miserable failure too. Hopefully in 10 years or so they'll be sold on and

On that subject I'm not entirely sure why successive mayors have never
even considered trolley buses, at least in part like in Boston where its
electricpart of the way and a diesel engine takes over where the wires
stop. Seems to me it would be a perfect solution for central london.

Central London in times past resisted overhead wiring on aesthetic
grounds and there could well be objections to them now though at least
it can be argued that modern overhead can be engineered with modern
materials and looks a lot less intrusive than the big ceramic
insulators and heavy Ohio Brass* components of the former trolley bus
network.

I don't recognise anything in that catalogue as like the London trolleybus
wiring of my youth.
