Not the Usual Turnout Frogs

[Gary S]

Looking closely at the (first) photo, you'll notice that there are long tie plates close to the frog which would indicate to me that this switch is designed to actually create a smooth flow through the frog, by moving the rail and closing the frog. Since the turnout has not been completely installed at this point - adjustments would still need to be made before it is placed in service.

With the "main" rail being solid through the frog, I don't see any other way except for the wheel flange to ride up and over. Gotta be a "jump frog" as Tinny indicated.
