For you members who do not know, Bill has developed a sound system for his 2 rail engines that is just beyond belief, even over the phone Bills train room sounds like a real train yard in action.
If he ever makes it small enough to have in our O gauge stuff, it will change the entire O gauge sound world, into a reality train world, just because of the incredible realistic sounds.
If it fits in a 2 rail O Scale, why would he need to make it smaller to fit in a 3 rail O scale? I've never seen a 2 rail O scale engine... is there a major space/size difference?
