Seems to me like some of the people involved in transport planning
need to
look up the definition of "rapid" in the dictionary. Trolleybuses
may be
many things but rapid isn't one of them.

What are your experiences which back up that statement ? The old
London
trolleybuses were very quick indeed with extremely rapid
acceleration and if
outright speed had been a factor in their design I don't see why they
shouldn't have been fast too.

I was thinking more about the fact that like ordinary buses they get
stuck
in traffic. But talking about shear speed they may have good
acceleration
but most of the the old ones topped out at about 40 or 50mph and would
probably have dewired before they got to that speed anyway.


Given that trolleybuses are primarily an urban vehicle how high a speed
would expect them to reach?

Strange that I've never hear shearing force refered to as speed before. It's
always been phrased in terms of the pressure required.
