There was an RV1 broken down on the Aldwych this morning, completely blocking half of the road.

Central London is constantly dug up and rebuilt with many bus route diversions.
A trolleybus wouldn't be able to divert along an unwired road.

.... unless it had a back-up battery or small diesel tank allowing a mile
or two off the wires, which would also remove the need to put countless
wires and junctions in the garage that were only used once a day.

How's the battery bus with charging pad in Walthamstow getting on?
