I was able to follow the links to the full article:

Interesting switch, I imagine it would require two throws to operate.

I made one as a demonstration, and I did have two ground throws to make it
work. A friend of mine said the unions would like it because it provided
more work to do.
But Bob Stelmach of our SMSG club was able to make some with under-the table
linkage that moves all three points at the same time. He has a couple on
his layout and one on a portable board, just for show. Maybe he'll let me
borrow it and take it to the Fall S Fest as a conversation item at my
tables. BCNU all there?
Didja notice in that wikipedia article the statement "Swingnose crossings
are also useful where heavy rail [mainline trains] and light rail vehicles
[local streetcars &c] , WHICH HAVE DIFFERENT WHEEL PROFILES, share the same
track.? The first real-world example I encountered of this principle was
where two near-by German cities inter-connected their streetcar or light
rail passenger systems via the mainline railroad.
