Dear Wayne,
I have some (mainly bad) experience in building a roundhouse. So I will try to
comment some of the weak spots, that I found. This has been the first version
of the roundhouse in late 1999:
http://www-public.tu-bs.de:8080/~rbeneke/lego/fgltc/4te072.jpg
I try to give some comments on some of the topics further down, but on RCX i
cannot provide with any help. My roundhouse has been using hand power and
simply electrical remote control later. For the moment the turntable (and the
landscape around) has been destroyed once more (it will be the 4th one when
rebuilt again)....

I think I have been the first to invent this method. That solution has always
been highly satisfying.

Wow... My 4-bay roundhouse needed all the space of two 48x48 grundplates...
Since the track was (of course) not running under 90° angles and therefor clear
lines to divide it into submodules were not given , I have built the hole thing
(turntable + roundhouse) as one big module of 96x112 studs. Next to this
another 112x96 module has been placed.
But these have been not sturdy enough (the buildings on top began to break when
the modules were moved to the car. So in step 2 I have thickened the complete
modules from 2 bricks height up to 5 bricks. (Additionally I won space for a
better motor drive hidden under the turntable). The weight grew from 8 kg per
module to nearly 15 kg.... :-(
I was able to handle that in my appartment, but through doors it had to be
tilted under at least 30° to pass through. Carrying it into my car was
impossible without help of a second person. The module did not fit into the
cars of most other persons of the FGLTC. :-((
So this thickend version never made the way to any exhibition at all....

Same argument was valid here. But the consumption of bricks was horrible, the
handling too. And the hole layout became quite static. Every building on my
modules were standing in its place and there was no chance to move it.
Due to big amounts of needed bricks it was not possible to me (at least at that
time) to build it in other colours than yellow or red. I began to dislike it
after a while. I spread more "colour" dots (from a mosaic) into the yellow and
added more
details here and there to keep it on my level in art of building.
Still this module has never made it way to any show. :-((

The real roundhouses I know about are not using curved walls. They have the
shape of a polygon. So you can use the hinged bricks in the back as well, if
you want.

I only can recommend to divide the module into sub-modules. I think, since you
will always add your sub-modules to a complete module, the sizes of
the sub-modules might be chosen in any way you like. Dividing the walls (all of
them under none-90° angles) at any 48x48 border will be nearly impossible.

Can't agree more.... Concider even the use of 16x8 plates!

Due to the negative experience with my two 112x96 modules I have never
continued to keep on building further modules in that (or even smaller size).
I owned the probably only roundhouse in Germany, but despite of lots of work I
spent into that model, it has only been displayed 2 times at local train shows
(and only in the "light" and bending version (which afforded some rebuilding
after each transport).
That is the reason I continued building in a much more flexible style. I really
love the way the GMLTC has done its layout (out of thick 3-D modules), but I
learned that for a smaller club the "PNLTC-layout style" is fitting much better
You can arrange existing buildings everytime in a new way. Just put the
roadplates and track inbetween (each time in another way) and add trees and
vehicle to that. You can spontanous bring in any new building of any
none-expected-guest and you can easily close gaps (that are there, because
someone has become ill or has had a car breakdown on the way to the show
place).
Of course I can just speak for our small and highly chaotic FGLTC. I have
learned out of my experiences in nearly 10 shows that a table layout out of
lots of single buildings (directly built on groundplates) offers the best
possibilities for an always fresh and surprising layout. And you can put enough
stuff for several squaremeters into your standard car (I think not too many
clubs can afford trailers), which is important if you have long ways to drive.
With the modules I was not able to put more than ONE (out of two) modules +
some boxes with track and rolling stock into my car. Now I carry 1 box with
sturdy trees, one with track, one with groundplates, one with rolling stock and
the rest of the car is filled with as many buildings as I am able to put into
it. Then it's time to turn the key and drive to the show.
In the end my roundhouse modules have been destroyed a short while ago:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=170803
(lots of spare yellow bricks at hand right now, haha)
Now I plan to rebuild the roundhouse surroundings with a thickness of only 1..2
bricks. The roundhouse will be a sub-module of 48x96 (less than 5 kg in weight)
and another submodule will contain the turntable (this is planned to be motor
driven and in total not more than 2.33 bricks under the track). Will be a
challange to realize that. The colours of the "landsscape" is planned to be
tan, brown and green. Both sub-modules together are NOT planned to give the
shape of a rectangle. The free spaces on the edges will be free space for
baseplates or additionally buildings instead = more freedom in planning fresh
layouts.
Kind Regards,
Ben
P.s.: what are other clubs experiences with modules in the meantime?
