Great news--thanks for the tip!

Too bad Eishindo doesn't keep their website up to date. |
Or keep their dealers up to date. I've yet to hear anything about them being ready. Perhaps they don't yet have sufficient stock to supply all dealers.
Their 'Animals' set has not yet appeared on any price lists, nor have I received any advice that it even exists - yet they are on sale without a doubt. _________________ Darren,

With that sharp angular deviation from the straight through line, and after looking closely at the vid on the Gaugemaster site I think that these may be single bladed points!
If you zoom in on the vid you can just about make out the blades apearing to move all the way across the track at their pointed end but pivot at the frog end!
I wonder if I'm seeing that right |
Visit the following page, scroll down, and watch a video of the turnouts in action. The image is nice and close. You can see that the points are in fact two rails, just spaced very close together--virtually parallel. Also, the diverging route is not curved at all--it leaves the straight route on a sharp angle. Amazing things still work...

What magnification are you using? To me it looks like a single rail on a wide carrier, pivoted about half way along the blade! |

I agree with David.
Mind you it looked like a length of U channel to me.

Magnification? None. Just observing the video. I snapped two stillframes from it, one in each position, and I think it's pretty unambiguous (and I agree with Ian that it looks rather like U-channel):

So? That's basically what Kato does in N scale. The points on their long turnout are a single piece of metal, stamped and formed into the points. The toe and heel are joined, the space in between stamped out.

Looks to me like a cross between one of the old O gauge tinplate things and a single bladed point. Obviously I'm at the limit of pixelation, but it looks like this:
Mike Mott on the Gn15 list built a layout with single bladed points, but this is better - no need to solder up a frog (in Gn15 terms). Yes, it looks like channel, which is what I would have done.
Short wheelbase or bogie stock will traverse this stuff quite well (although I'm surprised about the speed, probably partly the magnetic wheelsets). Sadly for those who wanted to cut the bogies up to make longer rigid wheelbase stock, I suspect that this beastie is engineered to the limits.
I may just have ago at one of these in 9mm gauge for O9. If so, I'll let you know.

Sounds plausible, except when you examine the video carefully and watch the action: only one end moves, and the pivoting is definitely from the other end. I also took the two stillframes and superimposed them, which indicated pretty conclusively that the pivot point is located where the red dot is placed in this image, and that nothing in the area of the frog (or to the right of the dot) moves at all:
What's a much bigger mystery to me is the geometry of the frog. I just can't make out how it's designed; it almost looks like some crazy half-frog thingy. _________________ —David

I think we are pretty close to reaching the limits of productive speculation on this turnout.
* This was an engineering sample shown last June.
* The newer sample shows a similar point design, but totally different geometry.
* As for point geometry, I'm confident that David's analysis that it's a one piece, two rail point pivoting about midway between the frog and the point ends is correct.
* As for the frog and other details, I think we are reaching what the resolution of these photos can tell us.
As for the speed that the trains go through it, it's an example on how inertia doesn't scale. At 1:450 100 scale mph through a turnout the train is experiencing the equivalent acceleration of the prototype going through the same geometry at 5 mph.
