Surely the white lights which show horizontal (stop), vertical (go) and

I didn't say it didn't have signals, I said it didn't have a
signalling system. I'm assuming the lights at junctions are
freestanding installations of minimal complexity, and the tram lights
at road junctions are just traffic lights with unusual heads. There's
nothing more elaborate than that, as far as I know.

That's still a signalling system. A 'system' isn't *always* about technology
