It strikes me that auxiliary power would be the key to making trolley
buses work well. With a good auxiliary system, it would be possible to
run wires along the roads but have breaks at junctions. And, allow
run-arounds for broken down vehicles, roadworks, etc. Far, far simpler
and cheaper than the amazing, complex systems necessary without such
power.

The ones in Glasgow all those years ago could certainly move a limited
distance on their batteries. For manoeuvering in the depot, etc. Snag with
going round a broken one is the time needed to unhitch the pickup and
reattach afterwards.
