Thank for the feedback. One of the big (HA!) disadvantages to building to
this scale is that everything else has to grow along with it. That is, any
train-related building has to get larger in order to fit in scale-wise, which
gets expensive and time-consuming! On the other hand, some of my larger
models are intended more as static display pieces, where they don’t
necessarily need to run on a layout or stand side-by-side with a building.
I am dying to get some of those BBB tires. I’m afraid they may be a bit too
small for a simple swap with the Northern, but I *know* that they work
perfectly right away in some of my other models (the BR18, for example). At
your prodding, I just checked again and was pleased to discover that the BBB
wheels were being sold, and tragically disappointed to realize that they were
temporarily sold out. I cannot wait for those to become available again ...
Are there any pics out there showing them in use yet?

I think a few of the Beta Testers have posted some pics. Here are a few links

Can you elaborate on where the dry ice bucket is? I sort of didn’t follow
that bit...

I snapped a couple more pics to show the area in question:
(clicking the above image takes you to the Northern gallery, where there are
some additional pics showing the concept)
The bucket is in a sealed chamber, so the dry ice vapor would not have to
fill up a very large volume before it could start escaping out the top of the
stack. Ideally, I’d rather have the steam coming out closer to the front of
the engine, but this was more of an experiment than an accurate attempt. I
figure that I could move the bucket further forward, and possibly use it in
conjunction with a LEGO motor and fan, to direct the “smoke” to wherever it
should be coming from.

Ah OK. I get it now, Where you have it is the “steam dome” which is a place for
steam to go, but if you see it coming out of there, it usually would be a not
very good thing (prefatory to a boiler explosion perhaps, or the safety valve
letting off, meaning prefatory to a arch burnout, which would be prefatory to a
boiler explosion) At least I think so anyway. There are steamheads here that
know better than me.
I think you want the steam coming out of the smoke stack....
The big clouds of billowing black smoke you often see in pictures coming out of
the stack are not typical.., they result from the fireman “shaking the grates”
to loosen soot inside the firebox for the photographers benefit. Normally the
smoke coming out of the stack is a lot closer to white, especially if this is a
loco that uses steam ejection to improve draft (which a late loco like the SP
Northern is very likely to do, but again, steamheads here would know that better
than me)
Also I noticed that you modeled an SP GS-3, at least that’s what your proto
drawing is from. Let’s see you do a GS-4! :-) That’s the streamlined variant of
the class... The most famous GS-4 is still steaming, it’s owned by Ross
Rowland... it started its career in SP Daylight livery, but wore Red White and
Blue when it pulled the American Freedom Train.. I think it’s back in Daylight
now. How’s your supply of red, orange and silver?
