I'm a bit confused - but very curious.

[ADanti]

No, I am not considering printing the wheels and axles - but I need to have a precise reference object to model the bogies, the axleboxes and - when I get there - the cranks, pins, rods and the cylinders.

[Tom Haythornthwaite]

Aha, understood!  Please keep showing us your updates.

[ADanti]

very small update for tonight, as I am half sick and I can't focus properly.
Outer bogies frame (not complete).

Good night
Alex
