In addition to a name for a switch, a wye is also a triangular arrangment of
trackage that allows a train or locomotive to reverse the way that it faces.
Similar to a "3 point turn" with a car, you proceed down one branch, reverse
to cross the "top of the triangle" then come down the other branch, and you
are now facing hte other way. Wye switches are often used in making wye
tracks, but it is not required to do so
Turning around is more important for steam engines than for diesels,
especially multiple unit diesel which usually are arranged so that the end
units face outward.
Hence wyes are relatively uncommon. Much more prevalent is the runaround
track which is basically a double ended siding. The engine "runs around" the
train and couples to the other end, then proceeds back the way it came.
