Charles, not the same thing. Usually know as blade and mate, the
blade is a casting and shaped so it can direct the tram to either
route. The blade only moves about 75 to 100mm and the mate has no
moving parts. This is a photo of one in Melbourne. We have several
in use at our museum but I don't have a photo to hand.

The other one you describe was called a stub switch.

Weren¡¯t the single moving point turnouts quite common in streetcar
tracks in pavement? And still are where such track exists.?
Have seen pictures of underground mine tracks where one
movable rail was pivoted at the ¡°frog¡± point and the free end
moved totally from one running rail to the other. Obviously only
possible with very light rail. And short lightweight equipment.?
