Is this kind of railway crossing, where the wheels are running on the flanges, common in other countries? Here in Sweden it's quite rare, though it can be seen now and then in industrial environments as in this retired example.

Current practice is experimental, sort of, with the high speed rail passing right through without a flange gap so that impact wear is eliminated. The crossing track has the flange riding up and over right on the rail head, so it's a straight-line and slow speed movement. I've only seen them in pictures so I gather they're currently very rare. In this case, it might be to reduce noise as well.
Seems like I've read about low speed switches that do essentially the same thing for the branching movement. Again, the idea is to eliminate the flange gap and impact wear, but it means a slow and bumpy ride for the engine and cars taking that siding.
I've yet to personally see an instance of a movable frog; I think those are used only on very high speed tracks.
