No time was needed. If a bus broke down, the conductor immediately

On every junction? I think not.
More than once I saw them stuck in awkward positions, so that
unhooking the overtaking one was needed, or there was a problem with
the supply on that stretch, etc.

How could it overtake if it was unhooked?
I think you're making all this up.

Most, if not all, trolleybuses have a small battery pack on board for
moving the vehicle round the depot or travelling along short sections of
road where there is no overhead supply for some reason. Most of them can
travel up to a mile at about 20mph, which is enough to bypass roadworks
or a broken down bus.
