Yes, this is how the ones I have seen work too. Is there actually going to
be wire on the layout, though? That will be something to see! I have seen it
done on O gauge MR layouts but it would take a lot of non-lego parts.
I guess it depends on whether you think the pole up / pole down is worth
bothering about compared to the many other non-prototypical things our Lego
trains do :-) I personally would be more surprised to see a trolley car
being turntabled at the end of its run, than I would notice whether the pole
is up or down at the correct end if there is no wire.
The SF cable cars are a special case and I don't think they can be compared
with standard trolley cars, if we're thinking of the same ones that go up
the steep hills.
