I was just looking thru some images I had saved on my computer and ran across this one,..

 

 

82551-1.jpeg 

Its termed an 'EXPRESS' by Fleischman.

1) It appears to not have any discontinuous point-rails to closure-rails,..they are all one.

2) There is almost no gap (or very little) as the wheel crosses over to the frog portion. (no wheel drop regardless of flange size)

3) Almost no need for guard rails (but maybe need to be included for prototype appearances)

4) Metal, powered frog, .....no problem (insulate the frog rails like we do Pecos, etc)

5) One single pivot point for the direction-selection track assembly?

Hinged points and frog

Looks to me like the point rails are separate from the closure rails, with the typical rail joier like hinge about halfway between the points and the frog.  The frog is unusual - if you hold a straightedge up against the upper side of the shiny frog point casting you can see it doesn’t line up with the diverging route rail.  That frog point casting itself must be hinged so it rotates as the points slide across, with some connecting mechanism under the turnout.

Neat: Illuminated Point Lantern

Below is more information about a neat add-on

Vendor description: 

Point lantern to optionally retrofit for a left, a right, or a three-way point. Illumination with maintenance-free LEDs. From the turnout independent power supply. Can not be used with double slip switches and high-speed switches.

I saw that hint of a joiner also, but what if it were just solid rail there?

Not sure I see what you are speaking of?

I wasn't think that that the frog needed to rotate, but rather those inner tracks would rotate something like these old turnouts,  but modernized ?? (this is what i was referring to as a single rotation point)

Old design

That switch design concept has been around since True Scale track back in the 1950's.

Continuous Rail Turnouts

There were 2 articles way back in MR that described how to build these. All my stuff is packed up and buried deep in the garage until after we move.

The idea with those turnouts was that the point rails and closer rails were on long rail with a sharp bend at the points. There was a pivot  spot somewhere along the length. The bend in each rail allowed for the gap at the points I think. Memory gets pretty hazy on how they worked.

They did according to the authors work extremely well. This was pre DCC and I don't know how they would work with DCC.

Closed Frog Switches

Looks like a similar subject thread came up back here,..

Closed Frog Switches

@Ken,
You were correct, those rails were separate,...as shown by a video within that other discussion.

Fleischmann called these

Fleischmann called these turnouts with movable frogs "high-speed turnouts. The movable part of the closes the gap.

Here is a pdf-file with spare parts that shows the mechanism from the bottom: https://www.fleischmann.de/doc/et/2/de/6179_13499.pdf

The turnouts are discontinued.
