When I was a young kid in the late 1950s/eearly 1960s we still had trolleybuses in London. My local major junction was Golders Green Station. This photo I found online shows just a fraction of the overhaed wiring at the junction and bus station.

Apart fom the wires this view is remarkably similar today.
For a forest of overhead wiring this shot I took in Buenos Aires almost 2 years ago is pretty good. There's stuff elswehere that makes this look very modest. This one from Thailand looks fun:
