I can't see battery power being useful for more than a mile or so and
in hilly areas I suspect its a non starter - literally. The other
problem is that if an operater buys a trolleybus with a diesel
engine , you can guarantee that at some point the bean counters will
say "well hang on , this bus has an engine anyway , why are we paying
to maintain overhead wires when the bus doesn't actually need them?".


IIRC (it was over 40 years ago) the Newcastle trolleybuses' diesel engines
were quite low powered, and were provided to allow the 'bus to get out of
the way if there was a problem with the wires or pickup arms, but not for
normal use...
