No tram in Melbourne ever
had retreivers. Retreivers
are spring wound to pull
the trolley rope back into
them after a dewirement
which results in a sudden
jerk of the rope out of
it, thus pulling the
trolley pole down away
from the overhead wires.
All Z1, Z2, Z3, and the
first A classes, as well
as a few Ws, had trolley
"catchers", not
retreivers. Catchers are
designed to hold the rope
after a dewirement, but
are not designed to pull
in back in as a retreiver
is.  Unfortunately most
drivers, and to some
extent, depot shop
personnel did not
understand what they were
really for and they were
not properly maintained,
thus did not work
properly,and the end
result was ropes being
taken out of them and tied
onto the ends of a lot of
cars.  A properly working
catcher will catch the
rope after the pole
strikes the first span
wire and will then hold
the rope lower than all
the next span wires.  In
Melbourne though, more
often than not the catcher
would not catch since it
has not been properly
wound and the trolley
poles would just bounce
merrily from one span to
the next.  I will advise
on whether Number 1 still
has catchers when I next
see it, however there is
still one W and one Z3
with them, even though
there are no ropes in
them.  The Z3 that has
them has been equipped
with a pantograph for at
least 3 years now.  Of
course, this posting will
cause some busy body to
bring it to Preston shops'
attention, and they will
be removed.  If you see
it, take pictures while
you still can.
