Is This A New Switch Frog?

AIwould guess that is temporary for use while the panel is installed.  The actual frog to be installed afterwards .  That's just a guess however.

Three words...High speed line.  Prevents the bouncing of the trucks while going over switches at high speed. Used a lot in Europe on high speed lines.

yes, high speed. these are used on the Northeast Corridor.

Ok, I was half right then. But it does make sense. Does NS or CSX use this type of switch yet? I wonder if the new switch replacement in Mentor on the NS Lake Erie District has that feature.

NS uses "spring frogs" on mainline switches.

Personally, I don't see how that thing's supposed to turn.  Everything is anchored down, plus it's set opposite of the points. 

The only thing I'm sure of is it isn't a sprung frog turnout as illustrated below:

I bet there'd be some significant banging as time goes by on that short section of disconnected rail where the frog would be.   Linkage or motors to move this assembly also would add complication and to the cost of operation and maintenance.

I think I'd have to side with the temporary solution theory.

I happen to see this new uploaded video and am in question also. What would be the reason to have a movable switch frog, because that's the way it looks. Would this be classified as the Movable Point Frog or Swingnose Crossing so it reduces where on the gap on the frog?

Looks like sectional track to me!  They say that there's a prototype for everything. 

Lookslike a "jump frog" to me.

I agree with Dominic. After watching the video the frog does not appear to be a movable point frog, but looks closer to a “Lift Frog” that Progress Rail Services (another division of my employer) also offers for low usage sidings. Here is a link to their brochure for this “Lift Frog”.

So, in other words, the flange rides over the rail (10mph or less) while the guardrail opposite holds the truck on the track for a slightly bumpy ride into the siding.

Would that be a correct assessment?

Rusty,

Your understanding of the lift frog seems reasonable as I am a just railfan who has never had any railroad-related job.

These are just my opinion,

Only thing different I see between the video that's on youtube at the top and the brochure you gave is the photo to the right. As the video shows both rails are cut on both sides of the frog as where the photo shows one rail.
