Many cities in France removed their trams after WW2. Some of them have
reinstated them since but it was a lot easier to do so with wide
boulevards. London is mostly different.

Problem with trams/trolley busses is they can't overtake each other and
go at the speed of the one in front. With narrow streets they cause
congestion.

We used to have a trolley bus route outside our flat, there was a
junction so the conductor had to get out to pull a chain switching the
poles in a form of overhead points.

You might be interested in how contemporary trams switch routes with
points in the overhead wires:

The trams seem to have the same type of pick‐up as the trolley buses. Is
it possible to combine pantograph pick‐ups with trolley buses? I’m just
trying to visualise it, the two cable systems would have to be at
slightly different levels, I suppose.
