That is where trolley buses come in.
I've never seen a trolley bus overtake another one on the same pair of
wires..

Is it possible in a pinch that the driver could pull down his
pantograph, drive round the stricken trolley-bus, and connect up again?

Or the driver of the broken down trolleybus could lower his poles and
let others pass, if the poles could cope with the angles. London
trolleybuses used to be able to travel a mile using reserve battery
power, so would be able to pull into the side of the road if the motor
was still running.

You can't drop the poles on a moving vehicle, though, and it's great fun
trying to get them back onto the wires in a hurry, especially in the dark..

There are eyes on the poles and they are spring loaded upwards. The
wires are "8"section, there is a pinching device.
There was a long bamboo pole threaded under the bus for the purpose
ofhooking/unhooking wires.
Best laugh was when the bus went one way down a junction and the poles
went the other way. (Someof the junctions had automatic "points" but
sometimes they got out of sequence.
There was a manual ring for the conductor to pull to move the
"points" on most junctions.
