It seems to be a railroad thing to eliminate the flange gap on main (or "mainer") lines. The sprung frog in the second photo keeps the gap closed but doesn't close up on the diverging route.
Ottawa station (the new one) used to have a patent model of a switch that allowed wheels to rise up and over the other rails.
Mt Washington Cog Railway had switches with loads of hinged bits that were flipped over the main rails to allow the wheels and the cogs to get over the rails into a siding.
