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.
