Not the Usual Turnout Frogs

[FCIN]

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.

Yep, that's what it appears to be. Funny thing about this turnout design is that it's sort a throwback. Reminds me of some of the old wood rail logging railroad operations and the way switches were designed on them. Will be curious to see if NS/CSX ever installs any of these on industrial spurs around here.
