Stops the rear wheel falling off.

Is this a joke or do you mean if the nuts come loose the
chain will
still hold the wheel to make time for an emergency stop?

Yeah, what *are* the "functional difference[s]" between
track ends
and dropouts? I always considered dropouts better and
more modern
but now that I think about it I don't know how or why I
came to
that.

One advantage with rear facing track ends is that you can
have the
tire nearly touching the seat tube and still be able to
get the wheel
off without having to deflate it. That's because you don't
need space
with track ends to pull the wheel forward so the axle
clears the
slot. You do with forward facing dropouts.

Forward facing dropouts give you a good place to hang your
derailleur.

There is no real reason 'track' fork ends can't have a
derailleur, they just don't. The advantages of each style
are well known, but basically single/fixes/hubs like a track
end for 'easy' chain adjustment, every body else would use
forward facing or vertical for ease of getting the rear
wheel off/on. In my case, I use a vertical, with one of
these, albeit generic,

Which works very well imho, giving me the perceived
advantages of a hub drive, without the hassle of chain
tensioning or the fudge or a short reach derailleur. Yes
Andre, I know, I can live with it.
