This may sound like an Aldi advert, I like this one and I like this one but...
This would be quite good. There maybe times at exhibitions due to space constraints where this would work and be very interesting 8 modules coming together to form a roundy, roundy 'standard' exhibition type layout to show people that they can bring their home 'layout' to an exhibition and show of the collective power of RMWeb, it may just need more explaining to the public what's happening so they get the idea. The problem though I see is that you would need to introduce a length standard to the board so everything matches up..
This actually appeals to me , I'd rather enter the group as a basic beginner with either a straight board or a corner board with just one or two tracks with basic 2 wire electrics and my interpretation of scenics which I see as a step up from my APA box.
Then when I find that the whole thing does indeed manage to fit to the other boards (the first hurdle) I can learn from other boards as to the how and why then look to step up again.
I find the whole thing interesting and a way to get to be part of a larger layout with my little bit that I cant have in my current layout area at home.
I personally think it would be better to stick to the spacing that is offered by joining 2 points together without any cutting or adding of tracks.
The problem seems to be agreeing the two track or more system, the single track on a board shouldn't be a problem it just seems to be height to top of track standard and distance to center of track from the front of the board that needs to be established if I'm picking this up right.
